YouTube - How to Upload Your Video

If you think about it, there were almost no videos on the internet before YouTube came in the picture. Now millions of videos are uploaded to YouTube every day, and regular people like you and me are using it as a channel to express their opinions, views and feelings.

Uploading videos on YouTube is fairly simple. But first you need to create your YouTube account. Go to YouTube.com and search in the upper right corner of the website, you will find a link named "create account", follow the instructions and you will create your account. After this you will get a new email from YouTube to the email you used to create your account asking you to confirm that you created an account using that email address, follow the instructions and click the link, it will take you back to YouTube where you will be logged in.

Now that you are logged in, you can find a link in the upper right region of the website named "Upload" click it and it will take you to a page where you can upload your video. There will be a big yellow button with the text "Upload video", click it and you will be given the option to select a file from your hard drive, browse trough your computer and find your video and click open.

The video will start uploading to YouTube, while this is happening you have the option to choose your title, description, category and tags. You also need to choose if you want the video to be public, private or unlisted. Public videos are available for anyone and are listed in the YouTube search engine, private videos are only available for you and for users that you give special permission to see the video and unlisted videos are videos that don't appear in the search results in YouTube and can be accessed only trough the special URL for the video (really handy way to share your video only with your close friends)

After the video is uploaded, YouTube needs to process it, this process involves checking for copyright and converting the video in different formats and qualities so it can be accessed from slow and fast connections and from mobile phones.

When the processing is complete, usually takes 5-10 minutes, your video is officially on YouTube.

However you might have problems with your uploads if your video is in unsupported formats or contains copyrighted material (usually copyrighted music).

For now YouTube supports these extensions:

.MPEG4.3GP.MOV.AVI.WMV.FLV.MPEGPS

If your video is in a different format you will have to convert it to one of those formats and then upload it to YouTube.

Converting videos from one format to another was tricky few years earlier when you couldn't find a decent free converter service, However these days there are many online services like convert files.com that can do this for free.

The next step you can take after uploading your video is to make sure it gets more YouTube views or you can learn how to get more subscribers on YouTube

What Would Make a Good Site for a Data Centre?

Increasingly companies are recognising the dangers of locating their IT departments along side their data centres. For many it is very convenient to have offices in a city centre block as it gives the company access to local business services and the staff good transport, shops and other local amenities. However such a site may be less than ideal for locating mission critical servers as the security offered by such sites cannot be guaranteed. Risk assessment undertaken some years ago probably would not have taken into account many of the dangers found in our global world today, making it time to re-think data centre sighting.

So what needs considering today when making this big decision? First of all to be open minded, considering all options. These include casting the net far and wide as the improvements in technology and networks now make it practical to not only think local but also consider data centres in Europe or even the rest of the world.

Natural disasters

Location, location, location as ever is all important, as it needs to offer security against both natural and man made disasters. In recent months we have seen the effect of earthquakes, tsunamis and flooding all over the world. Can they happen here in the UK or Europe - Yes they can. Much of London for example, could be effected by tidal flooding, and we have seen flash flooding in cities as divers as Gloucester, Hull and York. Not to forget two earthquakes this year measuring 3.6 in Ripon too.

Surprisingly, if not a little far fetched, the West Country is thought to have suffered from a tsunamis many years ago resulting from the movement of a tectonic plate in the Atlantic Trench. These caused flooding to 200 square miles, killed thousands and would have wiped out any data centres had they been around. Could it happen again and when, who knows!

Finally for natural disasters we cannot overlook pandemics. Luckily the last, the Swine Flue outbreak, was not a killer unlike Spanish Flue that killed millions. Should another wave occur that was more virulent then data centres in areas of high population would be at much greater risk.

Problems created by man

Man-made disasters, which can impact on data centres, come in many forms, such as fire spreading from adjacent buildings, terrorism or civil unrest as seen in the past in London and more recently in Oslo. Not to forget IT equipment theft, which are thought to be "to order" resulting from the high value of the kite used. So far 2011 has seen outages in data centres in Basingstoke and East London, causing distress to thousands.

Once you have found a location that avoids the problems identified above and is constructed to withstand the most invasive attempts of international crime to break in, then think power. Servers, at the micro level, over the last few years have steadily demanded more and more. Not so long ago a rack might draw 1.5 kilowatts, where as today it could have a thirst for 10 kilowatts or more, typified by blades and high frequency trading. On the macro level this means that a data centre may require to 2 or 5

How Solar Generators Work

Electricity is extremely valuable to humans. It is a part of our daily need that needs to be maintained because the absence of it may cause a significant imbalance in daily life. Most instruments use electricity to function. At present, there are a lot of resources for generating electricity, one of which is the use of solar energy.

The sun is a solar energy source that can produce electricity with the use of a solar generator. This converts the sun's heat into electricity with the use of photovoltaic (PV) or concentrated solar power (CSP). The generator has 3 vital components: a solar panel (PV or CSP), a battery, an inverter and a voltmeter.

A solar generator works with the use of solar panel, battery and an inverter. A solar panel is the instrument that collects the light of the sun. This can be PV or CSP. Photovoltaic (PV) is a solar cell that utilizes photoelectric effect to convert light into electricity. On the other hand, concentrated solar power (CSP) utilizes lenses or mirrors to collect the sun's light to be converted as electric current. For higher power output, use polycrystalline or mono crystalline silicon panels. The solar panel must be situated in an area that is mostly exposed to the sun. It must be positioned at 20 to 50 degrees angle in order to gather the sun's energy well.

A battery is another part of solar power generators. The battery woks as a storage device for the collected electric current from the sun. This is essential especially during the rainy season or the winter season where the sun is not available all the time. The battery for must be a deep cell or continuous battery. Commonly, the battery is 12 volts thus the solar panel must collect 12 volts or more in order for the solar generator to work. A voltmeter is essential to measure the incoming and outgoing electric current of the solar power generator.

An inverter is a part of generator that converts the direct current (DC) collected from the sun to alternating current (AC). Most household device utilizes alternating current thus it makes the inverter important.

Solar generators are cost effective and environmental device. Aside from it saves money, it is also portable to some extent. This can be used in camping and fishing activity. The availability of the sun (rainy season, winter season, night time) can be the disadvantage of the solar generator.

The best step before diving into the project yourself is to read on the reviews about ones that already exist. Solar generator reviews provide a general outlook on others experience on the device. The reviews provided by previous user can serve as a guide before creating one. Some of the reviews provides errors occurred by the previous user which can be avoided by the other user. Moreover, some solar generator reviews give advice on the best materials to be used for creating one. Some of the reviews gives insight on the mathematical calculations needed which is the common mistake in setting a solar generator. In addition, guides such as "my solar backup review" found in the Internet provides beneficial tips.

If you would like to go green and get in on the solar generator craze, be sure to check out the latest solar generator reviews. You'll find information about all the latest solar generator products include the popular my solar backup review.

Underage Drinking in America Reaches Epic Proportions: ID Scanner Protects Alcohol Proprietors

ByAndy A. McMahon

The CDC reports that the teen alcohol epidemic in this country is rising at an alarming rate. The trend over the last three decades shows dramatic increases in underage drinking and there are no indications that the trend will reverse. Contrarily, research shows that underage drinking continues to escalate. In a survey conducted in 2009 by the Center for Disease Control the results show that of all the alcohol that is consumed in the United States every year, 11% is consumed by underage youth, ages 12-20 years of age.

Technology is keeping up with this epidemic by protecting convenience stores, liquor stores, and supermarkets and their respective liquor licenses by use of the ID scanner. An ID scanner electronically reads the information directly from the magnetic stripe to verify state issued information. Without this type of security device retailers are often defrauded with altered identifications resulting in state punitive damages, possible suspension, and fines or loss of license.

Collectively law enforcement and license regulators know that the majority of underage alcohol users purchase some form of fraudulent identification. In an effort to combat the underage drinking national epidemic state legislatures have sweepingly increased penalties to store owners, and establishments for serving and selling to minors. So how can these proprietors protect their liquor licenses? In some states liquor licenses are no longer available to purchase as states self-regulate the number of licenses issued. The ID scanner can fill this natural void and is an expense that could save these establishments their legal licenses to serve alcohol.

Bars and nightclubs were the first adopters of the ID scanner. ID scanners can hold up to 4,000 records of the previous scans. With this much data the establishment can quickly report to any inspections conducted by state regulators. Now that the underage drinking is disproportionately growing ID scanners are being put into use by retailers. Bar owners and nightclub proprietors were using ID scanners that functioned in complete darkness, but many different options of ID scanners are on the market now.

The ID-E-01 is an ID scanner that scans licenses identifications to verify the information on the form of identification presented at the time of purchase matches that of the state issued information. This point of sale ID scanner security device requires the proprietor to swipe the identification through the machines scanner like a credit card. The ID scanner then displays the date of birth, the age, and the expiration date of the id as it appears on record with the state's driver's license bureaus at the time of issue. The age display on the ID scanner is three times the size of the other data. Sellers of alcohol can confirm with one swipe instantly if the identification is legitimate or has been altered in anyway. Security devices such as the ID scanner will go a long way in protecting the liability of the alcohol proprietor in ensuring their licenses and livelihoods are never at risk.

Crown Security Products offers many security and pro-active equipment for business owners and professionals. For more information regarding the pricing and extra features offered in their lines of technologically advanced ID scanners and other money saving and protective equipment visit them on the web directly at: www.CrownSecurityProducts.com

Determining The Best Opportunities Of AV Equipment Sales Or Rentals

ByAndrew A Parris

AV equipment represents one of the best resources companies can take advantage of when they regularly utilize presentations to encourage consumer sales, increase business partnerships, and inspire their primary employee base. There are many opportunities available for a company when making this investment and determining the best solutions available to you can help in saving money as well as increasing company potential. When weighing the opportunities that are available to you with this technological investment, it is highly advisable to determine whether you benefit from AV equipment sales or rentals.

The first opportunity that many companies seek to take advantage of when pursuing this technological resource is found with pursuing AV equipment sales. There are many positive aspects that exist with this technology including the opportunities that are available with always having these resources on hand regardless of the environment they are required to be utilized. Furthermore, your associates or presenters can begin to familiarize themselves with this technology as you utilize it to inspire employees, drive sales, or encourage investment potential. While this may represent a short-term expense the long-term savings are high when compared with regular rentals.

While there are many positive aspects associated with the opportunities that exist with AV equipment sales, it is also important to identify the potential negatives of this investment. Technology is constantly growing so your investment can swiftly become outdated in a very short period of time, creating a need for reinvestment. Another aspect of concern is found with the need for repair or maintenance on these resources when your business associates are unfamiliar with the technology they are attempting to utilize.

BA Methods - Fads and Fashions

ByPreeti D G

Technologies come and go, change MUST cover all the same topic to analyze the business requirements for a new business solution. Why are there so many methods for doing it? Could it be that being a BA is hard and every method claims to incredibly make it easy? Could it be that some methods are designed to help developers develop a code and not the business development for the business solutions or could it be that there is more money in these new methods?

This converse was given at the Project Challenge show in Olympia and intends to debunk the subject area and expose what is - in essence - the simple (if hard) process of business analysis. It uncovers the framework that is behind every method and makes the case for a pragmatic and practical use of that framework in the analysis of business changes.

Business Analysis Chain of Reasoning

There is a chain of reasoning that leads from a statement of a problem to the definition of a solution. If any part of that chain is missing, a poor quality solution will be delivered. This paper presents a high-level overview of the logical steps involved in transferring from problem to solution.

Two Perspectives: Sponsors vs. Business Analysts

This article proposes that sponsors have different expectations of what role and function BA's play in a project change compared to the role and function that Business Analysts need to perform. This mismatch of expectations results in sponsor and BA disturbances. The solution suggested is that, Business Analysts need to demonstrate through performance of their activities that their role and function is a logical consequence of project change life-cycles - that there is no rational alternative for successful projects.

Computer Aided Software Engineering (CASE) tools

At the Provision users conference a question was raised concerning the poor take-up of CASE tools.

This presentation provides the reasons for the poor take-up of CASE tools commercially covering the scope of Business Analysis, Business Models and alignment with strategy.

Sometimes projects fail and we need to analyze the reasons behind it.

This presentation analyses some real-life examples of what goes wrong, why and what BA should be doing to mitigate the risk of failure. It challenges the idea that Business Analysis is hard or that it is an art. It is more closely aligned with a science which follows a chain of reasoning leading from the precise definition of a problem/opportunity to a set of solutions, proving every step of the way that each subsequent step is aimed at resolving the problem/exploiting the opportunity.

The importance of the Business Analyst role

This article proposes that as a programmer cannot proceed in a rational fashion without the activities that the business analyst performs, BAs must be considered fundamentally important.

What Is a Human Machine Interface?

ByAnthony Tuccillo

A Human Machine Interface or HMI is the graphical display that represents a machine, process, or facility so that the user can easily, intuitively control and monitor the status of such a system.

A simple machine will require a simple interface for the user and not require a HMI. A few indicator lights, some push buttons and switches will be all that is needed to operate a simple machine, say one that presses parts into a casting of some sorts. To quickly give you an idea of what the lights and push buttons would do, is to inform the operator that a part was in place and ready for the next step along the line to a finished piece. The operator would know now the machine is ready, add another component to the part and push the appropriate button to begin the next action.

Way before there where the great color displays of today, a panel (metal, plastic or even wood) would be created and imprinted with a simplified version of the actual process. At key points on this panel, holes wold be drilled and indicators and pilot lights installed. This panel would be mounted on the wall and the panel for the switchgear such as push buttons and selector switches, mounted below. Typically placed at desk height to allow the operator to control the machine or process.

Keep in mind that the Human Machine Interface is just...well... an interface. What I mean is that the real control and intelligence is handled by a controller, usually a PLC, although integrated HMI/PLCs are available. The HMI sends a request for an action by a graphic push button pressed by the operator to the controller. In turn an action is performed though the intelligence programmed into the controller and the machine actual producing the action. The PLC through sensors placed on the machine can send this status to the HMI.

The HMI can be a self-contained touch screen device made specifically to be used with a particular brand of PLC or controller. While others are more universal and can be used with many controllers since they have most communication protocol included or communication drivers available. Usually, you will see these mounted right on the enclosure door of a control cabinet. The HMI is also the user's front end to a SCADA system's controls and databases. Essentially SCADA is the top level of control of a network of PLCs controlling a large, complex process.

Other HMIs make use of a software package and adapter for a common PC. The adapter card is inserted into the PC to enable connection to a specific communication medium and protocol of the control system. Depending on the supplier and the power and complexity, the software package will contain a development system and run-time license. In this way a developer can have one system for creating the design of the HMI and multiple less costly run-time licenses for use on every machine.

Good design is necessary to obtain the most benefit from a Human Machine Interface. The Screens that are created, how they are laid out and how it all flows together can make a huge difference. Generally a Main Screen, Overview screen for each main area or system, a Current Alarms and Alarms History screen are a good start. The Overview screen will provide access to more detailed sub screens through a grouping of push buttons and/or logical drill down points on the Overview screen. Easy navigation to and from connected processes is necessary as well as to the main screens.

Choosing the correct graphics from the included library and creating your own is important for depicting your machine or process so that operator will learn quickly and not become confused.

The included graphic libraries have cool looking indicators, push-buttons, meters, numerical displays, tanks, piping, valves, motors, blowers, etc.

Creating a great HMI is part art, part engineering, part psychology. A thorough understanding of the process is necessary and it can be quite a bit fun, especially for the creative types among us.

Anthony Tuccillo is the editor of PLCEdge.com - the free information resource about PLCs (programmable logic controllers). Find more about PLC SCADA systems, of which HMIs are the front end, at his site.

Using Your Personal Computer As a Motion Detecting System

A motion detecting system is one of the most useful inventions when it comes to home security. More and more homeowners now have these systems installed in order to prevent burglars from breaking into their homes. For those who do not want to spend some money to buy motion detectors and want to experiment on electronic devices, it would be interesting to know that a personal computer can now be transformed into a motion detection system.

What Will Be Needed

The main requirement will be a personal computer running on either Windows 98, Windows ME, Windows 2000 or Windows XP. A web camera is also required for this set up and a free or open source webcam utility (such as Dorgem).

In the event that the personal computer becomes unavailable, you will also need to have a File Transfer Protocol (FTP) account in order to upload the captured images 'off-site'.

How to Set It Up

Assuming the web camera has already been in the computer, the next thing to do is download the camera utility (like Dorgem, which is a free utility). Once it has been downloaded, install it and follow the instructions in order to install it correctly. Once installation has been completed, launch the camera utility and select webcam from the selection on the drop-down menu for camera selection.

Click on the preview button in order to check the view the webcam has. Adjust the camera physically so that it is able to capture the area that will be monitored. To make adjustments on the camera settings (contrast, brightness and other settings), click on source. Click on OK when done with the adjustments.

On the options part of the camera utility, look for the options button and look for the option for motion detection. Check the box beside it and click ok.

For storing the recordings/captures, you will a need a profile. For this, open the camera utility's main window and look for a 'storage' option and click on it. If it asks for the storage type, click on 'File' and click on OK. To set up the storage settings, you will have to enter a name for the file and create a time interval. It would be a good idea to set a short time interval (in seconds). If there is an option asking for a filename, you can set the filename to whatever it is you prefer. This filename will be the default filename of the captures made by the webcam. Click on the OK when setting up of the storage settings is done and then close the camera utility's main window.

Testing the Improvised Motion Detector

After installation is done, test it by waving in front of your camera, or just any movement to check if it works. If the system has been set up correctly, images should be saved in the storage folder that you specified when you were setting it up. If it does not work, double check everything until you are sure that you have correctly done the basic steps to turn your personal computer into a motion detecting system.

This article discusses the basic way for one to make use of the personal computer as an equipment for motion detection, more details may be needed in order to transform it to an advanced motion detection system. However, it is still recommended to use a device that has been purposely designed for motion detection. You can visit SafeSecure24 or Strongman Security for more about a motion detecting system.

The extraction layer is the collection of data from source systems. It aims to secure the integrity of data while eliminating reporting problems on the source systems. Data can be extracted from an array of different sources.

SAP NetWeaver BW offers predefined, customizable extractors for application data from the entire SAP Suite. You can also design extractors for customized SAP applications. Most extractors for SAP application transaction data are delta-enabled, which translates to mean that transactions can be written to a delta queue at the time of submission. They are then extracted from this delta queue into SAP BW.

Direct extraction from databases based on table or view definitions using DB Connect and UD Connect extraction interfaces. DB Connect (Database Connection) permits the extraction from and direct usage of data lying in tables or views of database management systems. This feature is available primarily for some specific databases. UD Connect (Universal Data Connect) permits the extraction

from and direct access to both relational and multidimensional data.

Web services allow you to push data to the SAP BW system with external control.

Flat file interface allows extraction from flat files in ASCII and CSV format.

Staging BAPIs (Staging Business Application Programming Interfaces) are open interfaces from which third-party tools can extract data from more aged systems. The data transfer can be triggered by a request from the SAP BW system or by a third-party tool.

Data is acquired from SAP BW using a pull mode, through objects called InfoPackages. Options for the data acquisition can be set in the InfoPackage.

B) Staging layer:

Extracted data is received and temporarily stored in the staging layer of SAP NetWeaver BW. The data staging layer stores source data from different operational sources. When data is inside of the staging layer all needed transformations can then occur without interfering with the operations in the source systems. Data is also preprocessed for purifying before calculation and/or aggregation based on business requirements. This layer is mostly represented by the persistent staging area (PSA), where data is stored in SAP BW just after it's extracted. The technical structure of a PSA relies on the structure of the DataSource.

C) Transformation layer:

The transformation layer of SAP BW facilitates the consolidation, cleaning, and integration of data into the warehouse. Data gets reworked from the source format into the desired destination data format. Data transformation can include data mapping and formulas.

D) Loading layer:

The actual process of pushing data through the transformation layer into the data targets. A data transformation process (DTP) transforms the data based on the parameters determined between the DataSource and the data target.

E) Reporting and Analysis layer:

Within the reporting and analysis layer, reports and dashboards are put together to display data in a format where analysis can be done. The components that embody the reporting and analysis layer are organized together in the SAP business explorer (BEx) toolset and more recently the Business Objects toolset.

Laptops for 2011

ByGeoff Wheeler

If you are in the market for a portable computer, and we can call them all laptops, then your choice really comes down to one of three types: a tablet, a netbook or a small laptop.

While it is getting more difficult all the time to tell the difference among them as they borrow features from each other and are constantly upgrading, let's look at what you get with each of the three basic types.

A tablet comes with a 7 to 10 inch screen and is the ultimate personal browsing, reading and entertainment device. With a touch screen you have access to apps, you can read a book or a magazine, and this unit is extremely light and thin for easy portability. In fact some will even fit in your pocket. And unlike the other two options, the tablet will turn on almost instantly.

The Apple ipad is the tablet to beat, with Motorola's Xoom and the Samsung Galaxy Tab coming in a close second. As long as you do not need to do any heavy typing or organizing complex projects, this may be the machine for you. Tablets are priced in the $500 to $700 range, weigh in at about 1.5 pounds and have a battery charge life of 9 to 12 hours. Most have internal storage of up to 64 GB.

The next size up is the netbook, usually coming with a 10 inch screen. This machine comes with a physical keyboard and Windows 7 installed and is ideal for creating and editing longer documents on the fly and at a cost much less than a full-sized laptop. Most netbooks do not have a touch screen, but come with up to 250 GB of internal storage. Netbooks are priced in the $300 to $500 range, less than a tablet or the larger laptops, and will weigh in at around 3 pounds with a battery charge life of 8 to 9 hours. If you are looking for a small work machine, then a netbook is a good way to get going.

The 3rd option is a smaller laptop which will have an 11 to 13 inch screen and is for those wanting greater processing power and storage ability. With a full keyboard but no touch screen, these devices weigh in at 2 to 5 pounds. They are larger and thicker than the tablet and netbook,give you in excess of 300GB of storage and are priced in the $700 to $1200 range. If you need more apps and software for your work and are not concerned with minimal size and thinness, then the smaller laptop is ideal.

So in summary, for entertainment and extreme portability, the tablet is your choice today. For more serious applications and work, you can choose between the netbook and a small laptop, depending on the complexity of your work requirements.

Having chosen among 3 types, your next problem will be the number of brand and generic products out there that will make you selection more difficult. But in the end, considering what you are getting, they are all tremendous machines and today's bargain prices make it increasingly easy on your wallet!

Geoff Wheeler has been involved in freelance writing for the past 4 years and enjoys writing about laptops for kids including his article for the One Laptop Per Child Program

Thin Film Flexible Solar Panels Are The Soon To Be Future Of Personal Solar

There is soon to be an unprecedented convergence of personal technologies that is going to change the way people work and use their personal electronic devices. Up until about a year ago, people hadn't ever really heard of creating private hotspots for wireless internet access. The technology existed, but was generally pretty costly. Recently though, it's becoming extremely popular and widespread. This recent breakthrough, combined with personal, portable solar technology, is going to change how people use their personal electronics and where and how they work.

What's personal solar technology anyway? The newest breakthroughs in solar technology have manufactured solar panels that are very thin, light, flexible, rollable, inexpensive, and portable. Personal solar pads have been manufactured that seek to give users the ability to charge their personal electronics while outdoors in the beauty of nature. This includes devices such as iPones and iPads, laptops, GPS, and more. Some of the most recent personal solar products have impressive wattage outputs and can be rolled up or folded up to fit nicely in bags, purses, and other small spaces. They can keep your electronics operational and charged, even while in remote spots in nature.

Personal solar panels, when combined with personal hotspot devices is a very powerful combination. Never before has a person had the ability to trek out into nature and not only have internet access, but also be able to keep their devices charged. People are growing tired of overcrowded cafes and slow web access. Once they realize that for not a whole lot of money, they can be out in the beauty of the great outdoors, lounging on a park bench while they work, they'll think twice about continuing to deal with the lines, noise, and hassle of working at a cafe. And when you actually take a look at the price breakdown, you might even discover that going the way of personal hotspot and personal solar charging pad might actually be more cost effective than traditional methods.

Perhaps the greatest part about these two technologies is that they actually have the ability to save you a lot of money in the long term. A few of the more inexpensive brands in personal solar panels actually cost less than a hundred dollars. Though these might not quite have the electricity to keep all of your gadgets charged throughout the day, the more expensive and more powerful brands are still only a few hundred dollars. Thin film, flexible solar panels are starting to come down quite a bit in price. That means that when you factor in the money saved by not needing to order a cup of coffee from the cafe, not needing a subscription to a home based wireless web service, and not needing to keep the lights on in your home and not needing your home to charge your laptop, you could be seeing quite a lot of savings. Beyond that, you also receive the added bonus of being out in the beauty of nature and away from crowded coffee shops. It takes a little bit of effort to make the switch to personal solar and personal hotspot devices, but when you do, there's really no reason to turn back.

There are a variety of great new brands of personal solar panels. The Goal0 Nomad is a great starter pad. If you need more power though, you might want to have a look at the Brunton 14 Watt Solarroll.

Improving Video Over Wireless Network Performance

ByShaun Hummel

Overview

This article discusses how to improve video over wireless performance. Many companies are using various new video content technologies today such as live video streaming, webcasting, video conferencing and web conferencing. YouTube services continue to be popular and are using increasingly more bandwidth as companies use video for training and marketing purposes. Google language translation service can now convert text, making the English text based videos available to other countries as well. Keep in mind that with the proliferation of company VPNs for security purposes, employees can use wireless at work as seamlessly as at home or on a public network. They can access the same video services from anywhere. This is why wireless is so popular now and the need for video grade wireless infrastructure performance.

The current 80.11a/g wireless access point is easily swamped when several clients start downloading large files and running video applications. The best solution for guaranteeing acceptable video performance is now the 802.11n wireless standard. According to a Cisco forecast study, the number of wireless devices will exceed wired devices on the internet by 2015 and account for 54% of IP traffic. In addition video traffic will account for 90% of the consumer internet traffic by 2015.

Video Basics

Video and voice are real-time traffic streams by nature that are sensitive to network congestion that causes latency (delay). Video has both a data and an audio component. It should be noted that the same performance metrics such as jitter, latency, packet loss and throughput affect video as well as voice traffic across the internet and company network. Packet loss has a greater effect on video while latency affects voice much more. Guaranteeing specific service levels for video on the network could involve implementing QOS, increasing network bandwidth, network design changes and equipment changes. All these improvements are for the purpose of making the network "video ready". Companies increasingly use web conferencing, webcasts and video conferencing for meetings and for training purposes. Colleges use it to deliver courses as well. It is a very cost effective tool to decrease company travel costs.

Types of Video

It is worth discussing the various types of video services popular today and where, from a networking perspective, consumers source the content. Note how most of the services are across the internet.
Live Video Streaming over the internet of company Webcasts and TV broadcasts typically delivered to your desktop.Web Conferencing to the desktop with applications such as Skype and the very popular Go to Meeting service.Video Conferencing service that runs from and across the company network with Cisco Telepresence and equipment from companies such as Tandberg and Polycom.Progressive Video download from companies such as YouTube to the desktop.Broadcast Video multicast of one to many video streams such as Netflix.

Video Performance

H.323 defines a suite of protocols for audio and video traffic including H.264 and G.729 protocols. It is a framework for developing multimedia applications on a company network. The G.729 protocol is a popular audio codec for compressing audio traffic at 8 Kbps with a 10 ms delay. The H.264 video codec standard is the most current adopted video compression standard. It specifies 24, 30 and 60 frames per second (fps) for high definition (HD) video conferencing with compression from 1.5 Gbps of video traffic to 4 Mbps at a resolution of 1920 x 1080 and 30 fps.

It is important to understand the performance metrics that affect video performance including packet loss, latency, jitter and throughput. Video is sent as a constant stream of traffic in contrast to data traffic such as email that can be re-transmitted with some delay and have no significant effect on service level. Congestion is the basic symptom of a network that is busy and experiencing network performance problems. The queues are busier during times of increased network activity. This causes increased latency, jitter, packet loss, decreased throughput and re-transmission of packets. Implementing quality of service (QOS) will sometimes actually cause dropped data packets to prevent voice/video packet loss. The data packets are then re-transmitted with some delay. The following defines these industry standard performance metrics.

Latency: Amount of time for a packet to travel from source to destination

Jitter: Amount of average variation in latency of each packet

Packet Loss: Percent of packets dropped from source to destination

Throughput: Average number of packets sent during a fixed period of time

Each video service requires different amounts of bandwidth. Some services such as video conferencing are more affected by increased latency, packet loss and jitter than desktop applications. For acceptable video conferencing performance, the packet loss should not exceed 1%, jitter 30 ms and a one-way latency of 300 ms (latency of 150 ms for high definition video conferencing resolution). When these thresholds are exceeded the picture can deteriorate. Bandwidth requirements for video are linked to the specific type of service, amount of resolution and frames per second. For example a standard video conferencing resolution of 704 x 576 at 30 fps requires 768 Kbps - 1 Mbps of bandwidth while a High Definition (HD) resolution of 1080 x 1920 at 30 fps requires 4 Mbps - 12 Mbps. Desktop services such as streaming video and web conferencing have lower bandwidth requirements than video conferencing, however the same latency, jitter and packet loss problems affect video performance. In addition with all services, you have to add an average of 20% additional bandwidth overhead for Ethernet and IP protocol processing.

Video Quality of Service (QOS)

Implementing quality of service (QOS) on a company network is an end to end process starting with the video stream source. Video conferencing end points are often connected to a company edge switch while video streaming to the desktop is internet based. The process of implementing any QOS involves prioritizing traffic for preferential service. Considering video conferencing, the Cisco 3560 and 3750 access edge switches are often used to connect video equipment. The layer 2 data frame has an 802.1p header with 3 bits that can be set for 8 different class of service (CoS) values from 0 - 7. For instance video is assigned CoS of 4 while voice packets are assigned CoS of 5 and the higher number gets better service. High priority data is often assigned CoS of 2.

DSCP is a layer 3 QOS protocol used to specify various types of service (ToS) classes for data, voice and video traffic. DSCP values are layer 3 and as such are set in the first 6 bits of the IP Precedence field of the IP header. The best practice recommendation from Cisco for marking video is a DSCP of AF41. Data traffic is assigned a lower priority such as AF21 for instance while voice is assigned a higher priority of DSCP EF. Video traffic is classified with access lists that define video traffic and a class map is defined for video that matches an access list and points to a specific policy map. The policy map does the DSCP marking of video traffic and the DSCP value is assigned to a queue. Class of service (CoS) packets can be set with a policy map however it is often marked at access switches with SRR and with WRR at distribution/core switches.

Shaped Round Robin (SRR) is a hardware based queuing technique deployed with access switches. SRR allows layer 2 class of service (CoS) and layer 3 (ToS) mappings to queues. The distribution and core network layers typically have 6500 Cisco switches and they use Weighted Round Robin (WRR) hardware queuing. WRR is the same idea however the queuing architecture is somewhat different and only layer 2 class of service values are mapped to queues.

WAN routers are deployed with Low Latency Queuing (LLQ) and Class Based Weighted Fair Queuing (CBWFQ) that assigns video traffic to the high priority queue with a specific priority percentage such as 15%. That guarantees all video traffic will get 15% of the link bandwidth. For instance a 1 Gbps Metro Ethernet circuit will allocate 150 Mbps of bandwidth to video traffic minus protocol overhead. Company WAN links as a best practice should never exceed approximately 33% of available bandwidth for all voice and video traffic. That leaves room for protocol overhead and data packets. Data traffic performance worsens as packets are dropped and video traffic QOS becomes less effective.

Desktop applications use the same QOS tools however the company internet connection and the wireless network factor into the design. In addition the public wireless network you happen to be using affects the overall video network performance. The bandwidth of your home internet connection and congestion affects performance as well as any congestion points across the network. The wireless network is most often where video performance degrades particularly on an 802.11b public network.

Wireless Standards

These describe the industry standard wireless protocols currently deployed.

80.11b

This wireless standard approved in 1999 specifies a maximum data rate of 11 Mbps using the 2.4 GHz unlicensed band in the United States. The band experiences a lot of interference from commercial devices using that frequency. The standard in the United States assigns 11 channels with bandwidth of around 80 MHz at 5 MHz per channel. The United States allocates 3 non-overlapping channels of 1, 6 and 11 with a center frequency separation of 25 MHz per channel. The modulation scheme used with 802.11b is Direct Sequence Spread Spectrum (DSSS) with CCK with characteristics that minimize effects associated with interference. The 802.11b additional data rates include 1, 2, and 5.5 Mbps.

802.11g

This wireless standard approved in 2003 specifies a maximum data rate of 54 Mbps using the same 2.4 GHz band as 802.11b. The 802.11g standard is popular with higher throughput and increased coverage. The same interference problems occur however with the 2.4 GHz band. The 802.11g is compatible with the 802.11b standard and assigns the same 11 channels with 1, 6 and 11 as non-overlapping. The modulation scheme used with 802.11g is OFDM that specifies higher data rates. The additional 802.11g data rates include 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36 and 48 Mbps.

802.11a

This wireless standard was approved in 1999 specifying a maximum data rate of 54 Mbps using the 5 GHz unlicensed band in the United States. The advantage of 802.11a is higher throughput however the cell coverage is smaller and additional access points will be needed for the same 802.11g coverage. There is much less interference from devices such as cordless phones, bluetooth devices, microwaves and commercial devices using the 2.4 GHz band. There are 23 non-overlapping channels with the current 802.11h specification. Some Cisco devices support both 2.4 GHz and 5 GHz transmitters on the same access point. The modulation scheme used with 802.11a is OFDM, with higher data rates and minimizing effects of interference. Each country specifies the number of channels and frequencies it allows with the 5 GHz band.

802.16

This is a metropolitan (MAN) wireless standard that provides home and business clients seamless wireless access from anywhere. The line of sight technology specifies a distance of around 27 miles and speeds of up to 120 Mbps. The point to multipoint specification operates in the 10-66 GHz range. There is an 802.16a specification with mesh topologies and non-line of sight with frequencies from the licensed and unlicensed 2 GHz and 11 GHz band at a speed of 70 Mbps. The key problem with any MAN implementation using unlicensed frequencies is interference from similar devices.

802.11n

The new 802.11n wireless standard approved in 2009 defines much faster data rates of 300 - 600 Mbps and 1000 Mbps from access point to network switch increasing throughput from client to access point and access point to network switch. It operates in both the 2.4 GHz and 5 GHz bands with effective new performance enhancements such as multiple input multiple output (MIMO) and channel bonding.

Wireless Contention

Access points are essentially a less efficient hub style shared media device with a flat broadcast domain. Contrast that with a Cisco Ethernet switch that has 100/1000 Mbps bandwidth per port and broadcast segmentation with VLANs. The switch uses a much more effective media access contention scheme than wireless access points. The wireless network employs an older less effective carrier sense multiple access with collision avoidance (CSMA/CA) process to manage client access to the network. The effect of CSMA/CA is increased bandwidth usage, packet loss and packet re-transmits with this shared media. In addition there are the standard wireless problems with the 2.4 GHz band interference and multipath signal fade that occurs when the signal bends or is distorted by the building structure. From a practical perspective 15-25 wireless clients can associate with a single access point at anytime and still maintain good performance. This of course changes as more video and high bandwidth applications are used. The 802.11n can actually support all of those clients running simulataneous live video streaming with 14 of them running high definition video streams.

Data Rate, Distance and Frequency

So by now you know there is no warp speed with older wireless. Data rate (speed) and performance metrics decrease as the wireless clients move further from the access point. Beyond an average of 50-60 feet, the speed decreases and latency, packet loss and jitter increase. The wireless network site survey determines where and how many access points should be deployed so each cell (defined coverage area) has a signal strength with 54 Mbps. The coverage area can be extended with a stronger directional antenna. For instance, these are approximate rated distance, speed and frequency specifications indoor for the Cisco 1240AG access point. Note the 802.11a distance is typically half that of an 802.11g radio however this rating was with a stronger 3.5 dBi antenna.

802.11a (5 GHz): 54 Mbps

Using Digital Photo Frames As Wedding Decorations

Many people use photos to decorate their wedding venue, but in this digital day and age, you can use digital photo frames to create unique, fun wedding decorations. A digital photo frame features all of your digital photos in a familiar format, and now you do not have to use your computer to enjoy your digital photos. To get the photos onto the frame you generally have to use a SD card or a USB drive. Some of these frames can even play movies and music to accompany your photos, and most of them will play slideshows.

At the Church

While you will not have too many decorations at the ceremony besides the flowers, you can use a digital photo frame in the church. One of the best places to put it is by your guest book. This way people can see pictures of you and your significant other when they sign their name and leave you a message. While you can use these frames at the church or the site of your ceremony, they are probably better suited as reception decorations.

At the Reception

At the reception, you can be really creative with your decorations. If you want to use a lot of digital photo frames, you can place one at every table. This will give people something to talk about while they eat, which is especially good if your families do not know each other that well. You can put the same photos on every frame, such as photos of you and your new spouse. However, you can also put different sets of photos on each frame. For example, one frame could be the groom as a child, one frame could be the bride as a child, one frame could be of the happy couple, and so on. If you do this, it gives people a chance to visit the other tables to talk to people and see the different photos.

The great thing about digital photo frames as decorations is that when the wedding is over, you can use them as gifts for your parents, your bridesmaids, and your groomsmen. You can prepare personalized sets of photos for them and give them the frame that night after the wedding or the next day. If you are thinking about using these frames at your wedding, it is a good idea to go ahead and invest in some good ones. While you can find very inexpensive frames, you will want these memories to last.

How to Safely Clean Laptop Keys

OK, so the other day you spilled a bit of soda onto your new laptop keyboard, and the next day arrives and some of the laptop keys do not come back up when you press them down. That is no big deal. There is no reason to send your laptop away to have its keyboard replaced. It can cost $50 to have a laptop's keyboard replaced. All that is needed to clean them are a few household items.

Disclaimer: I am not responsible if you incorrectly pop off and break the mechanism under your keyboard keys ending up with a broken computer. Some keys, mainly the non-square ones, are trickier to get off and are sometimes not as simple as just "popping them off" because they have metal prongs or clasps.

Materials Needed:

1 cue-tip per couple of keyboard keysglass of watera small thin object used as leverage to pop off the laptop key (pocket-knife, car key, etc)

Directions:

Make sure your computer is off when working with the hardware. Normally, pouring liquid onto just your keyboard is not that harmful, but since it is a laptop, the liquid could seep into more important components of your computer and cause harm to your computer and possibly yourself.Take the pocket-knife and wedge it in between the sticky key and the base of the keyboard. Your fingernail can also be used as a wedge of it is long enough. Mine are not. You can pop off and clean more than one at a time, just be sure of the keyboard's layout so you do not get confused when replacing the laptop keys.Lift up with the pocket-knife and pop off the key. It might take a little more force than you feel comfortable with, but that is OK. Most keyboard keys are fastened kind of tightly by two very small pieces of plastic and 2 indentations in the key socket. They also tend to be much flatter than a normal desktop keyboard's keys, hence the need of a pocket-knife.Touch the end of a cue-tip to the water ever so slightly. You just want it to be damp - not dripping. Fun Fact: Most electronic devices will be fine if you splash water on them as long as they are completely dry before power is turned back on.Use the cue-tip to clean the underside of the laptop key, the laptop key socket, and the area directly around the socket. The cue-tip makes sure that you lift up all of the stickiness that might be hiding in small places.Replace the key you just cleaned, and press it a few times to make sure it works properly.Repeat steps 5 and 6 until your laptop no longer has sticky keys.

Some keys can simply not be saved, especially if they are broken computer keys because of excessive use and not because of poor use. Replacement laptop keys are typically easy to find online and do not cost more than a couple of dollars per key.

Solar Backpacks Are A Handy Technology For Those On The Go

I like the idea of solar backpacks, having the ability to not only transport your personal electronic devices, but also being able to charge them on the go. For the most part, this technology isn't super viable, just because of the fact that the solar panel on the majority of solar backpacks doesn't cover a very large surface area. That being said, there are a couple of big name brands that manufacture a very nice quality backpack, and even generate an impressive 5 watts of power. 5 watts is not really enough power to keep all of your personal electronic devices fully charged, but it can definitely generate a fair share of energy over a couple of hours of direct sun.

The one thing I like the most about solar backpacks is that they're not too much more money than regular backpacks. One brand for example, Samsonite, which produces some of the best quality packs and carrying cases, also makes a solar backpack with a big solar panel woven into the back of it. A good quality Samsonite pack without a solar panel would already run you around $100, but with the solar panel included, it's only $135. So you aren't really paying much more for the solar feature included. Even if you can't see an immediate way to use the solar panel, it's always nice to have the feature available for those just in case moments when you're on the go.

But for real usability, it's still only really worth it for people of pretty specific situations. Most people don't spend near sufficient time in the sun to make a solar backpack worth their time. College students and backpackers are probably the only big segment of the population that could make full use of a technology like this. Businessmen who always find themselves on the go could probably also make use of this technology, but the rest of us who spend 8 hours a day at a desk right next to an electrical outlet, we don't generally need a technology like this.

But personal solar panels are really beginning to alter the way that people do outdoor adventures. One activity specifically, Geocaching, makes great use of portable solar technology. Geochaching, for people who don't know about it, is basically a blend between backpacking and treasure hunting. Most geocachers use GPS and other little gadgets to get the job done, and like having the ability to power them while on the go. Another outdoor adventure that portable solar is changing is boating. Peel and stick solar technology are showing up on boats all across the nation. It's pretty neat.

While these panels are great the big issue with solar backpacks is that they just don't generate enough power to make them very viable. That's why many people who use portable solar technology, purchase a flexible solar pad or some brand of peel and stick solar. These tend to produce more power and are pretty handy for most outdoor activities. These technologies is a bit more costly, but they really get the job done.

Why Tablets Are the Future of Computing

You may have even about tablets being slated to storm the market in the coming years. Many analysts and forecasting companies have already announced them as the next big thing in the world of computing. According to them, tablets will soon outsell netbooks, a form of portable computers that instantly became popular in 2009, resulting in millions of units being sold.

Now that the craze of netbooks finally seems to be getting over, but consumers still preferring to get hold of some form of portable computers, tablets have a great chance of becoming the most widely used form of computing in the next 5-10 years. The only downside to them, that one could think of is that they don't probably match up to personal computers, desktops in particular when it comes to the specifications, since they are only useful for a net-savvy person who spends most of his time online researching information and browsing the web, or occasionally chatting with a few friends as well. Tablets usually come with only 1GB RAM and upto 32GB storage, though some of the latest ones allow you to expand the memory to 64GB via a MicroSD card slot provided in them. But still if you compare them to laptops or netbooks, they are way too behind.

Though tablets may be suited for the average computer user, they are obviously not good enough for gaming or heavy documentation work. But the reason they have taken the market by a storm is not because of their limited features, but because of their mobility. Laptops usually weigh around 6-8 pounds, which is heavy enough for anyone to conveniently carry them anywhere. Netbooks, on the other hand, started selling like hot-cakes only because they weighed almost half of that, somewhere in the range of 3-4 pounds or even less.

But now that spectacular looking tablets that have an incredibly light weight have arrived on the scene, it is almost guaranteed that they are bound to succeed. Plus users also get to enjoy the power of touchscreen, which means they have on-screen keyboards instead of physical ones that now sound outdated. Finally, coming on to the price, this is where tablets seem to clinch the deal. Most of them are available in the markets in the range of $300-$400, and some of them even cost less than 200 bucks, which is incredible considering the value they provide. And with major manufacturers now about to come up with their latest low cost tablets, the device may become even more popular.

Choosing an Effective Surveillance Camera System

Many activities happen in most places in a city. Different exchanges of activities transpire everyday in business establishments, schools, hospitals, streets, offices, and homes among others. Most often than not, these activities are often delayed or impeded with various crimes. These crimes include burglary, traffic violations, or even murder. Thus, the normal flow of activities is interrupted as crimes get in the way.

This is one of the most common reasons why many people are opting to install a surveillance camera system in their homes, businesses, offices, and other places where they conduct their everyday activities. Police departments likewise use security surveillance cameras to spot crimes such as over-speeding, robbery, and other threats to security. Security cameras systems are considered non-lethal tools that can stop criminals from doing their thing.

Setting up a surveillance camera system allows passive observation of the things happening around your area. Most often than not, surveillance cameras include infrared detectors, motion detectors, and ultra-sensitive microphones. Some people choose to connect their security cameras or surveillance cameras to a nerve network center of a police station so that response can easily be rendered in case a crime happens in their areas.

For a larger scope of surveillance, some people set up CCTV camera systems or security camera systems in strategic places within their vicinity. Operators of these security systems are able to call for help as soon as they observe a crime. Thus, police officers are able to arrive as quickly as they can to respond to the scene of the crime. Security camera systems are all capable of recording images and sounds, which makes them useful as evidence for proving a crime or convicting criminals.

When choosing to set up surveillance or security systems, you should consider several important identifiers. You should remember that criminals usually attack when the situation is perfect for their plans. However, if they are aware of the cameras in their target area, they tend to leave for fear of being caught in the video for evidence. Thus, you should set up your surveillance cameras in places where they are visible to people.

For most business establishments, announcing the presence of their CCTV systems works as criminals or lawbreakers are stopped from doing their unlawful acts. Criminals or lawbreakers do not want to get caught or taped in videos while doing their stuff. In fact, the crime rates for areas that announce the presence of their CCTV systems are much lower as compared to those that hide their surveillance systems.

As much as possible, it is preferable to install or set up surveillance systems near the vicinity of policemen. This is to quicken the response rates of police officers as well as apprehend criminals as quickly as possible. If the operators of the surveillance systems are trained enough, they will also be able to determine the number of police officers needed to respond to the crime. The operators can also guide the policemen on how they can act upon the crime.

Fiber Optic Cable Types: Simplex Vs Duplex - Singlemode Vs Multimode

ByCaleb Chao

When purchasing either a fiber optic HDMI extender or VGA extender, it is important to understand the different varieties of core characteristics that are available within the cabling itself. Each of these different characteristics will have different effects on your ability to transmit information reliably, and these different characteristics also affect how the extender or VGA extender you are looking at will cost. Let's take a look at the most common fiber optics cores used in the industry today.

Simplex

Simplex fiber optic cables consist of just one optic fiber. Their purpose is in one-way signal transfer applications. Analog to digital data readouts, interstate highway sensor relays, and automated speed and boundary sensors (for sports applications) are all great uses of Simplex fiber optic cable. This form of fiber cable can be cheaper than Duplex cables, because less material is involved. Simplex cable is compatible with any HDMI extender.

Duplex

Duplex cable is simply two optic fibers structured in a zipcord arrangement. Zipcord style means the cables run next to each other. Multimode and Singlemode duplex fiber alike are used for two-way data transfers. Larger workstations, switches, servers, and major networking hardware tends to require duplex fiber optic cable. Duplex cables can be more expensive than Simplex cables, and are compatible with any extender.

Singlemode Fiber Optic Cable

Singlemode fiber has a smaller core and just one path for light to travel down. Since there is only one wavelength of light moving through the core, single mode light aligns at the center of the optic core rather than bouncing about the interior of the core, which is the technology that enables Multimode cable to carry multiple light signals. Singlemode cables might be used in conjunction with a long range extender, or perhaps a few extenders, to move fiber optic signal over multiple miles. Singlemode fiber tends to have a glass core at 9-micron, and is compatible with either a one-way or two-way extender or VGA extender.

Dualmode Fiber Optic Cable

Dualmode fiber is a large diameter fiber core. Due to its relatively large size, multiple channels of light can be transmitted, allowing multiple bandwidths and signals to be transmitted simultaneously. Dualmode works great for most fiber applications. It works especially well in alarm systems, audio/video systems and production, desktops and laptops, and display systems. Dualmode fiber cable is both HDMI extender and VGA extender compatible.

Cable Thicknesses

Optic fire cable thickness can change depending on if your application calls for an HDMI extender, VGA extender, or both. The average HDMI extender will typically be used in conjunction with a 50 micron cable as opposed to a 62.5 micro cable. The reason an HDMI extender is used with 50 micron cable is because it has three times the bandwidth as compared to a 62.5 micron cable. Thus since an HDMI extender is typically used with two-way HDMI communications, you will rarely see an HDMI extender in use with a 62.5 micron cable.

For the past decade, Avenview has established itself as a quality manufacturer of leading edge Audio/Video products such as the fiber optic HDMI extender and the optic fiber VGA extender. Avenview leverages scalable, powerful, and advanced video processing capabilities with proven reliability that harnesses integrated extension, distribution and conversion technologies to win customers for life.

What Is Disk Defragmentation?

ByFateh Kumar Singh

There is a utility given in the Microsoft Windows named as Disk Defragmenter which is designed for maximizing the access speed, it rearranges the relevant data files stored on the disk for occupying associated storages. This process is known as defragmentation. It can be describes as the process of consolidating the fragmented files which are on the PC's hard disk.

This process happens on the hard disk when you save, change or delete any file. When you make any changes to a file they are stored usually at the location which is different from the original file location. With time the file and the hard disk both are fragmented and the computer speed slows down because it looks in different paths and location to open the required file. It can be done for computer maintenance work as many firms offer this service.

It is a tool which rearranges data from hard disk and then combines them into fragmented files. It makes your computer to run more conveniently. With this Windows version it runs with a predefined schedule and you don't need to run it again and again but its schedule can be changed. Since it is a tool and also used as a service most of the PC maintenance services providers use it. We can check the process of disk defragmentation as follows:

a) Firstly click the Start Button, in the search box type it and click on it from the given results.
b) A box will open showing the different disks, click on the disk you want to defragment.
c) First check whether the disk should be defragmented or now click Analyze disk. If it required for an administrator password provide the confirmation.
d) When it finished analyzing the disk you can check the percentage of the fragmentation in the last run column. The disk can be fragmented if the percentage is above ten percent.

It might take some minutes to hours to complete the process and it depends on the size of the disk as well as the number of the fragmented files. If any volume is not to displaying in the select disk dialog box and it has to be defragmented then it should be done manually.

It is an important work that must be done at a regular interval in order to prevent the risk of complete system failure or physical damage to the hard drive.

Definition of a Business Analyst

ByPreeti D G

According to Dictionary.com website a Business Analyst (BA) analyze the organization and design of businesses, government departments, and non-profit organizations. BAs also evaluate business models and their integration with technology.

Fundamentally, the responsibilities and activities performed by a business analyst are varied, but the most significant objective is always to advance the communication between the stakeholders and the project developers. Business analysts become more successful when they have undergone appropriate requirements training that educate them how to become efficient communicators and how to gather and write the requirements of the stakeholders.

Business analysis has four tiers. These four tiers consist of planning strategically,operating or business model analysis, process definition and design and the technical business analysis.

LEVELS:

There are at least four tiers of business analysis:

Planning Strategically - The analysis of the organization's strategic business needs of the organizationOperating/Business Model Analysis - The BA definitions and analyzes the organization's policies and market business approachesProcess Definition and Design - In this level tier refers to the business process modeling (often developed through process modeling and design)IT/Technical Business Analysis - The BA assists in the interpretation of business rules and requirements for technical system

As you can see, there are a number of characteristics which identify the role of the Business Analyst including:

The analyst works with the business to recognize opportunities for enhancement in business achievements and procedures.The analyst is involved in the design or modification of business systems or IT systems.The analyst interacts with the business stakeholders and subject matter experts in order to understand their problems and needs.The analyst gathers, documents, and analyzes business needs and requirements.The analyst solved business problems and, as needed, designs technical solutions.The analyst documents the functional and, sometimes, technical design of the system.The analyst interacts with system architects and developers to ensure system is properly implemented.The analyst may help test the system and create system documentation and user manuals.

ALTERNATIVE DESCRIPTIONS

We proposes the following : "An interior consultancy position that has responsibility for inspecting industry structures, identifying opportunities for humanizing business systems and correlating the desires of the business with the use of IT." The International Institute of Business Analysis (IIBA) describes the role as: "a liaison among stakeholders in order to understand the structure, policies, and operations of an organization, and to recommend solutions that enable the organization to achieve its goals." The Certified Software Business Analyst (CSBA) Common Body of Knowledge defines this as: "uniquely placed in the organization to provide a strong link between the Business Community and Information Technology (IT)."

The role of Business Analyst has evolved from someone who was a part of the business operation and worked with Information Technology to improve the quality of the products and services being delivered by the IT organization to someone who apart from gathering Business Requirements, also assists in Integration and Acceptance Testing, supports the development of training and implementation material, participates in the implementation, and provides post-implementation support. Business Analysts today are also involved in the development of project plans and often provide project management skills when these skills are not available in other project participants.
