Cheap RAM

December 7th, 2006

By Ken Marlborough

The cheapest type of RAM is dynamic RAM because it uses traditional technology as opposed to static RAM, which is expensive and uses advanced methods to store and retrieve temporary information. Dynamic RAM has capacitors that act like vessels that store temporary information for the CPU to use as and when required. This makes them cheaper as compared to static RAM that is expensive because it does not use the same technology as a dynamic RAM.

RAM chips are available in the market within a price range of $4 to $400, depending on its make, brand, upgrade, and type. The modern computer usually uses dynamic RAM that is at least 128 MB in size. This RAM race started in the 1990s when 2MB of RAM were used. However, technology has improved in leaps and bounds since then, and today using less than 128 RAM would be not advisable, as the speed and efficiency of the computer will be dramatically affected.

SIMM RAM is the oldest and cheapest of them all but can only be used with old machines and is not compatible with newer ones. It is available for less as $5 and can be bought on the Internet. A memory upgrade is the most cost effective method of improving a PC’s performance, and memory upgrades are very simple to install and require no configuring at all.

A 4 MB 30pin 60ns 3-chip SIMM RAM with a tin lead and a 2-piece 2 MB x 8 chip and logic parity is priced at $7 to $8, whereas a Cisco 16 MB Catalyst 8000 Flash SIMM can cost up to $89. The price of a RAM chip depends upon the number of nanoseconds, the brand, type, megabytes, and other such factors. The price of RAM also depends upon the type of computer that a person uses. This is because an older computer will usually use a 2 to 8 MB RAM, but a newly bought computer will need a 128 MB RAM in order to function efficiently.

How To Choose The Best Big Screen TV For You

December 6th, 2006

by: Jon Arnold

There is nothing more gratifying than owning an impressive home theatre system. The booming speakers. The magnificent picture quality of the gigantic television in the center. Even the comfy couch adds to the ambience of the room. The cost is worth it for those that know how to do it right.So how does one go about getting the most bang for their buck?

The current options are daunting. Flat screen. Plasma. LCD. DLP. What do all these things mean? Lots.

Let’s start with the oldest. When projection televisions first came out years ago they were looked at as the next big thing. They offered a larger viewing screen than was possible with the traditional tube television. They range in size from 42” to 65” and beyond. Using three different colored tubes, red, blue and green, rear projection TV’s can provide a startling amount of clarity. But the quality of picture can vary depending on seating arrangement. This is seen as a great detractor to projection TV’s.

Another difficulty lies in the tremendous bulk with these TV’s. They are the least advanced of the current TV’s although they now come in a microdisplay variety. For a fraction of the cost of the other newer technologies, a consumer can get a quality set with the purchase of a projection screen TV. For those on a budget, this is the best choice for a big screen.

Speaking of those other, more advanced televisions, let’s look at plasmas and LCD screens. When plasmas first hit the market they were priced at very high rates, some going for over $15,000 MSRP. Times have changed but the prices for these TV’s are still at the higher end of cost. A plasma screen is actually a network of tiny individual pixel cells infused by a rare gas mixture. Because of this incredible technology, plasmas are considered by many enthusiasts as the clearest picture around. However, their prohibited cost and a potential “burn-in” problem may cause concern for some buyers. But these TV’s are truly phenomenal for the avid purchaser being sleek and thin, normally 4” in thickness. They range from 40” to 70” in size.

LCD stands for Liquid Crystal Display. The technical definition is transmissive technology uses a light engine to stream high-intensity white light onto the screen. The more layman’s reference would be like the display on the majority of laptop computers. LCD screens are amazingly bright, the best to view in dark lighting conditions. This brightness can come at a price, however, when certain images suffer from blurriness. They range from 10” up to 37” in diagonal length. Just like the plasmas, they are light enough to be mounted on any wall.

Another option you will have is whether to go with the 4:3 aspect ratio or the more popular 16:9 or “wide” screen format. In other words, the 4:3 aspect ratio is more like a traditional TV, whereas the wide aspect ratio is gaining tremendous popularity. This is the size of the screen that you see in a movie theatre. The movies you rent at BlockBuster or your favorite video store show in this wide format by default and look significantly better in a wide format TV than trying to “squeeze” the DVD onto the older 4:3 aspect ratio screen.

In this day and age there are many choices in home theatre systems. Weigh the pros and cons of each. If the room is large and seating good for all viewers, perhaps projection is the way to go, although you still need to consider the viewing angle. If the space is limited, go with the flat screen variety. The bottom line is to not let price be the single and only deciding factor to determine what is best for you.

Understanding Code Behind in .Net Framework

December 2nd, 2006

Understanding Code Behind in .Net Framework

The ASP.NET Code Behind feature in .Net Framework allows developers to separate the server-side code from the presentation layer. This concept makes the server-side code to store in one file and the presentation code, that is, HTML code in another file. When you compile the ASP.NET page both these files get compiled as a single entity. In the traditional ASP model, this could not be achieved which often leads to intermingling of the code and the design.

The biggest advantage, in ASP.NET, is that the presentation code will be in .aspx file and the server-side code will be in any .Net compatible language such as Visual Basic.Net, C#, or J#. You can also do away with the presentation layer because you can give this role to the web designers. This saves time and you can concentrate only on the coding part of the application. In addition, you can create a class for your code and inherit this class from the ASP.NET Page object. By this way the class can access the page intrinsics and also interact with the postback architecture. After this you can create the ASP.NET page and apply a page directive to inherit from this new class.

But before you create an ASP.NET Code Behind class, you have to reference it to a namespace. The namespace could be System.Web.UI or` System.Web.UI.WebControls. Next you have to inherit the class from the Page object. You must declare some public instances of server controls using the name for the variables that are similar to the web controls. This procedure will create a link between the ASP.NET Code Behind class and the server controls.

You can use the ASP.NET Code Behind feature in various web applications development tools such as Visual Studio.Net and ASP.NET Web Matrix. They provide very easy ways to use the ASP.NET Code Behind. After dragging and dropping the server control from the Toolbox to the web page you can just right click on it to view the ASP.NET Code Behind page.
