Ramdom Acess Memory (RAM)

computer uses RAM to temporarily store the data that will be processed by the central processing unit (CPU),where it can store data, so the size of the RAM, measured in kilobytes or megabytes, is an important indicator of the capacity of the computer.with the addition of more RAM, you will be able to keep more programs open at once, speed up program launches, and experience fewer system crashes.Fitting RAM in your PC is a simple upgrade to perform, requiring little technical expertise and only taking around ten minutes time to complete.

What's the most common type of RAM today:

SDRAM: Synchronous dynamic random access memory takes advantage of the burst mode concept to greatly improve performance. It does this by staying on the row containing the requested bit and moving rapidly through the columns, reading each bit as it goes. The idea is that most of the time the data needed by the CPU will be in sequence. SDRAM is about five percent faster than EDO RAM and is the most common form in desktops today. Maximum transfer rate to L2 cache is approximately 528 MBps.

DDR SDRAM:Double data rate (DDR) synchronous dynamic RAM is just like SDRAM except that is has higher bandwidth, meaning greater speed. Maximum transfer rate to L2 cache is approximately 1,064 MBps (for DDR SDRAM 133 MHZ).

The DDR2 memory.

What is DDR2?
Stands for "Double Data Rate 2." DDR2 RAM is an improved version of DDR memory that is faster and more efficient. Like standard DDR memory, DDR2 memory can send data on both the rising and falling edges of the processor's clock cycles. This nearly doubles the amount of work the RAM can do in a given amount of time. DDR and DDR2 are also both types of SDRAM, which allows them to run faster than conventional memory.

While DDR and DDR2 have many similarities, DDR2 RAM uses a different design than DDR memory. The improved design allows DDR2 RAM to run faster than standard DDR memory. The modified design also gives the RAM more bandwidth, which means more data can be passed through the RAM chip at one time. This increases the efficiency of the memory. Since DDR2 runs more efficiently than standard DDR memory, it actually uses less power than DDR memory, even though it runs faster. The only downside of DDR2 memory is that it is not compatible with standard DDR slots. So make sure your computer supports DDR2 RAM before upgrading your memory.



*update :The latest development now is DDR3.while the DDR2 is the trend today.

Brief:

If you plan to buy a computer component guides to learn on how to do build a powerful system.If you are not in hurry, i really don’t see any necessity in doing this. As far as you know the power of Internet ,and know how to use the Internet to learn and to browse the products that you wish to buy,do your research ,you can find a bunch of free, useful and interesting information regarding these aspects. However,there might too much information that confused you.

This blog will share with you some of my favorite computer parts and buying tips when it comes to buying computer hardware parts. However,even if it seems like nothing complicated for dummies.

We all have difference need on the system that we need,before give our hard earned money to any retailers out there. Knowing what you really need is necessary?

In most of the cases you are going to need to have a large storage,fast loading time computer system,even you not going to use it each and every day,large amount of storage and memory space is necessary for today demanded application software needs, but for those just in case situations when dealing with a bunch of unexpected tasks,you will be willing to prepare something fast and get the jobs done if you have an fast machine.Good news is the new hardware today can easily be used both home PC desktop and laptop.

If you are out going person , it is a good to have powerful high speed laptop with mobile wireless broadband connection.It will definitely prove to be very helpful for your Carree. If you are totally newbie ,there is so much to be learn. This informational blog will show you how to get the right computer hardware without wasting a lot of money and time on research.
