RAM stands for Random Access Memory. RAM provides space for your computer to read and write data to be accessed by the CPU (central processing unit). When people refer to a computer's memory, they usually mean its RAM. New computers typically come with at least 256 megabytes (MB) of RAM installed, and can be upgraded to 512MB or even a gigabyte or more. If you include more RAM to your computer, you reduce the number of times your CPU must read data from your hard disk. This usually allows your computer to work considerably faster, as RAM is many times faster than a hard disk.

RAM is volatile, so data stored in RAM stays there only as long as your computer is running. As soon as you turn the computer off, the data stored in RAM disappears. When you turn your computer on again, your computer's boot firmware (called BIOS on a PC) uses instructions stored semi-permanently in ROM chips to read your operating system and related files from the disk and load them back into RAM.

It is always better to do some research, before you actually buy any RAM. Here are some tips for when you consider buying a RAM

==> First of all you must know what type of RAM (SD, DDR, and DDR2) your motherboard supports. Now it is time for you to decide how fast RAM you want and how fast your motherboard can support. You might have seen RAM sticks as DDR 333 MHz, DDR 400 MHz, DDR2 533 MHz etc. This clock (MHz) is your bandwidth factor. The more it is, the better it will be. To know, either look at the manual provided with your motherboard or do a little search on Google with your motherboard model number. Now you are ready with what type and MHz of RAM you want.

==> Latency is the time delay only after which the data can be accessed in the RAM. So the less latency, the better it is. No need to go into the details of latency because low latency RAMS are 30% to 100% more costly than high latency RAMS.

==> Dual Channel is like you are running two identical sticks in combined mode, doubling the data transfer rate. This feature needs to be supported by the motherboard. Just insert two identical sticks in same colored module and it’s done.

==> Buying RAM running greater than FSB is pointless. FSB is how fast data can be transferred between processor and RAM. There is no point of buying a 667 MHz stick if your processor has a FSB of 533 MHz.
