RAM Memory
Computer Memory

Memory chips Random Access Memory, also referred to as RAM, Memory, computer memory, PC memory, and RAM Memory is the computer's temporary data bank. It is used for storing programs, such as the system's operating system (O/S) and the other data that is currently running on the computer. This data is loaded as it is needed. When the computer is turned off, RAM Memory is completely cleared.

The computer's permanent memory is in the hard disk drive. When you turn on your computer again, your O/S and other files that are needed are once again loaded into RAM.

RAM Memory allows rapid and random access to the data it is storing, thus providing the data that is needed when it is needed. This rapid accessibility is what makes computers run smoothly.

In general, there are two types of RAM Memory, DRAM and SRAM. DRAM is slower but much cheaper, it is thus much more common. Most computers have a form of DRAM. SRAM is much faster and much more expensive, so it is seen only in high-end computers. Both types of RAM are microchips (pictured at the top), so they are small in size. They are not inter-compatible.

If you have a slow computer, adding more of the exact type of DRAM or SRAM memory chips you already have in your computer will enable your computer to work considerably faster.
