Computer RAM (Random Access Memory) is the working memory of your computer. RAM stores programs and data currently being used by the CPU. This data consists of the program code and information that is quickly written to and read from the RAM in a way that requires no reading head or physical movement of the memory stick module.

Standard and generic memory can be used in different brands of machines.

Different types of memory modules are based on technology (such as DRAM), number of pins, and storage capacity expressed in bytes:

SIMM (30 and 72 pin) for older Intel desktops
DIMM (168, 184, 240 pin) for desktop computers
SODIMM (72, 144, 200, 204 pin) for notebooks
RIMM (184 pin) for Intel i820/i840 chipsets

Other memory:
Proprietary and 3rd party memory are designed and/or marketed for a specific systems or motherboards.
Printer and server memory may use any variety of DIMM, SODIMM, or unique proprietary type.
Cache memory is used for processor primary storage.
ROM (Random Access Memory) memory is used for read-only use that does not erase when there is no electrical power.
Flash Memory (for digital cameras, pdas, mp3 players)
