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
MicroDIMM (172 and 214 pin) for notebooks
Other memory:
Proprietary, branded, 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)
168 pin DIMM (Dual Inline Memory Module) RAM Memory, used in personal computers. PC66, PC100, and PC133 MHz 64Bit types.
200-pin SO-DIMM memory (small outline dual in-line memory module) for notebooks and some small footprint PCs.
DDR2 SDRAM standard computer memory (Double Data Rate Two Synchronous Dynamic Random Access Memory) for computers.
Proprietary memory is formatted to a specific brand or company's specifications compared to standard memory, which is interchangeable among different brands. Proprietary memory includes all company-specific memory for computers, laptops, printers and other devices.
