Random access memory?

RAM is used to temporarily store working data/code on an active computer system. Unlike on traditional storage devices, that is, a hard drive, data can be read/written on RAM at extremely fast speeds. Current technology allows the RAM chips to be created around an integrated circuit chip with metal oxide semiconductor cells. The data stored within the RAM chips is considered to be volatile. We lose volatile data when the computer system is no longer powered on. This is a significant reason the pull the plug tactic when responding to a scene involving activated computer systems is no longer recommended.

You may run into two different types of RAM: static RAM (SRAM) and dynamic RAM (DRAM). SRAM is considered faster and more efficient with respect to energy use, whereas DRAM is cheaper to produce than SRAM. You will typically find SRAM being used as cache memory for the CPU, and DRAM chips being used for memory chips for the computer system.
