RAM–Random Access Memory (also see DRAM, SDRAM). It is a data storage device that does not affect the speed of access as different locations are accessed. This is an anti-thesis to the magnetic tape or magnetic disk where data access is much quicker sequentially because physical movement is required in non-sequential location of the storage medium rather than just electronic switching. RAM’s are usually built from semi-conductor integrated circuits, which can be dynamic (DRAM) or static (SRAM).
