RAM

(Random Access Memory) pronounced ramm, computer hardware that stores
and accesses data as needed from any location within the memory on a short
term basis. RAM holds needed information from the application currently running,
allowing for quick access as it is called up. The data stored in RAM is
cleared when the computer is shut down. There are two types of RAM. Dynamic
RAM and Static RAM. (DRAM and SRAM) To facilitate its own functioning,
DRAM requires an electrical charge, which is refreshed thousands of
times each second while in use. While SRAM is faster because it doesn’t need
to be refreshed, it is considerably more expensive than DRAM. Because of its
higher speed, SRAM is often used for caching. RAM refers to a computer’s
main memory as opposed to read-only memory (ROM), which contains necessary
pre-recorded data used for booting the computer and other routine functions.
