Random number generation — A random number generator (often abbreviated as RNG) is a computational or physical device designed to generate a sequence of numbers or symbols that lack any pattern, i.e. appear random. Computer based systems for random number generation are… … Wikipedia
Random access machine — In computer science, random access machine (RAM) is an abstract machine in the general class of register machines. The RAM is very similar to the counter machine but with the added capability of indirect addressing of its registers. Like the… … Wikipedia

Magnetoresistive Random Access Memory — (MRAM) is a non volatile computer memory (NVRAM) technology, which has been under development since the 1990s. Continued increases in density of existing memory technologies ndash; notably Flash RAM and DRAM ndash; kept MRAM in a niche role in… … Wikipedia
Power supply unit (computer) — Power supply unit with top cover removed A power supply unit (PSU) supplies direct current (DC) power to the other components in a computer. It converts general purpose alternating current (AC) electric power from the mains (110 V to… … Wikipedia
Dynamic random access memory — (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically … Wikipedia
