Random-access memory (RAM; / r æ m /) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code.
Computer memory stores information, such as data and programs, for immediate use in the computer. [2] The term memory is often synonymous with the terms RAM, main memory, or primary storage. Archaic synonyms for main memory include core (for magnetic core memory) and store. [3]
Associated with speed, the more RAM there is in the system, the faster the computer can run, because it allows the RAM to run more information through to the computer's (CPU). Not only does adding more RAM to a computer help it run faster, it helps boots up a computer immensely faster compared to booting up a system with less RAM.
Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory ; data is lost when power is removed.
A RAM drive (also called a RAM disk) is a block of random-access memory (primary storage or volatile memory) that a computer's software is treating as if the memory were a disk drive (secondary storage).
