Random Access Memory

computer memory where data is temporarily stored for quick retrieval (once the computer is turned off all data in RAM is lost)

Random access memory (usually known by its acronym, RAM) is a type of computer data storage. It takes the form of integrated circuits that allow the stored data to be accessed in any order — that is, at  random and without the physical movement of the storage medium or a physical reading head. RAM is a volatile memory as the information or instructions stored in it will be lost if the power is switched off.

Noun
1. the most common computer memory which can be used by programs to perform necessary tasks while the computer is on; an integrated circuit memory chip allows information to be stored or accessed in any order and all storage locations are equally accessible
(synonym) random-access memory, random memory, RAM, read/write memory
(hypernym) volatile storage
(part-meronym) buffer, buffer storage, buffer store

Random Access Memory, memory used for reading and writing, memory which enables immediate access to all data (Computers)

A read/write, nonsequential-access memory used for the storage of instructions and data. Note 1: RAM access time is essentially the same for all storage locations. Note 2: RAM is characterized by a shorter access time than disk or tape storage. Note 3: RAM is usually volatile.
