Meaning – The term RAM, or random access memory, refers to a form of computer memory that can be read and changed in any order, typically used to store working data and machine code.
A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media, where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement.
Example of usage – “Software can partition a portion of a computer’s RAM, allowing it to act as a much faster hard drive that is called a RAM disk. A RAM disk loses the stored data when the computer is shut down unless memory is arranged to have a standby battery source.”
