Random access memory(usually known by its acronym, RAM) is a type of data
storage used in computers.70-528 The word "random" refers to the fact that any piece of
data can be returned in a constant time, regardless of its physical location and
whether or not it is related to the previous piece of data. This contrasts with storage
mechanisms such as tapes, magnetic discs and optical discs, which rely on the
physical movement of the recording medium or a reading head.156-215 In these devices, the
movement takes longer than the data transfer, and the retrieval time varies
depending on the physical location of the next item.
