What refers to the memory that is not retained after a computer is powered off?

The term that refers to memory that is not retained after a computer is powered off is volatile memory. This type of memory requires a constant power supply to maintain the stored information. When the power is turned off, all data within volatile memory is lost.

Common examples of volatile memory include Random Access Memory (RAM), which is used by computers to store data temporarily while programs are running. This is in contrast to non-volatile memory, which retains data even when the power is shut off. Understanding this distinction is crucial when discussing computer memory types, as it affects how data is managed and stored in computing systems.
