What does the abbreviation ROM stand for?

The abbreviation ROM stands for Read Only Memory. This type of memory is used primarily in computers and other devices to store firmware or software that is not intended to be modified frequently, if at all.

Read Only Memory retains its contents even when the power is turned off, making it crucial for boot processes and the underlying instructions needed for devices to function. Unlike Random Access Memory (RAM), which is volatile and loses its data once power is removed, ROM is a non-volatile memory type. This characteristic ensures that essential programs needed for the computer's startup and operation are preserved, providing reliability and consistency.

While Read Once Memory, Random Access Memory, and Runtime Object Memory are terms used in computing, they do not correspond specifically to the functionalities and characteristics that define ROM.
