What is ROM

ROM

ROM stands for Read Only Memory. It is called so, as the user can only read from it and cannot write into it. It is a non-volatile memory as it stores information permanently and cannot be changed. The primary use of ROM is during the booting, which is the initial program to start up the computer, when power is switched on.

Example: An audio-video disk resembles ROM, as the songs once stored on it cannot be changed.
