ROM full form in computer

ROM stands for Read-Only Memory. In computers, ROM is a type of non-volatile memory that stores permanent data and instructions required to start the computer. The data in ROM cannot be modified or deleted, making it a reliable source of information for the computer’s basic input/output system (BIOS). The BIOS performs a power-on self-test (POST) to check the system components and loads the operating system into the RAM for execution.
