What does ROM stand for in computer terminology?

The term ROM in computer terminology stands for Read Only Memory. This type of memory is critical in computers and other devices, as it is used to store firmware or software that is not intended to be modified or erased during normal operation. ROM retains its contents even when the power is turned off, making it essential for booting up the system and providing the initial instructions needed for hardware initialization and system checks.

In contrast to other types of memory, such as RAM (Random Access Memory), which allows for both reading and writing of data, ROM is specifically designed to be read with limited or no ability to write new data. This characteristic ensures that the foundational code required for the hardware to function properly remains intact and unaltered, contributing to the stability and reliability of the system.
