Question

A. Because it retains data even when the computer is turned off
B. Because it can be easily modified and updated
C. Because it is temporary and volatile
D. Because it stores data temporarily during processing

Answer 1

ROM is known as permanent memory because it retains its contents even when the computer's power is off, ensuring the computer can boot up and operate correctly.

Step-by-step explanation:

ROM, or Read-Only Memory, is called permanent memory because it retains data even when the computer is turned off. This is in contrast to RAM (Random Access Memory), which is volatile and loses its data when power is lost. The permanency of ROM stems from the fact that it is pre-programmed with data or instructions that are essential for the computer to boot up and function correctly. Thus, unlike RAM, the contents of ROM are not meant to be changed often. While there are types of ROM that can be updated or flashed, these updates are not done frequently and require specific processes. ROM is integral to the computer's ability to start and run the operating system, making it fundamental for the proper functioning of the device.
