Question
__21. ROM in a computera) contains instructions that can be changed or erased.b) contains instructions that cannot be changed.c) solves mathematical equations.d) stores numeric data.
Solution
b) contains instructions that cannot be changed.
ROM stands for Read-Only Memory. It is a type of storage medium that permanently stores data on personal computers and other electronic devices. As the name indicates, data stored in ROM may only be read. It is either non-volatile or extremely slow to write to. It contains the programming that allows your computer to be booted up or regenerated each time you turn it on. Unlike a computer's random access memory (RAM), the data in ROM is not lost when the computer power is turned off. The ROM is sustained by a small long-life battery.
