Question

Which is true of ROM? ?

O Reading a ROM is called programming the ROM
O ROM is a volatile memory
O Writes to a ROM are faster and more frequent than reads
O ROM retains stored bits when power is removed

Answer 1

ROM is a non-volatile memory, meaning it retains stored data when power is removed. The other statements about ROM are incorrect as it is not intended for frequent writing operations, programming refers to its initial manufacturing process, and it is not volatile.

Step-by-step explanation:

The question asks which statement is true of Read-Only Memory (ROM). The correct answer is that ROM retains stored bits when power is removed. This is because ROM is a type of non-volatile memory, which means it does not require power to maintain the information stored in it. Unlike RAM, which is volatile and loses its data when power is lost, ROM preserves its data. The other statements are incorrect: Reading a ROM is not called programming the ROM (programming is the initial writing of data to ROM); ROM is not volatile; and writes to ROM are not only uncommon but are also slower compared to reads since ROM is typically programmed during the manufacturing process and not intended for regular writing operations.
