Why do we use ROM?

Once data has been written onto a ROM chip, it cannot be removed and can only be read. Unlike main memory (RAM), ROM retains its contents even when the computer is turned off. ROM is referred to as being nonvolatile, whereas RAM is volatile.

What is the meaning of ROM?

The terms "RAM" and "ROM" refer to two types of computer data storage. RAM is an acronym for "random access memory," while ROM stands for "read-only memory." RAM and ROM are alike in certain respects as two forms of memory, so they are easily confused. In reality, they each play distinctive roles in the computer.
