Detailed explanation-1: -ROM, which stands for read only memory, is a memory device or storage medium that stores information permanently. It is also the primary memory unit of a computer along with the random access memory (RAM). It is called read only memory as we can only read the programs and data stored on it but cannot write on it.

Detailed explanation-2: -Read-only memory, or ROM, is a type of computer storage containing non-volatile, permanent data that, normally, can only be read, not written to. ROM contains the programming that allows a computer to start up or regenerate each time it is turned on.

Detailed explanation-3: -The Digital Computer Read-only memory is permanent and is indelibly etched into the ROM chip during manufacture. ROM contains information (usually programs) that can be repeatedly read by the computer but cannot be modified.

Detailed explanation-4: -RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer.
