How is ROM made?

The simplest type of ROM is that which uses tiny “fuses” which can be selectively blown or left alone to represent the two binary states. Obviously, once one of the little fuses is blown, it cannot be made whole again, so the writing of such ROM circuits is one-time only.

What is ROM explain?

ROM is an acronym for Read-Only Memory. It refers to computer memory chips containing permanent or semi-permanent data.

Why is ROM so important?

ROM provides the necessary instructions for communication between various hardware components. As mentioned before, it is essential for the storage and operation of the BIOS, but it can also be used for basic data management, to hold software for basic processes of utilities and to read and write to peripheral devices.
