COMPUTER FUNDAMENTALS

Detailed explanation-1: -Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. ROM is useful for storing software that is rarely changed during the life of the system, also known as firmware.

Detailed explanation-2: -ROM can be read from but not written to, hence the term read only. This makes ROM ideal for storing instructions and data that are needed for the computer to run. These instructions and data are usually programmed by the computer’s manufacturer and cannot be overwritten.

Detailed explanation-3: -A programmable read-only memory (PROM) is a form of digital memory where the contents can be changed once after manufacture of the device. The data is then permanent and cannot be changed. It is one type of read-only memory (ROM).

Detailed explanation-4: -The programs which are as permanent as hardware and stored in ROM is known as Firmware. ROM stands for read-only memory. It’s used to store the start-up instructions for a computer, also known as the firmware.
