Detailed explanation-1: -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-2: -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.
Detailed explanation-3: -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-4: -ROM cannot be written at all. PROM can be written once. EPROM can be rewritten, but only after exposure to a UV lamp.
