When do we use rom?

Answer 1

ROM - Read Only Memory: This is like the Operating system, the things the computer needs and cannot be altered RAM - Random Access Memory: I think this is for temporary storage, which is delelted once the computer is turned off

Answer 2

ROM, read-only memory, is memory that does not lose its data when power is removed, and the data is usually only written to once, by the original manufacturer.

A program chip in an old-style arcade video game, a DVD movie, or an installable computer program on a CD are examples of uses of ROM.

True ROM is screened at the factory as is a Microprocessor. It cannot be changed without destroying the contents. There are many advantages to this as the contents can be counted on to remain the same throughout the life of the device it is installed in. This is also the major pitfall as it is not upgrade-able either.

ROM is a perfect medium to store boot-time instructions for a computer or portable device which are expected to be unchanging. Reading the boot track data for a device that includes magnetic media is one use for ROM. It can hold simple hardware diagnostics. It can also include audio-visual information such as standard sounds and icons or simple startup sounds and textual cues for system errors.

Almost all electronic media that is distributed on some hardware uses ROM. Video Games, DVDs, music. Almost anything that you would READ but not CHANGE.
