ROM(Read-only-memory): Read-only-memory is type of memory that has already been written during the computer system manufacturing and can only be read and not re-written, which is unlike RAM that can be read and re-written.Also another thing that's different between ROM and RAM is that unlike RAM ROM is non-volatile, what this mean that even after the power has been shut off to the computer system the data that is in the ROM does not go away. Most ROM will be in the form of a flash memory chip which is built into the mother board.

What does ROM store on the computer:
One program that will be stored in the ROM is the  Bios which stand for Basic input/output system. The role of the bios is to run a boot sequence when the computer is turned on to get it started so that the computer system can be used. Another role of the bios is to manage data flow between the computers operating system and attached devices such as input device, output devices and storage devices. Another use of the bios is to check on componets of the computer system without having to load the OS. For example you could check the fans RM+PM(rotation per minute), the CPU's speed, the cpu temperture, power usage and etc.
