Read only memory is a permanent storage medium which stores start up programs of the operating system programs. These programs are loaded to computer when the computer is switched on. ROM stores essentially the BIOS programs which are recorded by the manufacture of the computer system. ROM is non – volatile memory. The programs stored in ROM are etched in to memory circuit and are available in a chip. This permanent software in ROM is called as firmware. Note that the firmware programs in ROM are not loaded in to memory form disk. System programs and language translators are stored in ROM chips.
