READ ONLY MEMORY (rom)
- ROM is another type of memory permanently stored inside the computer.
- ROM is non-volatile. It holds the programs and data when the computer is powered off.
- Programs in ROM have been pre-recorded. It can only be stored by the manufacturer; once it is done, it cannot be changed.
- Many complex functions, such as start up operating instructions, translators for high-level languages and operating systems are placed in ROM memory.
- All the contents in ROM can be accessed and read but cannot be changed.
