As the name suggests, read-only memory, or ROM, stores information that can only be read. It contains the basic instructions for what needs to happen when a computer is powered on. This is typically referred to as the firmware of a computer. The firmware represents the basic code to get the computer started. Once the computer is up and running, the CPU takes over. Firmware is also referred to as BIOS, or basic input/output system.
