Firmware

Firmware is the name given to any software that is encoded into a read-only memory (ROM) chip and can be run without extra instructions from the operating system.

Most computers use firmware in some limited sense.

The best example of firmware is a computer’s CMOS setup program, which is used to set the options for the computer’s BIOS (time/date and boot options, for example).

Also, some expansion cards, such as Small Computer System Interface (SCSI) cards, use their own firmware utilities for setting up peripherals.
