Firmware

Firmware is software stored in read-only memory (ROM) or programmable ROM (PROM). Easier to change than hardware, but harder than software stored on disk. Firmware is often responsible for the behavior of a system when it is first switched on. A typical example would be a "monitor" program in a microcomputer which loads the full operating system from disk or from a network and then passes control to it.. Accessed 2020-09-10.
