Firmware: Data stored in a computer or other hardware device ROM or elsewhere in the circuitry that provides instruction on how that device should operate. Unlike normal software, firmware cannot be changed or deleted by an end-user without the aid of special programs. It remains on the device regardless of whether the device is on or off.
Firmware Update: A software program that can be used to flash update the firmware in those devices. Firmware updates are made available through the hardware manufacturer. In some cases computer enthusiast’s websites offer firmware updates to give a device even more capabilities than the manufacturer intended, although these updates are not supported by the manufacturer.
