Firmware
Firmware is a computer software that contains the instructions for how the device interacts with the rest of the computer hardware. It can store fundamental device functionalities, like BIOS of PC and may offer hardware abstraction services to higher-level software, like operating systems. Firmware is considered "semi-permanent" since it does not change unless it is updated by a firmware updater.
