Technology has its own terms which may require self-tutoring to understand. The tutor defines firmware.
instructions that reside in a device for the purpose of performing its pre-set functions. Typically, firmware is device-specific and meant to operate without the user’s awareness. It can be updated in order to resolve performance issues or increase the device’s capability.
Firmware is programming that runs hardware. Routers and mobile phones, for instance, have firmware. A PC does as well: its firmware enables it to cooperate with the monitor, keyboard, disk drives, etc.
