Answer
What Is Firmware
What Is Firmware  
Computers, routers, switches, printers, cameras, and a lot of electronic devices have a chip that stores the firmware.
Firmware explains to the device what it is, how it works, and how it connects.
Firmware is most often NEVER updated.
Rarely, for some computers, there will be a recommended firmware update, usually to fix an error or bug in the software (firmware).
Some firmware upgrades are easy, some difficult, most are dangerous if done wrong. A bungled firmware update can make the device unusable.
