What is the difference between firmware and software?
Ordinary software is installed on top of an operating system and can be added or removed freely. Firmware is written into the device itself and makes the hardware work at all, so it is replaced only through a deliberate update process. A phone app is software; the code that makes your washing machine's controls respond is firmware.
Is BIOS firmware?
Yes. The BIOS, and its modern successor UEFI, is the firmware of a computer's motherboard. Firmware is the broader category, covering the code inside drives, keyboards, cameras and countless other devices.
Why do devices get firmware updates?
Manufacturers issue them to fix faults, close security holes, support new accessories or occasionally add features. Because firmware runs the device itself, an interrupted update can leave hardware unusable, which is why the process warns against cutting the power.
