Firmware is software installed on a small memory chip on a hardware device. Firmware allows hardware like cameras and smartphones to be updated.

Firmware is software embedded into hardware. Hardware like GPUs, hard drives, SSDs (solid state drives) and more can also come with firmware. Also commonly referred to as the BIOS, motherboard.

Firmware is software that's embedded in a piece of hardware. You can think of it simply as "software for hardware." However, software is different from firmware, so the two are not interchangeable terms.
