Changing the software in a non-volatile memory chip. Firmware updates are not frequent but sometimes necessary, and they can be performed by the user. In many cases, the firmware in a product was never intended to be changed, and the update process can be a bit tedious. If the firmware was designed for periodic updates, the installation of the revised software may be simple. See firmware, flash BIOS and FOTA.
No longer the domain of only desktop computers, firmware is being updated all over the place. As soon as this Blu-ray player was installed, it prompted the user for a firmware update, which took place over a Wi-Fi connection and TV set.
