firmware update - Computer Definition
Changing the software in a flash memory chip. With personal computers, firmware updates are infrequent but sometimes necessary to recondition older machines. The user can perform such updates, but it can be a tedious job. On the other hand, consumer products may be designed for periodic firmware updates, and the installation of the revised software should be no more difficult than "click here to update." See firmware, flash BIOS and FOTA.
