What devices use firmware?
Typical examples of devices containing firmware are embedded systems, consumer appliances, computers, computer peripherals, and others. Almost all electronic devices beyond the simplest contain some firmware. Firmware is held in non-volatile memory devices such as ROM, EPROM, or flash memory.
What happens if you don’t update BIOS?
BIOS updates will not make your computer faster, they generally won’t add new features you need, and they may even cause additional problems. You should only update your BIOS if the new version contains an improvement you need.
