What is firmware?

Advanced Search. Firmware is a software program or set of instructions programmed on a hardware device. It provides the necessary instructions for how the device communicates with the other computer hardware.

What is the difference between ROM&firmware?

Firmware is typically stored in the flash ROM of a hardware device. While ROM is “read-only memory,” flash ROM can be erased and rewritten because it is actually a type of flash memory. Firmware can be thought of as “semi-permanent” since it remains the same unless it is updated by a firmware updater.

How do I update the firmware on my Device?

You can usually find firmware updates by going to the “Support” or “Downloads” area of a manufacturer’s website. Keeping your firmware up-to-date is often not necessary, but it is still a good idea.
