Firmware is programming that’s written to a hardware device’s “non-volatile” memory. In electronic systems and computing, firmware is a computer program that provides the “Low Level Control” (LLC) for the device’s specific hardware. Without firmware, most of the electronic devices we use daily wouldn’t be able to work. Firmware can start on its own and do what it is programmed or designed to do while drivers must be run by the operating system. Better known as software for hardware, Firmware is a program that comes embedded in a piece of hardware such as a keyboard, hard drive, BIOS, or a video card. Firmware can be thought of as semi-permanent since it remains the same unless it is updated by a firmware updater.
Firmware such as the program of an embedded system may be the only program that will run on the system and provide all of its functions.
How to Update Firmware:
Firmware updates are available from hardware manufacturers.
A firmware update is a software program that can be used to update the firmware in these devices.
IOS devices like iPhones and IPads also occasionally get firmware updates. These devices let you download and install the firmware from the device itself so you don’t have to manually download and install it yourself.
They also provide the necessary software tools to write the new firmware onto those devices.
Some firmware updates are applied wirelessly and just seem like a regular software update.
