Firmware is a type of software that is embedded directly in a piece of hardware to make the hardware work as intended. Firmware is programmed by the manufacturer and is installed on a digital device right in the factory.
Firmwer microcode comes in various complexities and can be found in simple digital devices, like keyboards and more complex devices like connected vehicles.
When a device is powered on, Flash File sends instructions to the device’s processor to execute. If the device is as simple as a keyboard, the flash file continues to execute as there is no software to replace it. However, in more complex devices, such as PCs, laptops and tablets, multiple file sets interact to achieve a common goal; load the operating system.
According to the U.S. Department of Homeland Security (DHS) and Department of Commerce, flash file is now a priority target for hackers and represents a significant threat vector for computer systems and IT infrastructure. In response, many manufacturers are updating their file more often to improve device security and performance.
How to Update Firmware
Shohag Technology YouTube Channel. The Internet of Things (IoT) raised the need for an efficient way to update edge device firmware. Updates can be distributed over a network or over-the-air. Over-the-air (OTA) technology allows firmware updates to be rolled out to a connected vehicle wirelessly and eliminate the need for an auto technician to physically install an update in the vehicle.
To update firmwar, device owners and IT managers should:
1. Check with the device’s manufacturer to see if a firmware update is available.
2. Set aside enough time to ensure the firmware update won’t be interrupted.
3. Backup the device in question — this will also back up the device’s current firmware.
4. Download and install the firmware update
