Firmware
Firmware is data stored on a computer or other electronic hardware including instructions to help those devices operate correctly. For instance, on a simple device (like a keyboard), firmware handles all actions that involve data manipulation, device control, and system monitoring. On more advanced devices (like smartphones), firmware helps load the operating system, which interacts with the apps you use daily.
As it is stored in ROM (read-only memory), firmware remains on a device, whether turned on or off, one of its essential features. All firmware is written using machine language and, unlike normal software, cannot be changed or deleted by an end-user without using special programs.
What is a firmware update?
A firmware update is similar to any other; it adds functionality to a device and patches potential security vulnerabilities. For example, a user could download a firmware update for a network router that enhances its security or improves its performance. Sometimes, computer enthusiast websites create firmware updates to give a device even more capabilities than the manufacturer intended. However, it's important to note that third-party updates are often not supported by the manufacturer.
How do I perform a firmware update?
To update firmware, check with your device's hardware manufacturer. If one is available, back up the device (if possible), then download and install the update.
