A Firmware Upgrade improves the functionality and features of your device. It can provide fixes to any performance issues that may occur.
So, what is a firmware?
Firmware or microcode is basically a set of instructions needed for certain devices to perform the tasks that they were made for. In simpler words, it is the programming that is responsible to run the machine. Unlike software, the firmware is not created to perform specific functions on the hardware, rather it is used to carry out the core functions of the hardware.
