Before updating bios
Before you begin, make sure that you have power backup while upgrading the BIOS.
Unlike Microsoft Windows, anti-virus or other software updates which are usually automatic, BIOS on a PC has to be updated manually.
BIOS is a firmware that is embedded on a small memory chip on the PC's system board or motherboard.
It acts as an interface between the PC's hardware and the operating system.
In fact, most of the recent Windows versions like the Windows 10 handle the update process in a much more elegant manner as opposed to lets says Windows XP systems.
BIOS is an acronym for Basic Input/Output System, also known as System Setup.
