The system BIOS is the backbone of any PC both laptops and desktops and is by far the most important part of any device. It manages and controls all the hardware in a device and is heavily utilised by the operating system you have installed. Unsurprisingly, the BIOS is also one of the most neglected aspects of any PC. This is primarily because of its (usually) complex update process causing people to be hesitant about updating their BIOS.

As the keystone of any system, hackers and other nefarious agents are always looking for BIOS exploits and weaknesses to gain access to your systems. Because of this, it is important to make sure that you have the latest BIOS version installed on your computer.
