Today’s why is called that is all about the most basic of computer parts, the BIOS.
BIOS, stands for Basic Input/Output system. This is what makes computers actually work, so highly important!
The BIOS, is a very small, simple BUT highly effective chip on the motherboard that tells the computer how to start, where it should look for the Operating System and even helps the Operating System to “talk” to the other bits and pieces. Without it we would not have working PC’s.
In recent times, it has been upgraded to UEFI, which stands for User Extensible Firmware Interface or i like to call it, BIOS 2 : The return, or BIOS with a mouse input 🙂
Either way, BIOS or UEFI, is a much needed and often overlooked component.
