BIOS: History, Applications, Art & Measurement

In computing, BIOS or the Basic Input/Output System is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup). On a computer using BIOS firmware, the firmware comes pre-installed on the computer's motherboard.
