What is a BIOS ?

What is a BIOS?

The acronym BIOS stands for Basic Input/Output System. When the computer is first started, the BIOS activates all of the hardware required by the computer to boot including:

  • Chipsets
  • Processors and Caches
  • System Memory
  • Internal Drives
  • Graphics and Audio Controllers
  • Internal Expansion Cards

After the BIOS completes this process, it transfers control of the computer to the operating system.
