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.
