What is BIOS?

Answer:

 BIOS stands for Basic Input-Output System and is pronounced as “Bye-Ose“. The BIOS is available on all the computers. It makes sure that all the components of the computer can function together. It has information about all the hardware components in the Computer. BIOS can also be called as a Special Software that interfaces the major hardware components of a computer with the Operating System. It is usually stored in a Flash Memory Chip on the Motherboard.

Some functions of BIOS: 

• Performs a POST (Power-On Self Test) for all the different Hardware Components in the System to make sure everything is working properly.
• Activating other BIOS Chips on different cards installed in the computer, for example, SCSI and Graphics Cards.
• Provides a set of low-level suiting that the Operating System uses to interface different Hardware devices.
•  BIOS manages things in your computer like the Keyboard, Monitor, Serial and Parallel Ports especially when the computer is Booting up.
• Manage the settings for Hard-disk drives, System Clock etc.
