What is Bios
BIOS (Basic Input/Output System) is a firmware program that is stored on a small memory chip on the motherboard of a computer. It is responsible for booting the computer and testing the hardware components to make sure they are functioning properly.
When you turn on your computer, the BIOS performs a series of checks and tests to make sure that all the necessary hardware is present and functioning properly. It then starts the boot process by looking for the operating system on the hard drive or other bootable devices, such as a USB drive or CD/DVD.
The BIOS provides a set of instructions that tell the computer how to boot and what devices to check for an operating system. It also contains settings that you can configure, such as the boot order (the order in which the computer checks for bootable devices) and system time and date.
You can usually enter the BIOS by pressing a specific key or key combination during the boot process. This key or key combination will vary depending on your specific computer model. Once you are in the BIOS, you can use the arrow keys on your keyboard to navigate through the different menus and make changes to the BIOS settings.
