What is Bios? How its working

The BIOS (Basic Input/Output System) on a desktop motherboard is a firmware that is embedded on a chip on the motherboard. It provides the fundamental instructions that allow the computer to boot up and initialize the hardware components such as the CPU, memory, and storage devices.

When you power on your desktop computer, the BIOS first performs a Power-On Self Test (POST) to check if all the hardware components are functioning properly. If the POST completes successfully, the BIOS then loads the operating system from the storage device into the computer’s memory.

The BIOS also provides a user interface for configuring the hardware settings of the computer, such as setting the system time and date, adjusting the boot order, and enabling or disabling specific hardware components.

In summary, the BIOS is a critical component of a desktop motherboard that enables the computer to function properly and provides a way for users to configure hardware settings.
