What is BIOS and how does it work?
The Basic Input/Output System (BIOS) is a type of firmware that is embedded in a computer’s motherboard. It is responsible for controlling and coordinating the various hardware components of the system, such as the keyboard, mouse, and hard drive. The BIOS is executed when the computer is first powered on, and it performs a series of tests and initializations to ensure that the system is functioning properly. This process is known as the Power-On Self-Test (POST). During the POST, the BIOS checks the system’s memory, CPU, and other components to ensure that they are working correctly.
The BIOS also provides a set of settings and options that allow users to configure the system to their preferences. These settings can include things like the boot order, which determines the order in which the system searches for an operating system to load, as well as settings for the system’s time and date. The BIOS is typically stored in a non-volatile memory chip on the motherboard, which means that it retains its settings even when the power is turned off. This allows the system to remember its configuration and settings even after it has been shut down or restarted. Overall, the BIOS plays a critical role in the functioning of a computer system, and it is an essential component of the system’s architecture.
