The BIOS chip stands for Basic Input/Output System. It is a firmware embedded on the computer's motherboard that is the first code executed when a PC is powered on. The BIOS chip's primary function is to initialize and test the system's hardware components (such as the processor, memory, and storage devices) through a process called the power-on self-test (POST). It also manages the data flow between the computer's operating system and attached hardware devices, effectively acting as a bridge between hardware and software during the booting process
. In summary, BIOS is essential for starting the computer, configuring hardware settings, and loading the operating system
