On which computer hardware device is the BIOS chip located?

The BIOS chip is located on the motherboard because it is responsible for initializing and controlling essential hardware components during the computer's startup process. The motherboard acts as the central hub connecting all other hardware devices in the computer system, including the CPU, memory, storage, and expansion slots. Placing the BIOS chip directly on the motherboard ensures that it is easily accessible and can effectively communicate with these components to perform its crucial functions.
