what is the brain of the computer

The brain of the computer is the central processing unit (CPU) . The CPU is responsible for processing input, storing data, and outputting results. It is an integrated circuit that contains millions or billions of tiny electrical parts, arranging them into circuits and fitting them all into a compact box. The CPU is constantly following instructions and managing the timing of each operation, similar to the human brain. It is where all the work is done, processing information using RAM for the incoming data and the final output. In essence, the CPU controls how data flows throughout the entire computer system under the influence of instructions, which are called "programs".
