What are the Functions of a CPU?
A central processing unit, or CPU. The main part of a computer is system processing. Because it carries out commands, performs calculations, and regulates the data flow inside the computer That’s why CPU is also known as the brain of the computer. The CPU interprets and executes instructions from the computer’s memory, including arithmetic and logical operations, instructions for moving data around, and instructions for controlling flow. By modifying and processing data held in registers, caches, and main memory, it carries out these processes.
