The actual mathematical operation for each instruction is performed by a combinational logic circuit within the CPU’s processor known as the arithmetic–logic unit or ALU. In general, a CPU executes an instruction by fetching it from memory, using its ALU to perform an operation, and then storing the result to memory.

How does a CPU work short answer?

The CPU sends signals to control the other parts of the computer, almost like how a brain controls a body. The CPU is an electronic machine that works on a list of computer things to do, called instructions. It reads the list of instructions and runs (executes) each one in order.

What does CPU mean in a game?

The central processing unit (CPU), also referred to as the “processor,” carries out and controls the computer program’s instructions by performing input/output (I/O) operations, basic arithmetic, and logic.
