The computer’s central processing unit (CPU) is electronic circuitry in a computer that processes instructions and tells each part of the system what to do. It’s arguably the most critical and defining component of a computer. Without it, your PC will not be able to do anything.

If your PC were a restaurant, the CPU would be its head chef. The quicker the chef works, the faster the food can be served to customers. Similarly, a CPU with higher processing power can perform more tasks faster.
