The Central Processing Unit (CPU), also called a processor, is located inside the computer case on the motherboard. It is often called the brain of the computer, or the computer’s engine. Its job is to carry out commands. Whenever you press a key, click the mouse, or start an application, you’re sending instructions to the CPU.

The processor determines how fast a computer can execute instructions. A processor’s speed is measured in megahertz (MHZ), or millions of instructions per second, and gigahertz (GHZ), or billions of instructions per second. So, the higher the hertz, the faster the computer can process instructions. The power of the processor is measured in bits. The more bits a processor can handle, the more data it can handle, and therefore, the more powerful the processor.
