What is CPU? Do you know CPU stands for Central Processing Unit?
Central Processing Unit (CPU) resides in almost all devices you own, whether it’s a smartwatch, a computer, or a thermostat. They are responsible for processing and executing instructions to other parts of the devices, acting as the brains of the devices. It’s one of the most important pieces of hardware in any device – if not the most important.
