CPU (Central Processing Unit)

The CPU, or Central Processing Unit, is the primary part of a computer that performs calculations and processes instructions to run programs. Think of it as the brain of the computer, interpreting commands and managing tasks efficiently. It receives data, processes it according to the instructions, and sends the results to other parts of the system. The CPU's speed, measured in GHz, affects how quickly your computer can perform tasks. It works closely with memory and storage to ensure smooth operation, making it essential for everything from browsing the internet to complex computing.
