Central Processing Unit (CPU)

The Central Processing Unit (CPU) is the main component of a computer responsible for executing instructions and processing data. It acts like the computer’s brain, interpreting commands from software and coordinating the activities of other hardware. The CPU performs basic operations such as calculations, data transfer, and decision-making. It consists of parts like the Control Unit, which directs operations, and the Arithmetic Logic Unit (ALU), which handles calculations. The CPU's speed and power determine how quickly and efficiently a computer runs tasks, making it essential for overall system performance.
