Central Processing Unit
The Central Processing Unit (CPU) is the primary component of a computer system that performs most of the processing tasks. It is responsible for executing instructions of a computer program by performing arithmetic, logical, and input/output operations. The CPU consists of two main components: the control unit and the arithmetic logic unit. The control unit fetches instructions from memory and decodes them, while the arithmetic logic unit performs the actual calculations and logical operations. The CPU communicates with other components of the computer system through buses, which are pathways for data transfer. The performance of a CPU is measured by its clock speed, which is the number of instructions it can execute per second.
