Answer:
The central processing unit (CPU) is often referred to as the "brain" or "heart" of a computer. The CPU is the component of a computer that carries out the instructions of a computer program by performing basic arithmetic, logical, and input/output operations. It is the most important component of a computer, as it is responsible for executing the majority of the instructions that make up a computer program.
The CPU is typically made up of two main components: the control unit and the arithmetic logic unit (ALU). The control unit fetches instructions from memory and decodes them, while the ALU performs the actual calculations and logical operations specified by the instructions.
In summary, the CPU is considered the "heart" of a computer because it is the component that carries out the instructions of a computer program and performs the majority of the operations that make a computer work.
