The diagram illustrates the main parts of a CPU, which are essential for processing all instructions from computer programs. The Control Unit manages the CPU's operations and directs the flow of data. The Arithmetic & Logic Unit performs mathematical operations and logical decisions. The Memory Unit, often linked with RAM, is responsible for storing data temporarily while the CPU processes it. Finally, the Secondary Unit, although not traditionally part of the CPU in modern architectures, may refer to secondary storage or additional processing modules.
