At its core, a CPU is a complex electronic circuitry designed to interpret and execute instructions stored in computer memory. It comprises several key components, including the Arithmetic Logic Unit (ALU), Control Unit (CU), and Registers, working in harmony to perform calculations, manage operations, and store temporary data.

• Arithmetic Logic Unit (ALU): The ALU is the brainchild of computational operations, performing arithmetic (addition, subtraction, multiplication, division) and logical (AND, OR, NOT) functions on data.
• Control Unit (CU): The CU serves as the traffic cop, directing the flow of instructions and coordinating the activities of the ALU, memory, and input/output devices.
• Registers: High-speed storage locations within the CPU, they hold data temporarily, facilitating quick access during processing.
