State and explain the three components of CPU in a computer?

1. Control Unit (CU): The control unit is responsible for coordinating and controlling the operations of the CPU. It fetches instructions from memory, decodes them, and then executes them. The control unit also manages the flow of data within the CPU and between the CPU and other components of the computer system.

2. Arithmetic Logic Unit (ALU): The ALU is the component of the CPU that performs arithmetic and logical operations on data. It is responsible for carrying out mathematical calculations such as addition, subtraction, multiplication, and division, as well as logical operations such as AND, OR, and NOT. The ALU processes data according to the instructions provided by the control unit.

3. Registers: Registers are small, high-speed storage locations within the CPU that hold data temporarily during processing. They are used to store data, instructions, and addresses that are currently being processed by the CPU. Registers are faster than main memory, allowing the CPU to access and manipulate data quickly. Some common types of registers include the program counter (PC), memory address register (MAR), memory data register (MDR), and accumulator.
