Detailed explanation-1: -The control unit (CU) is a component of a computer’s central processing unit (CPU) that directs the operation of the processor. It tells the computer’s memory, arithmetic/logic unit and input and output devices how to respond to the instructions that have been sent to the processor.
Detailed explanation-2: -A control unit, or CU, is circuitry within a computer’s processor that directs operations. It instructs the memory, logic unit, and both output and input devices of the computer on how to respond to the program’s instructions. CPUs and GPUs are examples of devices that use control units.
Detailed explanation-3: -The control unit controls all CPU operations, including ALU operations, the movement of data within the CPU, and the exchange of data and control signals across external interfaces (system bus). Registers are high-speed internal memory-storage units within the CPU.
Detailed explanation-4: -ALU stands for Arithmetic and Logical Unit which performs Arithmetic functions like Addition, subtraction, division, etc. CU stands for control unit which performs the task of controlling functions of the computer. It monitors and gives proper instructions to all parts of the computer.
