  • The smallest and fastest memory of a computer is Register Memory located in Computer's Central Processing Unit(CPU).
  • It generally stores the most used instructions, data etc. which to be used by CPU.
  • The control Unit is part of CPU. It advises the input and output devices, computer memory on how to respond to the instructions sent to the processor.
  • Input device unit is equipment use to provide input to the computer. i.e. keyboard
  • An output device unit helps in transferring information into human -readable form. For e.g. monitor

Control Unit Function in CPU:

Control Unit in CPU performs the following function:

- Decode Program Instruction: One of the main functions of the Control Unit is to decode the program instructions. It interprets and executes the instructions provided by the program.

- Perform Logical Operations: The Control Unit is responsible for performing logical operations such as AND, OR, NOT, etc. It controls the flow of data within the CPU and ensures that the instructions are executed in the correct sequence.

- Store Program: The Control Unit also stores the program instructions temporarily in the memory for execution. It fetches the instructions from memory, decodes them, and sends the necessary signals to other components of the CPU to execute the instructions.

Therefore, the correct answer is option 'A' - Decode Program Instruction. The Control Unit plays a crucial role in managing and coordinating the various components of the CPU to ensure smooth execution of programs.

Direction:In many of the process control applications, the purpose of control system is to keep the output (controlled variabl e) almost constant in spite of changes in load. Mostly in continuous processes the set point remains constant for longer time. Such an operation is called Regulator Operation. The set point generated, and the actual values from sensors are given to a controller. The controller compares both the signals, generates error signal which is utilized to generate a final signal as controller output. The controller output is finally utilized to physically change the values of manipulated variable to achieve stability. The above action is achieved with the help of final control elements. They are operatable either with electrical, pneumatic or with hydraulic signals. The system that serves good for servo operation will generally not be the best for regulator operation. Large capacity or inertia helps to minimize error here, whereas it makes the system sluggish in case of servo operation.Q.Which out of these is not the operational signal for control system ?
