What are the responsibilities of Cu and ALU?
ALU and CU are the heart of the CPU. ALU is the Arithmetic and Logic Unit which performs all the arithmetic and logical operations such as addition, subtraction, logical AND, OR etc. CU is the Control Unit. It decodes the instructions, and controls all the other internal components of the CPU to make it work.
How does the control unit work?
A control unit works by receiving input information to which it converts into control signals, which are then sent to the central processor. The computer’s processor then tells the attached hardware what operations to perform.
What is a control unit in a CPU?
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.
What is the responsibility of logical unit in CPU?
To control flow of information.
What is ALU control unit?
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. The control unit moves the data between these registers, the ALU, and memory.
What do you understand by control unit?
The control unit (CU) is a component of a computer’s central processing unit (CPU) that directs the operation of the processor. It directs the flow of data between the CPU and the other devices.
What functions are performed by the control unit can we call it the control Centre of computer?
Answer: The Control Unit (CU) controls and guides the interpretation, flow and manipulation of all data and information. The CU sends control signals until the required operations are done properly by ALU and memory.
How important is control unit in a computer system?
It is very Important to have Control unit in a Computer System. Without a control unit its like a Body without a Brain. Control Unit controls all the Parts of the Computer it Porcesses all the Instructions given by us and Gives us an Output. Control unit of a Computer is a CPU.
What is the responsibility of the logical unit in the CPU of a computer A to produce result B to compare numbers C to control flow of information D to do maths works?

| C. | to control flow of information |
| D. | to do math’s works |
| Answer» b. to compare numbers |
Which unit of the computer system is responsible for receiving data from the outside?
Input Unit It accepts data and instruction from the outside worlds. It converts these data and instruction into computer understandable from a binary form. It supplied the converted data and instruction to the computer system for further processing.
What is the responsibility of the logical unit in the CPU of a computer?
What is the task of the control unit?
The control unit generates control signals that ensure the required sequence of execution of operations, monitors the operation of the computer in various regimes, and provides for the interface of the human operator with the computer.
What are the uses of control unit?
It is responsible for controlling the transfer of data and instructions among other units of a computer.
What is the function of the control unit in the CPU?
The control unit is the main component of a central processing unit (CPU) in computers that can direct the operations during the execution of a program by the processor /computer. The main function of the control unit is to fetch and execute instructions from the memory of a computer .
What is the control unit responsible?
The control unit is also responsible for setting the latches in various data paths that ensure that the instructions are performed on the correct operand values stored in the registers. In a CISCprocessor, the control unit is a small processor in its own right that executes microcode programs stored in a region of rom that prescribe the correct sequence of latches and data transfers for each type of macroinstruction.
