Is ALU an independent unit?

ALU is an independent unit. Although it falls under the CPU (Central Processing Unit), ALU (Arithmetic Logic Unit) works independently of the other components of the CPU and its main task is to perform the arithmetical and logical calculations which are passed by the Control Unit (CU) to it.

Is ALU is an independent unit if not which unit does ALU work in coordination with?

ALU is stands for arithmetic and logical unit which performs all arithmetic operations like addition, subtraction, division and multiplication and logical operations of the computer system. It works the coordination of control unit and memory unit. It is the building block of CPU.

What is ALU control unit?

An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. The control unit tells the ALU what operation to perform on that data, and the ALU stores the result in an output register. The control unit moves the data between these registers, the ALU, and memory.

Is an independent unit?

Yes, ALU is an independent unit because it performs the functions independently. Explanation: It is a circuit that is used to perform mathematical functions such as arithmetic and logical functions. ALU is a component of the ‘central processing unit’ of a computer.

How is CPU different from ALU?

The difference between ALU and CPU is that ALU is an electronic circuit, which is a subsystem of CPU that performs arithmetic and logical operations while a CPU is an electronic circuit that handles instructions to operate the computer.

What is CPU 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.

Can you distinguish CPU and ALU Class 11?

The key difference between ALU and CPU is that the ALU is an electronic circuit which is a subsystem of CPU that performs arithmetic and logical operations while CPU is an electronic circuit that handles instructions to operate the computer. They are the ALU and the Control Unit.

What is ALU What are the functions performed by the ALU?

function in digital computer The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND. The memory stores the program’s instructions and data. The control unit fetches data and instructions from memory and… (3) control unit, and (4) arithmetic-logic unit.

What does ALU mean?

function in digital computer …of a control unit, an arithmetic logic unit (ALU), a memory unit, and input/output (I/O) controllers. The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND.

Can ALU distinguish CPU?

The main difference between CPU and ALU is that the CPU is an electronic circuit that handles instructions to operate the computer while the ALU is a subsystem of the CPU that performs arithmetic and logical operations. ALU and CU are major subcomponents of the CPU.

What is meant by ALU?

: a circuit in a computer’s central processing unit that performs basic mathematical calculations … the core of a central processing chip is the arithmetic logic unit or units. These units do basic operations like addition, multiplication and division. — New York Times, 23 July 1998 —abbreviation ALU.
