What is the definition of Alu?

Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations. The ALU is one component of the CPU(central processing unit).

What is the role of the 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.
  • What is the main function of ALU?

    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. Modern CPUs contain very powerful and complex ALUs.
  • What are the main functions of the CPU?

    Video: Central Processing Unit (CPU): Parts, Definition & Function. The central processing unit (CPU) is the brain of your computer. It handles all the instructions you give your computer, and the faster it does this, the better.
  • What is the role of virtual memory?

    Virtual memory is a memory management capability of an OS that uses hardware and software to allow a computer to compensate for physical memory shortages by temporarily transferring data from random access memory (RAM) to disk storage.

Is the ALU A register?

Registers and the ALU. The arithmetic/logic unit (ALU) of a processor performs integer arithmetic and logical operations. For example, one of its operations is to add two 32-bit integers. The second operand (often in a register).
  • What is the full form of Alu in computer language?

    An arithmetic-logic unit (ALU) is the part of a computer processor (CPU) that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units, an arithmetic unit (AU) and a logic unit (LU).
  • What is the meaning of memory unit?

    Memory unit is the amount of data that can be stored in the storage unit. This storage capacity is expressed in terms of Bytes.
  • What is a primary and secondary memory?

    Secondary storage (also known as external memory or auxiliary storage), differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers the desired data using intermediate area in primary storage.

What are the main function of the 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 tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions.
  • What is the main purpose of the CPU?

    Central Processing Unit. The CPU (Central Processing Unit) is the part of a computer system that is commonly referred to as the "brains" of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program.
  • What do you mean by input?

    Input can take a variety of forms, from commands you enter from the keyboard to data from another computer or device. A device that feeds data into a computer, such as a keyboard or mouse, is called an input device. (v.)The act of entering data into a computer.
  • What is the function of the printer?

    A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.
