# Who performs arithmetic and logical operations?

## Who performs arithmetic and logical operations?

ALU
The ALU carries out basic arithmetic and logic operations, and the control section determines the sequence of operations, including branch instructions that transfer control from one part of a program to another.

## Where are arithmetic and logical operations performed?

What Is an 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 completes arithmetic and logical operations?

Principal components of a CPU include the arithmetic logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that fetches instructions from memory and “executes” them by directing the coordinated …

### What is difference between logical and arithmetic operations?

Arithmetic operators perform their actions on numbers. Assignment operators assign values to variables. Logical operators compare two values and, based on whether the comparison is true (or false), return either a “true” or “false.”

### What are the four basic logic operations?

Elementary algebra has four operations, addition, subtraction, multiplication, and division, but Boolean algebra has only three operations: AND — a binary operator; the result is 1 if and only if both operands are 1; otherwise the result is 0. We will use ‘⋅’ to designate the AND operation.

What is the main function of ALU?

☆ It represents the fundamental building block of the central processing unit (CPU) of a computer. ☆The purpose of the ALU is to perform mathematical operations such as addition, subtraction, multiplication and division. ☆Additionally, the ALU processes basic logical operations like AND/OR calculations.
