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.

Answer:

HEY MATE HERE'S UR ANSWER

Explanation:

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. In addition to ALUs, modern CPUs contain a control unit (CU).

FURTHER WORKING APPLICATIONS

An ALU performs basic arithmetic and logic operations. Examples of arithmetic operations are addition, subtraction, multiplication, and division. Examples of logic operations are comparisons of values such as NOT, AND, and OR.

All information in a computer is stored and manipulated in the form of binary numbers, i.e. 0 and 1. Transistor switches are used to manipulate binary numbers since there are only two possible states of a switch: open or closed. An open transistor, through which there is no current, represents a 0. A closed transistor, through which there is a current, represents a 1.

An open transistor, through which there is no current, represents a 0. A closed transistor, through which there is a current, represents a 1.Operations can be accomplished by connecting multiple transistors. One transistor can be used to control a second one - in effect, turning the transistor switch on or off depending on the state of the second transistor. This is referred to as a gatebecause the arrangement can be used to allow or stop a current.

It uses a single input and produces a single output, which is always the opposite of the input. This figure shows the logic of the NOT gate.
