The Function of Computer

The term “computer” in its complete form does not adequately represent what the device is capable of doing. The following are some of the fundamental tasks that, in addition to calculations and computations, are carried out by a computer:

Input

 The input function permits a computer to accept data from the user via input devices such as a keyboard, mouse, etc.  

Data Processing

The data is then passed via the computer’s Central Processing Unit (CPU) for processing once it has been taken in by the input devices of the computer. This is the primary function of the computer system, and the CPU plays an important part. The data that is supplied into the computer has to be processed, modified, or organised in such a manner that it may ultimately present the result that is intended to the person using the computer. 

Control Unit (CU):

The control unit of a computer is in charge of performing the input/output memory function as well as any other activities that are necessary for data processing.

The Arithmetic Logical Unit (ALU):

This unit is responsible for carrying out the mathematical and logical calculations that are necessary for the central processing unit to carry out its data processing functions.

Memory Unit (MU):

The memory unit is responsible for storing, processing, and retrieving the information necessary to carry out the function. It also enables temporary data storage.

Output

Following the completion of data processing, the data or the intended result or information is shown to the user through output devices such as monitors, printers, and the like. The output function is the very last function of the computer system, and its primary purpose is to provide the user with the system’s ultimate outcome.

COMPUTER Full Form: Full Form of Computer is “Common Operating Machine Purposely Used for Technological and Educational Research”. When computers were initially created in the middle of the 20th century, the phrase was first used. Computers were initially utilized for research in science and the military, but with time, their use spread. These devices were given the title of “computer” to denote their function, which was to calculate and handle massive volumes of data.
