Computer is an electronic automatic data processing machine. There are five basic operations that a computer can perform. They are input operations, output operations, storage operations, controlling operations and processing operations.
Overview Of Basic Computer Operations
People use computers for their incomparable speed, accuracy and performance. Computers help mankind to save their energy, money and time. Ever since the invention of the computer, the size of the computer is getting smaller and its performance power is increasing day by day. Basic operations on a computer include input, output, storage, process, and control.
All computer systems perform the following and five basic data operations;
01. Inputting
It is the process of inserting data and instructions into a computer system. Information and programs are entered into the computer through input devices such as keyboards, discs or other computers through network connections or modems connected to the Internet. The input device also receives information from the disk.
02. Storing
It is the process of storing data and instructions so that they are available when needed for initial or additional tasks.
03. Processing
It is the process of performing arithmetic or logical operations on data such as compare, equal, reduce, increase, etc., to convert them into useful information. The CPU or Central Processing Unit is sometimes called the Control Unit and directs the operation of input and output devices.
Memory or RAM temporarily stores information (files and programs) while you are using or working on them. The BIOS or Basic Input/Output System controls the communication between different devices. Where the computer does the data crunching. For example, reading electrical signals from a microphone, pictures from a camera, then mixing them together to make a video.
04. Outputting
It is the process of producing useful information or results for the person using the computer. such as a published report or visual display. The output device displays information on a screen (monitor) or printer and sends the information to other computers.
They also display messages about whether errors can occur and bring up a message or dialog box asking to input more information. The output device also saves information to disk for future use.
05. Controlling
Finally, this debate is the 5th basic operation. Control is a "combination of operations", for example copying a file;
Input - read file from flash drive.
Processing - Make a copy on the local hard disk, memory allocation, error checking, etc…
Data Storage - Save the copied data from flash disk to local hard disk.
Output - Use the monitor to show file copy progress and results.
It is the process of directing the manner and order in which all of the above tasks can be performed. Yes, control is basically "coordination". But some do not consider it a basic operation, because it is more of a "combination" and not a "basic one".
Advantages Of Basic Operations On Computers
Operations performed using a computer can ensure accurate results.
Operations performed using a computer save time and cost for the user.
The biggest advantage of computer operation is the speed with which the computer processes information.
Operations performed using a computer give output in the format that the user requires ( for example: audio, video, printed document, etc ).
Disadvantages Of basic Operations On Computers
The computer works on the given instructions. If an incorrect input is given, or if it is programmed incorrectly, the user will not get the desired result.
Computers that perform complex operations require very high configuration systems that are too expensive to afford.
