What are the characteristics of a computer?

computer plays a very important role to make human lives easier. It is becoming a fundamental need in our day-to-day regular activities. In this century, our life will be incomplete without the use of this wonderful device. The computer is a wonderful electronic machine, so you have to know the what are the characteristics of a computer

Some characteristics of the computer are described below.

1. High Speed

A computer can work at a very high speed and is much faster than humans. The operations on the data inside the computer are performed through the electronic circuits. The electronic circuit is designed in such a way that the electrical signal travels at the speed of light.


A computer has the capability to do several complex calculations within a second. The time taken by the computer to perform an operation is known as processing speed. This processing speed of the computer is measured in MegaHertz (MHz) or GigaHertz (GHz) that is the speed of the CPU.

2. Accuracy

Accuracy means providing results without any error. A Computer is an accurate machine. It does not make any mistakes. If the data and instructions given to the computer are correct, it always gives the correct result or output. A computer can process a large amount of data and generate error-free or almost 100% error-free results.


A computer can perform millions of operations in one second without any error. Sometimes a computer may produce an undesirable result due to wrong input. In computer terminology, that is known as garbage-in garbage-out(GIGO).

3. Versatility

It is the most important feature of a computer. The computer is a versatile and flexible machine because it can perform different kinds of tasks one by one simultaneously. It can perform different kinds of tasks such as calculation, drawing pictures, playing games, playing music, watching videos, writing letters, sending an e-mail, etc.


The working capacity of the computer depends on the software. We can use the same computer in different fields of work such as education, health, business, communication, aviation, scientific research, desktop publishing.

4. Storage Capacity

A computer can store a huge amount of data permanently. We can store any type of data on a computer and use this data at any time. Image, audio, and video files, different types of documents can be stored easily. In the computer, the stored data and programs are available at any time for processing.


The internal storage devices of computers are RAM and ROM and the external storage devices of computers are hard disk, pen-drive, CD and DVD memory card, etc. The storage capacity of the computer is increasing day by day rapidly. The following are the measurement units used to count the stored data in the computer.

5. Diligence

A computer is a diligent machine. Unlike human beings, a computer never feels tired and bored to do a task repeatedly for a long time. It can work for a long time without taking a rest. It can continuously work for a long time without creating any errors.  So the computer can perform the same task with the same speed and accuracy even for hours and days if it is provided a suitable environment and correct program.

6. Automatic

A Computer does not interfere with the user during the processing of data. Computers can be programmed to perform a series of complex tasks automatically. It automatically executes the program instructions one by one and automatically controls different devices attached to it.


To make the computer work automatic, a set of pre-defined instructions is fed into the computer. So, computers have been used for quality control in the industries which perform the task without getting any instructions from the operation.

7. Communication

Computers are mostly used in the field of communication to exchange messages or data through the internet all over the world. With the help of a computer, we can quickly receive or send any information throughout the world. There are many services available on the computer through which communications are possible such as e-mail, chatting, video conferencing, etc.

8. No intelligent

Although computers are faster, more powerful, and accurate than a human, it does not have common sense and can’t think and decide to do any task. It cannot learn from past experience and cannot change execution steps itself.

9. Electronic

A computer is an electronic machine developed to perform calculations and control operations that can be expressed either in logical or numerical terms. Most of the computer’s parts are electronic devices that are made of semiconductor chips.

At the end 

I have mentioned above the characteristics of a computer. If you find other characteristics or features, please mention the comment box. If you like this post please don’t forget to share it with social media
