Characteristics of Computer & Basic Function Of Computer

Today in this article you will learn about what is the characteristics of the computer, the overall development of computer technology had dramatically enlarged the basic features of computers before computers were used only for calculations or for specific tasks. Still, today machines have reached every part of human life.

Characteristics of Computer

No one can imagine life in their life without their use and computers have made a significant impact in our lives, machines are present in every field like schools, private institutions, hospitals, their presence is everywhere and so on. Has taken the human workload on its shoulders and has been providing us with excellent and amazing results.

What is Computer

A computer is an electronic device that processes the data input by the user and provides the information. As a result, i.e. a computer is an electronic machine that follows the instructions given by the user.

The Basic Characteristics of Computer are as following

Characteristics of Computer
  1. Speed
  2. Automation
  3. Accuracy
  4. Memory
  5. Versatility
  6. High Storage Capacity
  7. Diligence
  8. Reliability
  9. No Feeling & No IQ

What are the Characteristics of Computer


You can go anywhere on foot but still use a bicycle, scooter or car so that you can do any task faster. With the help of machine you can increase the speed of work. Similarly, Computer can do any job very fast. Computer can do millions of operations like multiplication, division, addition, subtraction in just a few seconds. If you have to find the value of 500 * 44, then you will take 1 or 2 minutes. It will take a second, but the Computer can do millions of such calculations in a few seconds.


We use many types of automatic machines in our daily life. The Computer also does all its work automatically. The Computer does its job automatically once the program is loaded.


Computer does all its work without any mistake. If you are asked to multiply ten different numbers, you will make mistakes many times. But in general, Computer can complete any process without any error. The biggest reason for Computer to make a mistake is to do wrong data input because Computer itself never makes any mistake.


This is one of the most important features of computers, these days they can store or save almost any amount of data due to high storage capabilities. Once you store any information or data in computer memory, that data will remain there until someone deletes or copies it.

You can get your data anywhere if you have stored your data correctly. We humans forget the little information given to us, but these machines keep our information safe forever, which is fantastic. These machines can store data as the user wishes.

Memory is measured in megabits (MB), gigabytes (GB) and terabytes (TB). Hard disks and pen drives are examples of mind.


The computer is increasingly gaining dominance all over the world due to its universality. The computer has started to be used for performing mathematical tasks as well as for business tasks. Computers are being used in every field Such as- Bank, Railway, Airport, Business, School etc.

High Storage Capacity

A computer system has a very high capacity to store data. A computer can save millions of words in a tiny space. It can store all types of data, pictures, files, programs, games and sound for many years. And later we can get any information in a few seconds and bring it to our use.


Today human beings get tired of doing a task continuously for a few hours. On the contrary, a computer can do a job consistently for many hours, days, months. Yet, its ability to perform a task does not decrease, and Nor does the accuracy of the result of the work decrease. Computer performs any given task without any discrimination, whether that task is exciting or not.


The memory of the Computer is more powerful, the whole process connected to the Computer is reliable, it does not get tired while working for years, and the store memory remains accurate even after years.

Power of Remembrance

A person does a lot of things in his life but remembers only the essential items, but the computer stores all the elements whether it is necessary or not inside the memory and later provides any information when needed.

No Feeling & No IQ

Computers cannot feel anything, and they do not have their intelligence. They do not think anything like humans, such as fatigue, boredom, laziness, jealousy or boredom. Since they do not have their intellect, they are dependent on human beings; they cannot make their decision based on computer logic.

Computer errors occur when someone gives an incorrect input, computer scientists are working on AI (Artificial Intelligence) which will make them so powerful and accurate that they will make their decision, and solve the problem with their arguments. This type of Computer has incredible features that will change the entire generations of computer systems.

Basic Function Of Computer

So let’s understand with an example. We have to type a word document or letter in computer, first, we will open MS-word and use mouse and keyboard to type a message in it, which was input. Now we will save this letter and do formatting for printing which is called Processing. Finally, we will print out the message, which is called Output. This is how we do all the work of computer. Think about Input-process-Output.

Computer Input & Output


This is the process of computer in which the user gives data or instruction to computer.


In this process, any Mathematical or Logical operations are performed inside the computer.


This is the final process of the computer where after processing the input data, the result is displayed in an output device. Like the article, you are reading right now is the Output of the link to this page. When this page was loading, it was Processing. When typed in Google search What is Computer in Hindi, this was input.

Computers have changed a lot in society. Computers have changed the way human beings live. Computers and the Internet have combined to make the work of people all over the world more accessible. Computers can do a lot of work without getting tired.

A few years ago, What seemed like an impossible task has now become much more comfortable. It is a small machine but very powerful. And for people, there is nothing less than magic. So let me tell you guys about the advantages and disadvantages of computer. First, we know about the benefits of computer.

Basic Components of Computer

The following are the main components of a computer. Click on the link to know more about them.

Input Devices

This is one of the essential parts of a computer. A user uses a device called an input device to provide a set of instructions and data to the computer. The CPU converts these instructions into binary data. Below are the names of some input devices

  • Mouse
  • Keyboard
  • Scanners
  • Touchpad
  • Mousepad

Output Devices

This is the second essential component. Output Device is the name of the device that is used to show the user the result that comes out after processing the input instruction. Below are the names of some output devices.

  • Monitor
  • Printer
  • Speaker

CPU (Central Processing Unit)

Just as we have brains, so do computers, which is called CPU. CPU performs all the processing operations. It has two main parts: one ALU and the other CU. ALU is an arithmetic and logic unit. CU stands for Control Unit. ALU – PERFORM ADDITION, SUBTRACTION, MULTIPLICATION AND DIVISION OPERATION.

Simultaneously performs some other operation. Which are called Comparison Operation? Such as> =, <=,>, <, =, not equal to. Nowadays, they are also called microprocessors or processors.

Storage Unit

Some digital memory is required to store data and instruction (TEXT, IMAGE, VIDEO, AUDIO). Storage devices are used for this digital memory. All storage devices are housed in a single unit called the Storage / Memory Unit. The storage unit is divided into two parts, one called Primary Memory and the other Secondary Memory. RAM is an example of primary memory. Hard disk, CD, DVD, pen drive are all examples of Secondary Memory. This was knowledge of some computer fundamentals.

Summary Words

  • A computer is an electronic device that processes information into user input and delivers data as a result.
  • A computer is an electronic machine that follows the instructions given by the user.
  • The biggest reason for a computer to make a mistake is to input the wrong data.
  • Computers can be used for performing mathematical tasks as well as for business tasks.
  • We can store data in a computer system for many years and then at any time in a few seconds.
