Advantages and Disadvantages of Computer in Day to Day Life / Types Of Computer and Future of Computer in English

 What is computer, its utility and features

A computer is a machine that performs tasks according to certain instructions. It is an electronic device that is designed to work with information. This word computer is derived from the Latin word “computare”. It means to calculate or to calculate.

It mainly has three functions. Taking the first data which we also call Input. The second task is to process that data and then the task is to show that processed data which is also called Output.

Charles Babbage is said to be the father of the modern computer. Because he was the first to design the mechanical computer, which is also known as the Analytical Engine. In this, data was inserted with the help of punch card.

So we can call a computer such an advanced electronic device that takes raw data from the user as input. Then processes that data through a program (set of instruction) and publishes the final result as Output. It processes both numerical and non numerical (arithmetic and logical) calculations.

Advantages and Disadvantahes and Future of Computers

What is the full form of computer?

Technically there is no full form of computer. Still there is an imaginary full form of computer,

history of computer

It cannot be properly proved that since when the development of computer started. But officially the development of computer has been classified according to the generation. These are mainly divided into 5 parts.

When it comes to the generation of the computer, it means that the generations of the computer in Hindi. As the computer developed, they were divided into different generations so that it is easy to understand them properly.

1. First Generation of Computer – 1940-1956 “Vacuum Tubes”

The first generation computers used vacuum tubes for circuitry and magnetic drums for memory. They used to be quite big in size. A lot of power was used to run them.

Being very large, it also had a lot of heat problem, due to which it used to malfunction many times. Machine language was used in these. For example, UNIVAC and ENIAC computers.

2. Second Generation of Computer – 1956-1963 “Transistors”

In second generation computers, transistors replaced vacuum tubes. Transistors took up very little space, were smaller, were faster, were cheaper and were more energy efficient. They used to generate less heat than the first generation computers but still there was still a problem of heat in it.

In this, high level programming languages ​​like COBOL and FORTRAN were used.

3. Third Generation of Computers – 1964-1971 “Integrated Circuits”

Integrated Circuit was used for the first time in third generation computers. In which the transistors were small and inserted inside the silicon chip, which is called Semi Conductor. It benefited from this that the processing capacity of the computer increased to a great extent.

Monitors, keyboards and operating systems were used for the first time to make computers of this generation more user friendly. It was launched in the market for the first time.

4. Fourth Generation of Computers – 1971-1985 “Microprocessors”

The specialty of the fourth generation is that Microprocessor was used in it. Due to which thousands of Integrated Circuits were embedded in a single silicon chip. This made it very easy to reduce the size of the machine.

The use of microprocessor increased the efficiency of the computer even more. This very work was able to do very big calculations in Samaya.

5. Fifth Generation of Computer – 1985-present “Artificial Intelligence”

Fifth generation is of today’s era where Artificial Intelligence has established its dominance. Now many advanced techniques like new technology like Speech recognition, Parallel Processing, Quantum Calculation are coming into use.

This is a generation where due to the artificial intelligence of the computer, the ability to take decisions on its own has come. Gradually, all its work will be automated.

Who invented computer?

Who is called the father of modern computer? In this way, many people have contributed in this computing field. But out of all this, Charles Babage contributes more. Because he was the first to come out with the Analytical Engine in 1837.

The concept of ALU, Basic Flow Control and Integrated Memory was implemented in this engine. Based on this model, today’s computer was designed. That is why his contribution is the highest. That is why he is also known as the father of computer.

definition of computer in English

There are many components of any modern digital computer but some of them are very important like Input Device, Output Device, CPU (Central Processing Unit), Mass Storage Device and Memory.

How does computer work?

Input (Data): Input is the step in which raw information is inserted into the computer using an input device. It can be a letter, picture or even a video.

Process: The data inputted during the process is processed according to the instruction. This is completely internal process.

Output: The data which is already p during the output

The process has been done, it is shown as a result. And if we want, we can save this result and keep it in memory for future use.

The main circuit board of any computer is called the motherboard. It looks like a thin plate but it is holding many things. Such as CPU, memory, connectors for hard drives and optical drives, expansion cards to control video and audio, as well as connection to all the ports of the computer. If seen, the motherboard is directly or in direct connected with all the parts of the computer.


Do you know what is Central Processing Unit ie CPU? This is also called. It is found in the motherboard inside the computer case. It is also called the brain of the computer. It is keeping an eye on all the activities within a computer. The higher the speed of a processor, the sooner it will be able to do processing.


We also know RAM as Random Acess Memory. This is the short term memory of the system. Whenever the computer does some calculations, it temporarily saves that result in RAM. If the computer is turned off, this data is also lost. If we are writing a document, then to avoid it being destroyed, we should save our data in between. By saving, if the data is saved in the hard drive, then it can stay for a long time.

RAM is measured in megabytes (MB) or gigabytes (GB). The more RAM we have, the better it is for us.

Hard Drive

Hard Drive is the component where software, documents and other files are saved. In this, the data is stored for a long time.

Power Supply Unit

The job of the power supply unit is to take power from the main power supply and supply it to other components as per the requirement.

Expansion Card

All computers have Expansion Slots so that we can add an Expansion Card in the future. These are also called PCI (Peripheral Components Interconnect) cards. But today’s motherboard has many slots already built in. Names of some expansion cards that we can use to update old computers.

Video Card

sound card

Network Card

Bluetooth Card (Adapter)

computer hardware and software

We can call computer hardware any such physical device that we use in our computer, while computer software means the collection of codes that we install in the hard drive of our machine to run the hardware.

For example, the computer monitor that we use to navigate, the mouse that we use to navigate, these are all computer hardware. Wherein the Internet Browser from which we visit the website, and the Operating System in which that Internet Browser runs. We call such things software.

We can say that a computer is a combination of software and hardware, both have similar roles, both can do any work together.

With this, people can save anything whenever they want and can search for anything easily. We can say that computer is a very versatile machine because it is very flexible in doing its jobs.

But despite this, we can also say that the computer is a very versatile machine because it is very flexible in doing its work, while these machines also have some important advantages and disadvantages.

Let us know about them.

Advantages of Computer In English

1. Multitasking

Multitasking is a great advantage of computer. In this, a person can easily calculate multiple tasks, multiple operations, numerical problems in a few seconds. Computer can easily calculate in trillion of instructions per second.

2. Speed

Now it is no longer just a calculating device. Now it has become a very important part of our life.

Its great advantage is its high speed, which helps it to complete any task, that too in a very short time. In this, almost all the operations can be done immediately, otherwise it would take a lot of time to do them.

3. Cost / Stores do a large amount of data

It is a low cost solution. Because in this a person can save a large amount of data in a low budget. Using a centralized database, a very high quantity of information can be stored, so that the cost can be earned to a great extent.

4. Accuracy

These computers are very accurate about their calculations, the chances of making a mistake in them are negligible.

5. Data Security

Protecting digital data is called data security. Computer protects our digital data from unauthorized users such as cyberattack or access attack.

disadvantages of computer in English

Now let us know about some disadvantages of computer.

1. Virus and Hacking Attacks

Virus is a destructive program and hacking is called that unauthorized access in which the owner does not know about you.

These Viruses can be easily removed through email attachment.

They can be spread by, sometimes even over USB, or they can be accessed to your computer from any infected websites.

Whereas once it reaches your computer then it ruins your computer.

2. Online Cyber ​​Crimes

Computers and networks are used to do these online cyber-crimes. Whereas Cyberstalking and Identity theft also come under these online cyber-crimes.

3. Reduction in employment opportunity

Since the computer is capable of doing many tasks simultaneously, there is a huge loss of employment opportunity.

Therefore, from the banking sector to any governmental sectors, you see that all computers are given more importance in the place of people. So unemployment is only increasing.

Talking about the second disadvantage, then it does not have IQ, it totally depends on the users, it has no feeling, it cannot take any decision by itself.

future of computer In English

By the way, day by day a lot of technological changes are coming in the computer. Day by day it is becoming more affordable and with more performance and more capacity. As the need of the people increases, there will be more changes in it. Earlier it was of the size of a house, now it is getting absorbed in our hands.

There will come a time when it will be controlled by our mind. Nowadays scientists are doing more research on Optical Computer, DNA Computer, Neural Computer and Quantum Computer. Along with this, a lot of attention is also being paid to Artificial Intelligence so that it can do its work smoothly on its own.
