What is Computer - Basic information

Here we will talk about what is Computer. A computer is an electronic device if it is said in easy language. You probably already know this answer. So you must be thinking, why again this article today, about which we already know everything.

Just wait. Today I want to tell you what is the primary computer, these Hindi, you may know something in advance, but my objective is that you should be informed about the whole computer and not half of it.

I know you know basic computer information. But do you know how it works, who made it before, through which kisses it has passed? How many changes have been seen in the characteristics of computers in so many years?

The computer that we are using today is the result of years of hard work of many scientists behind it. In today's article, what do you call a computer, what is the central part of it, the full form of the computer and how it works, I want to give you complete information about this machine. Then what is the delay? Let's start with what is a computer.

What is Computer

"A computer is a machine that performs tasks according to certain instructions. There is an electronic device, which is designed to work with information. The word computer is derived from the Latin word "computare". This means calculating or calculating."

It has three main functions. The first is to take the data which we also call Input, the second task is to process that data, and the other task is to show the processed data, which is also called Output.

Who invented the computer? The father of modern computers is called Charles Babbage. Because he was the first to design a 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 an advanced electronic device that takes raw data from the user in the form of input. Processes that data through a program (set of Instruction) and finally the result as Output Publishes. It processes both numerical and non-numerical (arithmetic and logical) calculations.

What is the full form of computer?

Technically there is no full form of computer. Yet the laptop has a complete imaginary way,

C – Commonly, O – Operated, M – Machine, P – Particularly, U – Used for, T – Technical and E – Educational, R – Research

History of Computer

It cannot be properly verified that the development of computers has been started since. But officially computer development has been classified according to generation. They are divided into 5 parts from the central tower.

When it comes to the generation of computer, then it means that computer's generations in Hindi. As the computer grows, they are divided into different generations to make it easier to understand them properly.

First Generation of Computer - 1940-1956 "Vacuum Tubes"

The first generation of computers used Vaccum tubes for circuitry and Magnetic Drum for memory. They used to be very big in size. A lot of power was used to run them.

Being too big, it also had a lot of heat problem due to which it was even malfunctioned many times. Machine language was used in them. For example, UNIVAC and ENIAC computers.

Second Generation of Computers - 1956-1963 "Transistors"

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

High-level programming languages ​​such as COBOL and FORTRAN were used in them.

Third Generation of Computers - 1964-1971 "Integrated Circuits"

Integrated Circuit was first used in third-generation computers. In which the transistors were cut into small silicon chip called Semi-Conductor. Due to this, the ability to do computer processing increased to a great extent.

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

Fourth Generation of Computers - 1971-1985 "Microprocessors"

It is typical of the Forth generation that Microprocessor was used in it. Thousands of integrated circuits were embedded into 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 work was able to do a lot of calculations.

Fifth Generation of Computers - 1985-present "Artificial Intelligence."

Fifth-generation belongs to today's Dor, where Artificial Intelligence has established its dominance. Now, many new technologies like Speech recognition, Parallel Processing, Quantum Calculation have started coming into use.

This is a generation where due to the computer's artificial intelligence, the ability to make decisions on its own has come. Gradually all its works will be automated.

Who invented the computer

Father Of Computer Charles Babbage

Who is the father of the modern computer? Many such people have contributed to this Computing Field. But more of all this is provided by Charles Babbage. Because he was the first Analytical Engine came out in 1837.

The concept of ALU, Basic Flow Control and Integrated Memory was implemented in this engine. Today's computer was designed by basing itself on this model. This is why his contribution is the highest. Then he is also known as the father of the computer.

Definition of computer

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

accepts data	Input
processes data	Processing
produces output	Output
stores results	Storage

 How does the computer work

Input (Data): Input is the step in which Raw Information is inserted into the computer using Input Device. It can be a letter, picture or even a video.

Process: The data input during the process is processed according to the instruction. This is an entirely internal process.

Output: The data that has already been processed during the output is shown in the Result. And if we want, we can also save this result and keep it in memory for future use.

Nominee image of basic computer units

If you have ever looked inside a computer case, then you must have found that there are many small components inside, they look very complicated, but they are not really that complicated. Now, I will give you some information about these components.

Motherboard

The main circuit board of any computer is called the motherboard. It looks like a thin plate, but it holds many things like CPU, memory, connectors for hard drive and optical drive, to control expansion card video and audio, along with all of the computer Ports connection. If seen, the motherboard is directly or indirectly connected with all parts of the computer.

CPU / Processor

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

RAM

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 shuts down, then this data is also lost. If we are writing a document, then to protect it from being destroyed, we should save our data in between. If saved in Data Hard Drive by saving, then it can remain for a long time.

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

Hard drive

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

Power Supply Unit

The power supply unit's job 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. They are also called PCI (Peripheral Components Interconnect) cards. But nowadays the motherboard already has many built-in slots. Names of some Expansion Cards that we can use to update old computers.

Video card

Sound card

Network card

Bluetooth Card (Adapter)

NOTE - If you are ever opening the contents of COMPUTER then you should first remove PLUG from the main SOCKET.

Computer hardware and software

We can call computer hardware any physical device that we use in our computer, whereas computer software means the collection of codes that we install in our machine's Hard Drive to run the hardware.

For example, the computer monitor that we use to navigate, the mouse that we use to navigate, are all computer hardware. At the same time, the Internet Browser with which we visit the website, and the operating system in which that Internet Browser runs. We call such things as software.

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

Type of computer

Whenever we ever hear the use of the word computer, only the picture of the personal computer comes into our mind. Let me tell you that there are many types of computers. They come in various shapes and sizes. We use them as per the requirement, such as ATM to withdraw money, Scanner to scan a barcode, Calculator to do a significant calculation. These are all different types of computers.

1. Desktop

Many people use desktop computers for their homes, schools and their personal work. They are designed in such a way that we can keep them on our desk. They have many parts, such as Monitor, Keyboard, Mouse, Computer Case.

2. Laptop

You must have known about battery-powered laptops, they are very portable so that they can be taken anywhere and anytime.

3. Tablet

Now let's talk about the Tablet which we also call Handheld Computer as it can be easily caught in handguns.

It does not have a keyboard and mouse, just a touch-sensitive screen that is used for typing and navigation. Example- iPad.

4. Servers

A server is a computer of some sort that we use to exchange information. For example, whenever we search for something on the Internet, all those things are stored on the server.

Computer use

Where is the computer used? If seen, we have been using computers everywhere in our lives and will continue to do so. It has become a part of us. I have written some of its uses for your information below.

Use of computers in the field of education: They have the most significant hand in school, if a student needs information about something, then with the help of this information becomes available within a few minutes. Research has shown that with the help of computers, the learning performance of any student has increased significantly. Nowadays, sitting at home can be taught with the help of Online Classes.

Health and Medicine: It is a boon for Health and Medicine. With its help, patients are treated very quickly nowadays. Nowadays, everything has become digital, which makes it easy to know about the disease, and according to that, it is also possible to treat it. With this operation has also become easy.

Use of computers in the field of science: This is the result of science itself. This makes research very easy. Nowadays a new trend is going on, which is also called Collaboratory so that all the scientists of the world can work together, it does not matter that you have a presence in the country.

Business: It has a massive hand in-store to increase productivity and competitiveness. It is mainly used in Marketing, Retailing, Banking, Stock Trading. Due to all the things being digital here, its processing has become very fast. And nowadays more importance is being given to Cashless Transaction.

Recreation and Entertainment: It has become a new hangout for entertainment, you can talk about anything like Movies, Sports or restaurants wherever they are used everywhere.

Government: Nowadays, the government is also giving more focus on its use. If we talk about Traffic, Tourism, Information & Broadcasting, Education, Aviation, our work in all these places has become very easy.

Defence: Their use in the army has also increased to a great extent. With the help of which our military has become more powerful now. Because nowadays everything is controlled with the help of a computer.

There are many places where we use it according to our needs.

benefits of computer

By the way, it will not be wrong to say that machine has made the life of us very comfortable with the help of its incredible speed, accuracy and storage.

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

But in spite of 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 essential advantages and disadvantages.

Let's know about them.

Multitasking

Multitasking is a huge advantage of a computer.

In this, a person can easily calculate multiple tasks, multiple operations, numerical problems in just a few seconds.

A computer can easily calculate in trillion of instructions per second.

Speed

Now it is no longer just a calculating device.

Now it has become an essential part of our life.

Its great advantage is its high speed, which helps it to complete any task in a short time.

In this, all the operations can be done immediately. Otherwise, it will take a lot of time to do them.

Cost / Stores do large amounts of data

This is a low-cost solution. Because in this, a person can save a large number of data in a low budget. The use of a centralised database can store a very high quantity of information so that the cost can be earned to a great extent.

Accuracy

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

Data security

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

Computer damage

Now let us know about some disadvantages of Computer.

Virus and Hacking Attacks

A virus is a destructive program and hacking is called unauthorised access in which the Owner does not know about you.

These viruses can be easily spread through email attachment, sometimes even by USB, or they can be accessed from your infected websites by your computer.

At the same time, once it reaches your computer, then it ruins your computer.

Online Cyber ​​Crimes

Computer and network are used to do this online cyber-crime. At the same time, cyberstalking and identity theft are also covered under these online cyber-crimes.

The decrease in employment opportunity

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

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

Talking about the other disadvantage, it does not have an IQ, it depends on the users at all, it has no feeling, it cannot take any decision by itself.

Computer architecture

By the way, a lot of technological changes are coming on the computer day by day. Every day, it is becoming more affordable and more efficient and more efficient. As the need of the people increases, so will there be more changes. Previously it was of the shape of a house, now it is going in our hands.

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