Let’s know what is a computer ? A computer is a machine that processes instructions to calculate data and store and manage information. Computers are made up of hardware and software. Computer words, the Latin words ” Computare was taken “. Means account or account.

It mainly has three functions. Taking the first data we also call the 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 entered with the help of punched card.

So we can call the computer an advanced electronic device that takes the raw data from the user as input. Then it processes that data through a program (instruction set) and publishes the final result as output. It handles numerical and non-numerical (arithmetic and logical) arithmetic operations. I hope you liked what computer is.

What is the full form of a computer?

Technically there is no perfect form of computer. There is still a complete dummy form of the computer,

If you translate it to Hindi, something like this will happen, a common running machine used specifically for business, education and research .

How do computers work?

For some people, using a computer can be difficult to understand. This section will help you understand how to run your computer smoothly.

You must be wondering how you can use keyboard and mouse at the same time? Well, it’s not that complicated! Here are some instructions on how to do this:

1. Move your mouse pointer over the symbol or letter you want to click.
2. Press and hold the left mouse button.
3. Drag the pointer to where you want to click.
4. Release the left mouse button when you reach the desired destination.

computer history

This cannot be properly proven since when computer development began. But officially the evolution of the computer has been categorized by generation. These are mainly divided into 5 parts.

When it comes to computer generation, it means computer generations. With the development of the computer, they have been divided into different generations so that it is easier to understand them correctly.

1. The first generation of computers – 1940-1956 “vacuum tubes”

First-generation computers used circuit vacuum tubes and magnetic cylinders for memory. It was large in size. A lot of force was used to run it.

Being so big, she also had a lot of heat issues, which she crashed several times because of it. Machine language was used in this. For example, UNIVAC and  ENIAC computers .

2. The second generation of the computer – 1956-1963 “Transistors”

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

These include high-level programming languages ​​such as COBOL and FORTRAN. has been used .

3. Third generation of computers – 1964-1971 “Integrated Circuits”

Integrated circuits were first used in third-generation computers. Where the transistors were small and inserted inside a silicon chip, which is called a semiconductor. The benefit of this is that the processing power of the computer is greatly increased.

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

4. Fourth generation of computers – 1971-1985 “microprocessors”

The specialty of the fourth generation is that a microprocessor was used in it. Thanks to him, thousands of integrated circuits are combined into a single silicon chip. This made it very easy to reduce the size of the machine.

The use of microprocessors has increased the efficiency of the computer even more. This particular work was able to make very large calculations in Samaya.

5. The fifth generation of the computer – 1985 to date “artificial intelligence”

The fifth generation of today’s era where artificial intelligence has proven its dominance. Now many advanced technologies such as speech recognition, parallel processing and quantitative computation are used.

This is a generation where the ability to make decisions on their own came about because of the artificial intelligence of the computer. Gradually, all its work will be automated.

Who invented the computer?

Who is called the father of the modern computer? Many people have contributed to this computational field. But of all this, Charles Babbage contributes the most. Because he was the first to start operating the Analytical Engine in 1837. From .

The concept of ALU , basic flow control and integrated memory has been implemented in this engine . It is based on this model that today’s computer is built. That is why his contribution is the highest. This is why he is also known as the father of the computer.

computer identification

There are many components of a modern digital computer but some of them are very important such as the input device, the output device, the central processing unit (CPU), the mass storage device, and the memory.

How does the computer work?

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

Operation: The  data entered during the operation is processed according to the instructions. This is an entirely internal process.

Output: The data already processed during the output is displayed  as a result. And if we want, we can save this result and keep it in memory for future use.

Motherboard

The main circuit board of any computer is called the motherboard. It looks like a thin plate, but it contains many things. Such as the CPU, memory, hard drive connectors, optical drives, and expansion cards to control video and audio, as well as connectivity to all computer ports. If you see it, the motherboard is directly or directly connected to all parts of the computer.

CPU/Processor

Do you know what a central processing unit is, ie a central processing unit? This is also called. It is located on the motherboard inside the computer case. It is also called the brain of a computer. It monitors all the activities inside the computer. The higher the processor speed, the faster the processor.

RAM

We also know random access memory (RAM) as random access memory. This is the system’s short-term memory. When the computer does some arithmetic, it temporarily saves this result in RAM. If the computer is turned off, this data will also be lost. If we are writing a document, then to avoid damaging it, we must save our data between them. By saving, if the data is saved to the hard drive, it can remain for a long time.

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

hard disk

The hard disk is the component in which programs, documents, and other files are saved. In this, the data is stored for a long time.

power supply unit

The task of the power supply unit is to take power from the main power supply and supply it to other components according to the requirements.

expansion card

All computers have expansion slots so we can add an expansion card in the future. These are also called PCI (Peripheral Component Interconnect) cards. But today’s motherboard has several 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 computers any physical device that we use in our computer, while computer software means the set of codes that we install in our machine’s hard disk to operate the devices.

For example, the computer screen we use for navigation, the mouse we use for navigation, these are all computers. Where the Internet browser from which we visit the site and the operating system in which the Internet browser is running. We call these things software.

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

Types of Computer – Types of Computer in Hindi

Whenever we hear about the use of the word computer, only the image of a personal computer will come to mind. Let me tell you that there are many types of computers. It comes in different shapes and sizes. We use it as needed, like an ATM to withdraw money, a scanner to scan a bar code, and a calculator to do any major arithmetic. These are all different types of computers.

1. Desktop

Many people use desktop computers in their homes, schools, and personal work. It has been designed in such a way that we can keep it on our desk. They have many parts such as the monitor, keyboard, mouse, and computer case.

2. Laptop

Business: It  has a significant hand in business to increase productivity and competitiveness. They are mainly used in marketing, retail, banking and stock trading. Since it’s all digital here, it’s pretty quick to process it. Nowadays, more importance is given to non-cash transactions.

Recreation and Leisure:  This has become a new haven for entertainment, you talk about anything like movies, sports or restaurants, it is used everywhere.

Government:  Nowadays, the government is also giving more emphasis on its use. If we talk about traffic, tourism, information, radio, education and aviation, our work has become very easy because they are used in all places.

Defense:  Its use in the military has greatly increased. With the help of which our army is now more powerful. Because nowadays everything is controlled with the help of computer.

There are as many places we use as we need.

computer benefits

Well it would not be wrong at all to say that the computer has made the life of our human beings very easy with the help of which incredible speed, accuracy and storage .

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

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’s know about them.

1. Multitasking

Multitasking is a great feature of a computer. In this, anyone can easily calculate multiple tasks, multiple operations, numerical problems, and that too in a few seconds. A computer can easily calculate a trillion instructions per second.

2. Speed

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

Its big advantage is its high speed, which helps it to complete any task, and that too in a very short time. In this, almost all operations can be performed immediately, otherwise it will take a lot of time to perform them.

3. Cost / Stores do a large amount of data

It is a low cost solution. Because in this person he can save a large amount of data with a low budget. With a central database , a very large amount of information can be stored, so that the cost can be greatly earned.

4. Precision

These computers are very accurate in their calculations, and the odds of making a mistake in them are very slim.

5. Data security

Protecting digital data is called data security. The computer protects our digital data from unauthorized users such as a cyber attack or access attack.

Computer defects

Now let’s get to know some of the computer flaws .

1. Viruses – Hacking Attacks

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

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

Whereas, once it reaches your computer, it destroys your computer.

2. Cybercrime on the Internet

Computers and networks are used to carry out these cyber crimes over the Internet . Cyber ​​stalking and identity theft also fall under these online cybercrimes.

3. Reducing employment opportunities

Since the computer is able to perform many tasks simultaneously, there is a huge loss of business opportunities.

So, from the banking sector to any government sector, you see that all computers are given more importance where people are. That is why unemployment is only increasing.

When talking about the second drawback , it does not contain IQ , it depends entirely on the users , and does not have a sense , and can not take any decision alone .

The future of computers

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

There will come a time when our minds will rule. At present, scientists are doing more research on the optical computer, the DNA computer, the neural computer, and the quantum computer. Besides, a lot of attention is also paid to AI so that it can perform its work smoothly on its own.
