I want to tell you the basic computer, maybe you already know something, but my purpose is to give you information about the whole computer and not half of it. I know you know the basic computer information. But do you know how it works, who created it before, through what cords it passed. How many changes have been made to see the changes in computer capabilities over the years.

The result of many scientists' years of hard work behind the computers we are using today. At the same time, with half the imperfect knowledge, you have good knowledge. Today I want to give you complete information about this device as well as what people call this article computer, what are its main parts, full form of computer and how it works. So let's start with what the delay is and know what a computer is.

What is Computer

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

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

Full Form Of Computer

Technically there is no full form of computer. Yet there is an imaginary full form of computer,
C- Commonly
O - Operated
M - Machine
P- Particularly
U - Used for
T - Technical and
E - Educational
R - Research

History Of Computer

It cannot be accurately verified that since the development of the computer was started. But officially computer development has been classified according to generation. They are mainly divided into 5 parts.

When it comes to computer generation, it means that computer generations in hindi. As the computer develops, they are divided into different generations so that they can be understood in an accurate way.

First generation of computers - 1940-1956 "Vacuum Tubes"

First generation computers used Vaccum tubes for circuitry and Magnetic Drum for memory. They used to be quite large in size. It used a lot of power to run them.

Due to its large size, it also had a lot of heat problems which caused malfunction at times. They used to use Machine Language. For example, UNIVAC and ENIAC computers.

Second generation of computers - 1956-1963 "Transistors"

In second generation computers, transistors replaced vaccum tubes. Transistor used to take very little space, was small, faster, cheaper and more energy efficient. They used to generate less heat than the first generation computer, but still there was heat problem.

High level programming languages like COBOL and FORTRAN were used in these.

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

Integrated Circuit was first used in third generation computers. In which the transistors were inserted into small silicon chip called semiconductor. The advantage of this is that the computer's ability to process has been greatly increased.

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

The fourth generation of computers - 1971-1985 "Microprocessors"

It is a feature of the forth generation that it uses Microprocessor. Thousands of Integrated Circuits were embedded in a single silicone chip. This made it very easy to reduce the size of the machine.

With the use of microprocessor, the efficiency of the computer has increased. This very thing was able to do large calculations in the Time.

Fifth Generation of Computer - 1985-present "Artificial Intelligence"

Fifth generation is today's doorstep where Artificial Intelligence has dominated.

Now, newer technologies like Speech recognition, Parallel Processing, Quantum calculation and many advanced technologies have come into use.

This is a generation where, due to artificial intelligence of computer, self-decision making has been lacking. Gradually all its work will be Automated.

Now day's We Can see 8th generation computer in market


Who invented the computer?

What is the father of a modern computer? So many people have made their contribution to this computing field. But more than all of this is contributed by Charles Babage. Because they were the first Analytical Engine to come out 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 their contribution is the highest. Only then they are also known as the father of the computer.

Definition of Computer

There are many components of any modern digital computer but some of them are very important.

Such as Input device, Output Device, CPU (Central Processing Unit), Mass Storage Device at Memory.

Accepts Data Input
Processes Data              Processing
Produces Output          Output
Stores Result                 Storage

How Computer Works?

Input (Data):

Input is the step in which raw information is used in the computer using the Input Device. It can be a letter, a picture or a video.

Process:

Data that is input during processing is processed according to instruction. This is a completely Internal process.

Output:

During the output, the data that has already been processed is shown as 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 holds a lot of things like CPU, memory, connectors for hard drive and optical drive, expansion card to control video and audio, as well as all of the computer, Ports connection. When viewed, the motherboard is connected directly or directly to all parts of the computer.

CPU/Processor:

Do you know what a Central Processing Unit is? Also called. These are found in the motherboard inside the computer case. It is also called the brain of the computer. It monitors all the activities inside a computer. The higher the speed of a processor, the faster it will be able to process.

RAM:

We also know RAM by the name of Random Acess Memory. This is the System's Short Term Memeory. Whenever a computer does some calculations, it temporarily saves that result in RAM. If the computer closes, this data is also lost. If we are writing a document then we should save our data in the middle to avoid it being deleted. If you save the data to a hard drive by saving, it can last longer.

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

Hard Drive:

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

Power Supply Unit:

It is the job of the power supply unit to take power from the main power supply and supply it to other components as needed.

Expansion Card:

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

1. Video Card
2. Sound Card
3. Network Card
4. Bluetooth Card( adapter)



Computer hardware and software :
Computer hardware can be called a physical device that we use in our computer, whereas computer software means a collection of codes that we install on our machine's hard drive to run the hardware.
For example, computer monitors that we use to fall, the mouse that we use to navigate are all computer hardware. There is the Internet Browser with which we visit the website, and the operating system in which it runs Internet Browser. We call these things software.

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

Whenever we ever use the word computer, the picture of personal computer comes to our mind. Let me tell you that there are many types of Computers. Comes in various Shapes and Size. We use them as needed to extract ATM money, Scanner to scan a barcode, Calculator to do a large calculation. These are all different types of computers.
1. Desktop:

Many people use Desktop computers for their homes, schools and for their personal work. They are designed in such a way that we can put them on our desk. There are many Parts like Monitor, Keyboard, Mouse, Computer Case.

2. Laptop:

As you may know about Laptop which are battery powered, they are very portable so they can be taken anywhere and anytime.

3. Tablet:

Now let's talk about Tablet which we also call Handheld Computer because it can be easily caught in the hands.
It does not have a Keyboard and Mouse, just a touch sensitive screen which is used for typing and navigation. Example- iPAD.

4. Server:

A server is the type of computer we use to exchange information. For example, whenever we search something on the Internet, all those things would be stored in the server itself.

Other Types Of Computers

Smartphone:

When a normal cell phone has internet enabled, we can do many things using it then such cell phone is called smartphone.

Wearable:

Wearable technology is a common term for a group of devices - including fitness trackers and smartwatches - that are designed to be worn all day long. These devices are often called wearables.

Game Control:

This game console is also a special kind of computer that you use to play video games on your TV.

TV:

A TV is also a type of computer that now includes a lot of applications or applications that convert it to a Smart TV. Now you can stream videos from the Internet directly to your TV.
