A computer is an electronic machine that receives and processes the data inputted by the user and then provides the information to us through the output device as a result. Apart from this, you can also store data for the future.

           BASIC INFORMATION OF COMPUTER

Computer is also known as computer in Hindi. This is a machine that accepts data through an input device, then processes it and then shows us the results through the output device.

You can also store data in it, so that it can be used in future. Computer is made up of the Latin word "Computare" which means to calculate.

We use it to do many things easily. It also solves complex math problems in less than a second.

It does not understand the instructions given by us in our language but only as 0 and 1 which we speak machine language. This device is not just a use, it is used almost everywhere.

You will often go to many such places everyday where there will be government or private offices. Until a few years ago, people and files were used for their work in these places, i.e. paperwork was done.

But this machine caught such detail that now in every office, office you will see only this machine.

Full Form of Computer in Hindi?

 – Commonly

O – Operated

M – Machine

P – Particularly

U – Used for

T – Technical

E – Educational

R – Research

What is the definition of computer?

“A computer is an electronic device that processes the data inputted from the user programmatically and then shows the result as output. Which can also be used in future. "

The way it works is something like this.

From the process flow diagram shown above, you can easily understand what is the way of working of computer. It mainly works in 3 steps.

The user takes the data of the computer from the input device as input data, after which the data the user enters, it processes through its program.

After this, the data is shown to the user as output. It accepts and processes two types of data, one is Arithmetical and the other Logical.

It is such an electronic device that specializes in doing many things very quickly and easily.

But there are still many people in the world who do not know many important things about PCs.

What is the Hindi name of computer?

By the way, many people who do not really know what the computer's Hindi name is संगणक . Which means an instrument that performs calculations.

What is a computer screen called?

When we work in this device, we use the monitor for it, which is its output device. So you can yourself understand that the screen is called a monitor.

How does a computer work?

Input: - First of all, the user puts the data from the input device into it, it is called input.

This is set of data or information. Which are many types like letters, numbers, words, audio, video etc.

Processing: - This is an internal process. Processes the inputted data based on the instruction given in the program.

Output: - Processed data is viewed on the monitor as the result, it is called output. When the data is processed, we get it through the monitor screen, printer, audio device.

PARTS OF COMPUTERS

Input device

The device we use to enter data inside our PC is called an input device. We enter this data and instruction in different form using the input device.

An input device is a means of communicating directly between humans and the system.

Input devices are devices that directly access the CPU after inputting instructions and data. The instructions from these devices tell the brain of the system what to use?

There are different types of input devices that can input data and instruction. Here I am telling you about different input devices. Keyboard, Light pen, Digital Camera, Mouse, Scanner.

Motherboard

The motherboard is the main circuit board of the system. All parts are connected in it.

The CPU, Mouse, keyboard, printer, monitor and even devices are connected by cables directly to the motherboard. There is a hardware inside the motherboard system. We also call it the backbone of the system.

Apart from PCs and laptops, there are many devices in which the motherboard is used. Devices like mobile and tablet also have motherboard.

The shape and size of the motherboard of different systems varies according to the device. Some parts are connected directly to the motherboard itself.

CPU (Central Processing Unit)

If this is called the brain of the system, then it is not a wrong thing at all. The way a person thinks with his mind and takes a decision, in the same way the CPU works like a human mind in the system.

It is also known by many names, such as e-brain processor, central processor, and micro processor.

This system is in the motherboard inside the cabinet. The world's first processor was built by Intel company in 1970.

The CPU follows and controls instruction coming from any software or hardware. The CPU mainly consists of 2 parts.

Arithmetic and Logical Unit

Control unit

Arithmetic and logical unit calculates both data (numerical or logical data) and makes decisions.

It processes addition, subtraction, multiplication, division as well as logical data (<=> and, or). Control unit controls all the functions of the system.

Controls the work of all its parts like input, output, processor.

Output device

After the data has been processed in the system, the devices that the system uses to display the results by outputting the results are called output devices.

The output device provides data to the user in the form of sound, video, shape, photo etc.

In the output device, we all know the monitor, printer, earphone, speaker. It is visible by outputting us in all the device information.

Here I am telling you some important output devices. Monitor, Speaker, Printer, Projector, etc.

Hard Disk Drive

Hard disk acts as the storage of a system. That is, all the data, such as videos, MP3, documents, where all the files are saved, are called hard drive. This is a permanent storage device. In which you can store and keep data for as long as you want.

RAM (Random Access Memory)

RAM is also called main memory or primary memory or volatile memory. It is called volatile memory because it stores data temporarily.

Its full form is Random Access memory. RAM increases the speed of the system. Therefore, the higher the capacity RAM, the more speed the system will work.

Power supply

SMPS (Switched Mode Power Supply) is an electrical device that supplies power to all parts of the system.

Who invented computer - Father of Computer 

Its invention is one of the largest inventions in the world. Because it changed the whole world. All work is now done from this. This has made human work very easy.

Do you know who invented it and who is the father of it. If you do not know, then know that the person who invented it is named Charles Babbage.

Charles Babbage is said to be the father of this, who built a mechanical computer called "Differential engine" in 1822.

By the way, many people have contributed with time to develop or develop it. In 1837, he introduced the first modern system to the world as Analytical engine.

The Analytical engine used ALU (Arithmetic and Logic unit), basic flow control and integrated memory. Today's systems are also built on the basis of this model. This is the reason why he is called the father of the modern age system.

Broadly is divided into 3 categories based on its working. Each of which has its different types.

Analog - Systems that use an analog signal to show information are called Analog computers. The information contained in this is in continuous form which is shown as curves.

It is used in measuring continuous physical quantity such as temperature, electric current, blood pressure and heart rate.

Digital - Systems that use binary digits to show different information are called digital computers. Information in this is in discrete form. It handles information in the form of text, picture and graphics.

Hybrid - Such systems which are capable of understanding analog signals as well as binary digits to show the information, we know on the basis of Hybrid computer.

It shows information according to the operating mode. In this, the information is in continuous form as well as in discrete form as it does digital processing as well as analog processing.
