Introduction to Computer

picture of computer

Many people would not know computer. So here we will introduce you to Computer. There will be many such people. Who must have heard the name of computer. You must also know what a computer is. But really do not see the computer. Similar people keep searching the picture of computer on Google. So above we have shown the picture of computer. Which you can understand by seeing what a computer is like. However, according to the type of computer, the size and design of the computer also changes. But here we have told the original computer which is called Desctop. It consists of a monitor, CPU, keyboard and mouse. These are all different. It is connected to each other by wire.

Computer is an electronic device consisting of two parts software and hardware. The part of the computer that can be seen and touched. It's called hardware. The part of the computer that cannot be seen or touched. It is called software. Software is a set of instructions or programs. Which are stored in the computer's storage device. Their job is to manage the hardware and tell the hardware what to do. Computer hardware is also made up of many tools.

Let us know all these in detail, which part of which computer hardware device comes in.

1. Input Device

The computer device used by the computer user to give instructions to the computer. All those devices are called input devices. As; Keyboard, mouse, microphone etc.

2. Output Device

The device used by the computer to show or tell the results by the computer to the computer user. It is called Output Device. As; Monitor, Speaker, Printer etc.

3. Storage Device

Computer device that stores instructions, information and data What-is-computer. It is called a storage device. Storage device is commonly known as memory. As; Hard Disk Drive, DVD Drive etc.

4. Processing Device

The device which the computer uses to decide the result of the instruction given by the computer user to the computer. It is called Processing Device and this action is called Processing. The following devices come under Processing Device. As; CPU, processor etc.

Functions of Computer

You must have read about the utility and features of computer. In which it is told where where the computer is used. What can you do with this? People know what they can do with computer. But many will not know the basic functions of computer. For your information, let us tell you that the computer has only four basic functions. On the basis of this computer does a lot of work. Let us know the basic functions of computer in detail. Following are the basic functions of computer.

Data Collection

Data Storage

Data Processing

Data Output

With this, you must have come to know that what is the power of computer and what work does the computer do. Let us know in detail about each and every function of computer.

1. Data Collection

The first and main function of computer is data collection. The computer collects the data before giving the result. Until this data will not be given. Till then it will not give any result. Input device of computer is used to give data to computer.

2. Data Storage

When any data is given to the computer. Then the computer stores that data. When the result of input data is received. Then the computer can store that result also for future. Computer uses storage devices to store data.

3. Data Processing

The important function of computer is processing. Computer does processing before giving any result. Proper result of input data is obtained during processing. Computer uses Processor (CPU) to do data processing.

4. Data Output

Data Output is the last function of the computer. When any data is given to get the result from the computer. Then the computer processes that data and gets the proper result. Now the result has to be shown or told to the user. Output device is used to show or tell the result to the user.

How does computer work?

You must have known what a computer is. Must have also become familiar with computer. Let us now understand its working method. Computer cannot understand the instructions given by us. Because we give instructions to the computer in our language (eg; Hindi, English, Telugu etc.). But the computer does not understand our language. Computer is a machine. That's why it comes only to Machine Language. Which is in the form of 0 and 1. Every electronic device functions as a 0 and a 1. Which are called Binary Digits. You can call it the mother tongue of machines or the natural language of computers. In which 0 means Off means off and 1 means On means on. Which is also called Binary Language. Apart from this language, computer does not know any other language.

Computer works on the basis of this language. All the work in the computer is done in the form of Binary Digits. If you are watching something on computer. As; Videos, images etc. Then it is also present in the computer in the form of Binary Digits. But you can see and understand it in your language with the help of any device. This is because it is programmed that way. Similarly, the instructions we give to the computer with the help of Input Device. That too goes in the form of Binary Digits in the computer. All this work is done by the translator. Which turns our language into machinery language. Although the computer can be instructed directly through Binary Language.

But this task is a very difficult one. Because learning it, writing programs in it, testing and debugging is a difficult and flawed task. Therefore, over time, many artificial computer languages were invented. Today High Level Computer Language has also become. With the help of which it is easy to give instructions to the computer. Because this language is similar to the common English word. Computer requires software to function. Which is made from computer language itself. Input device, storage device, processing device and finally output device are required respectively for the computer to function. Receives instructions from the input device, stores the instruction from the storage device, processes the instruction from the processing device and finally provides the result of the instruction from the output device.

How to Operate Computer

First of all, instructions are given in the computer program to make the computer workable. Computer works on the basis of this instruction. A special language is used to give instructions in computer programs. Which is called computer language. It is also called programming language. After this the computer becomes workable. Now even a normal person can operate this computer. To operate the computer, three processes have to go through. First is input, second is processing and finally output. Let us know the three steps in detail.

1. Input

This is the first process to operate the computer. In the first process, instructions have to be given to the computer. Which is called Input. You can give any type of data as input to the computer. But keep one thing in mind that the figure you will give. Computer will work for the same. Input device is used to give input to the computer. As; Keyboard, mouse, microphone etc.

2. Processing

This is the second process of operating the computer. In this process the computer processes the instruction to get the result. Which is called Processing. That is, you do not have to do anything in Processing. This work is done by the CPU of the computer. That is the tool. which determines the outcome of each instruction.

3. Output

This is the final process of operating the computer. In this process the result of processing the instruction is shown or told. Which is called Output. The computer shows or tells the output of each instruction through the output device. As; Monitor, Speaker, Printer etc.

Let us try to understand its process with an example. As; You want to turn on the computer. Then first of all the button to turn on the computer has to be pressed. When you press the button to turn on the computer. Then it is received in the form of input to the computer. The computer processes this input from the CPU and gives it as output (result) by turning the computer on.

Types of Computer

By the way, many and many types of computers have been made. By saying many types, I mean the type of computer. Like the Smartwatch you use today. That too is a computer.
