What is a computer and its features?

A computer is a machine that performs tasks according to certain set instructions. This is electronic device, which designed to work with information. The word computer 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 to process that data and the other task to show the processed data which called Output.

Input Data → Processing → Output Data

The father of modern computers called Charles Babbage. Because he was the first to design a mechanical computer, which also known as Analytical Engine. In this, data 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. Then processes that data through a program (set of Instruction) and publishes the final result as Output. It processes both numerical and non numerical (arithmetic and logical) calculations.

What is the full form of Electronic computer?

Technically there is no full form of computer. Yet the computer has an imaginary full form,

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

If you translate in Hindi, then it will be something like this, the common operating machine specially used for business, education and research.


It cannot be properly verified that the development of computers has started since. But officially the development of computers has been classified according to the generation. They divided into 5 parts from the main tower. When it comes to the generation of computers, it means that computers generations in Hindi. As the computer grows, they divided into different generations to make it easier to understand them properly.

1. First generation of electronic computer – 1940-1956 “Vacuum Tubes”
The first generation electronic computers used Vaccum tubes for circuitry and Magnetic Drum for memory. They used to be very big in size. A lot of power used to run them.

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

2. Second generation of computers – 1956-1963 “Transistors”
In second generation computers, transistors replaced vaccum 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 ​​like COBOL and FORTRAN used in them.

3. Third Generation of Computer – 1964-1971 “Integrated Circuits”
Integrated Circuit was first used in third generation computers. In which the transistors were cut into small silicon chip which is 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 launched in the market for the first time.

4. 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.

5. Fifth Generation of Computer – 1985-present “Artificial Intelligence”
Fifth generation belongs to today’s Dor, where Artificial Intelligence has established its dominance. Now many new technologies such as Speech recognition, Parallel Processing, Quantum Calculation have come into use with new technologies.

This is a generation where due to computer 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 called the father of modern computer? Many such people have contributed to this Computing Field. But most of all these contributions are from Charles Babage. Because he was the first Analytical Engine came out in the year 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 the reason 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 but 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 a completely 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.

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

CPU / Processor
Do you know what is Central Processing Unit i.e. CPU? 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 memeory of the system. Whenever the computer does some calculations, it temporarily saves that result in RAM.

RAM is measured in megabytes (MB) or gigabytes (GB). The more RAM there is, the better it is 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 slots built-in. Some Expansion Card names that we can use to update old computers.

Video card
Sound card
Network card
Bluetooth Card (Adapter)
Note
If you are ever opening things inside the computer, then you should first remove the plug from the main socket.

Electronic Computer hardware and software
We can call 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 electronic computer is a combination of software and hardware, both have the same roles, both can work together.

Types of Computer

Whenever we ever hear the use of the word computer, only the picture of personal computer comes into our mind. Let me tell you that there are many types of computers.
