What is Computer
A computer is a machine that performs tasks according to certain instructions. There is an electronic device, which is designed to work with information. The word computer is derived from the Latin word "computare". This means Calculation or calculating.
It has three main functions. The first is to take the data which we also call Input, the second task is to process that data and the last task is to show the processed data which is also called Output.
Computer Working Process
Input Data → Processing → Output Data
Who invented computer? The father of the modern computer is called Charles Babbage. Because he was the first to design a mechanical computer, which is also known as Analytical Engine. In this, data was 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 finally the result as Output Publishes. It processes both numerical and non numerical (arithmetic and logical) calculations.
What is the full form of Computer
Technically does not have a full form of computer. Yet there is a fictitious 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 - Generation of Computer
It cannot be properly verified that the development of computers has been started since. But officially computer development has been classified according to generation. They are divided into 5 parts from the main tower.
When it comes to the generation of computer, then it means that computer's generations. As the computer grows, they are divided into different generations to make it easier to understand them properly.
First Generation of Computer - 1940-1956 "Vacuum Tubes"
The first generation computers used Vaccum tubes for circuitry and Magnetic Drum for memory. They used to be very big in size. A lot of power was used to run them.
Being too big, it also had a lot of heat problem due to which it was also malfunctioned many times. Machine language was used in them. For example, UNIVAC and ENIAC computers.
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 were used in them.
Third Generation of Computers - 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.
Fourth Generation of Computers - 1971-1985 "Microprocessors"
This is the specialty 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 very work was able to do a lot of calculations.
Fifth Generation of Computers - 1985-present "Artificial Intelligence"
Fifth generation belongs to today's Dor, where Artificial Intelligence has established its dominance. Now, many new technologies like Speech recognition, Parallel Processing, Quantum Calculation are being used in the new technology.
This is a generation where due to the computer's artificial intelligence, the ability to make decisions on its own has come. Gradually all its works will be automated.
Who invented Computer
Who is called the father of modern computer? Many such people have contributed to this Computing Field. But more of all this is contributed by Charles Babage. Because he was the first Analytical Engine came out in 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 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.
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.
images of the Part of the Computer
If you have ever looked inside a computer case, then you must have found that there are many small components inside, they look very complicated, but they are not really that complicated. Now, I will give you some information about these components.
Part of the Computer
Motherboard
The main circuit board of any computer is called the motherboard. It looks like a thin plate but it holds many things like CPU, memory, connectors for hard drive and optical drive, to control expansion card video and audio, along with all of the computer Ports connection. If seen, the motherboard is directly or in directly connected with all parts of the computer.
CPU / Processor
Do you know what is Central Processing Unit i.e. CPU? It is also called. It is found in the motherboard inside the computer case. It is also called the brain of the computer. It keeps an eye on all the activities that are within a computer. 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. If the computer is shut down, then this data is also lost. If we are writing a document, then to save it from being destroyed, we should save our data in between. If saved in Data Hard Drive by saving, then it can remain for a long time.
RAM is measured in megabytes (MB) or gigabytes (GB). The more RAM there is, the better 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.
Names of some Expansion Cards that we can use to update old computers.
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 computer 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 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. They come in various shapes and sizes. We use them as per the requirement, such as ATM to withdraw money, Scanner to scan a barcode, Calculator to do a big calculation. These are all different types of computers.
1. Desktop
Many people use desktop computers for their homes, schools and their personal work. They are designed in such a way that we can keep them on our desk. They have many parts such as Monitor, Keyboard, Mouse, Computer Case.
2. Laptop
You must have known about laptops which are battery powered, they are very portable so that they can be taken anywhere and anytime.
3. Tablet
Now let's talk about the Tablet which we also call Handheld Computer as it can be easily caught in handguns.
It does not have Keyboard and Mouse, just a touch sensitive screen which is used for typing and navigation. Example- iPAD.
4. Servers
A server is a computer of some sort that we use to exchange information. For example, whenever we search for something in the Internet, all those things are stored in the server.
5. Mainframe Computer
A Mainframe Computer is faster and more efficient than all the computers mentioned above. They are used by government establishments, big companies to store data. These computers are very large in size.
6. Analog Computer
Analog Computer is a machine that displays data in a physical quantity (pressure, temperature, length, height, etc.), these data are constantly (continuously) changed. The functionality of Analog Computer increases. We get the result of these in the form of graph etc. Analog Computer cannot store statistics. They are used in the fields of technology, science, education etc. Thermometers are an Analog Computer.
7. Hybrid Computer
These computers are characterized by an Analog Computer and a Digital Computer. Hybrid Computer is faster than both these types of computers and results are pure. In these computers, Digital Computer is meant to do a regular and numerical task, while Analog Computer solves the problem. They are used in the areas of complex mathematical equations, scientific calculations and defense etc. Patrol Pump Machine, Speedometer etc. are easy examples of Hybrid Computer.
8. Micro Computer
Microcomputer is a fast growing and widely used computer. It is cheaper and lighter than all types of computers. It is also the smallest in size. This type of computer has been developed for general purpose like entertainment, education, home and office use etc. PCs, Notebooks, Laptops, PDAs (Personal Digital Assistants) etc. are Micro Computer.
Other types of Computer
Let us now know what other types of computers are.
Smartphone: When Internet is enabled in a normal cell phone, we can do many tasks using it, then such a cell phone is called a smartphone.
Wearable: Wearable technology is a general term for a group of devices - including fitness trackers and smartwatches - that are designed so that they can be worn throughout the day. These devices are often called wearables.
Game Console: This game console is also a special type of computer that is used to play video games on your TV.
TV: TV is also a type of computer which now includes many applications or apps that convert it into Smart Tv. Whereas now you can stream videos from the Internet directly to your TV.
