what is a computer, its utility and features
Let's know what the computer is? The computer is a machine that processes instructions to calculate, store, and manage data. Computers are made up of hardware and software. Computer is derived from the word, Latin word"computare". This means Calculation or compute.
It has three tasks from the main tor. The first is to take data, also known as Input. The second task is to Processing that data and the job is to show the data processed which is also known as Output.
Charles Babbage is the father of modern computers. Because it was he who first designed Mechanical computer, also known as Analytical Engine. It insert data with the help of Punch Card.
So we can call a computer a advanced electronic device that takes raw data from User in the input tor. Then processes that data through program (set of Instruction) and publishes the end result as Output. It process both numerical and non numerical (arithmetic and Logical) calculation. Hopefully you must have liked what happens to the computer.
what is the full form of the computer?
technically, there is no full form of computer. yet there is a hypothetical full form of the computer,
if you translate it into hindi, something like this will happen, common operating machines are especially used for business, education and research.
how do you run a computer?
for some people, using a computer can be hard to understand. this section will help you understand how to operate your computer easily.
you must be wondering how you can use keyboards and icons at the same time? well, it's not so complicated! here are some instructions on how to do this:
- move the mouse pointer to the icon or letter you want to click on.
- press and hold the left mouse button.
- drag the pointer to the location where you want to click.
- leave the left mouse button when you reach the desired destination.
computer history
this cannot be accurately evidenced as to when the computer development was started. but the development of officially computer has been classify according to the generation. they are divided into 5 parts from the main tor.
When it comes to generation Computer, it means that Computer's generations in hindi. As the computer develop, they are divided into different generations to make it easier to understand them properly.
1. First Generation of Computers – 1940-1956 "Vacuum Tubes"
First, generation's computers used to circuitry Vaccum tubes and memory Magnetic Drum. They used to be quite big in size. A lot of power was used to run them.
Being too big, it also had a lot of heat problems that sometimes malfunction. They used Machine Language. for example , UNIVAC and ENIAC computers.
2. Second Generation of Computers – 1956-1963 "Transistors"
transistors replaced vaccum tubes in the computers of the Second generation. Transistor used to take very little space, were small, faster, cheap and had more Energy Efficient. They used to heat generate less than generation computers, but still had heat problems.
These included COBOL and FORTRAN like High Level programming Language.
3. Third Generation of Computers – 1964-1971 "Integrated Circuits"
Integrated Circuit was first used in Third generation's computer. In which Transistors was smallly inserted into the silicon chip called Semi Conductor. This helped to greatly increase the computer's ability to processing.
For the first time, Monitors, keyboards and Operating System were used to make the computers of this generation more user friendly. It was launch in Market for the first time.
4. Fourth Generation of Computers – 1971-1985 "Microprocessors"
The specialty of the Forth generation is that it used Microprocessor. Thousands of Integrated Circuit were embedded in the same silicon chip. This made it very easy to reduce the size of the machine.
The use of Microprocessor added to the efficiency of the computer. It was a very useful task to do big calculations.
5. Fifth Generation of Computers – 1985-present "Artificial Intelligence"
Fifth generation belongs to today's rope where Artificial Intelligence has dominated. Now many advanced technologies such as new Technology such as Speech recognition, Parallel Processing, Quantum Calculation are coming into use.
These are generation where the computer has Artificial Intelligence and has the ability to take decision itself. Gradually all its work will be Automated.
who invented the computer?
What is called the father of modern computers? So many people have contributed to this Computing Field. But more of all this is the contribution of Charles Babage. Because he was the first to leave Analytical Engine in 1837.
The concept of ALU, Basic Flow control and Integrated Memory was introduced in his engine. It was on this model that the computer of today was design by Base. That's why his contribution is the highest. Only then is he also known as the father of the computer.
definition of computer
Many of any modern digital computers are components 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 used Input Device and put in the computer. It can also be a letter, a picture, or a video.
Process: Data input during Process are processing according to instruction. This is a completely Internal process.
Output: The data that have already been process during Output are show in the tor of the Result. And if we want, we can save this result and put it in the Memory for the use of Future.
named picture of basic units of computer
if you have ever seen within which computer case, you must have found that there are many small components inside, they look very complicated, but they are not that complicated in actually. now i'll give you some information about this components.

Motherboard
The main circuit board of any computer is called Motherboard. It looks like a thin plate, but it is worn by many things. For such CPU, Memory, Connectors hard drive and Optical Drive, to control expansion card Video and Audio, along with it connection all the Ports of the computer. Motherboard is connected to all parts of the computer directly or in directly.
CPU/Processor
Do you know what Central Processing Unit means CPU?CPU? This is also called. This computer is found in the Motherboard inside the case. It is also known as the brain of the computer. It is keeping an eye on all activities within a Computer. The more a Processor is speed, the sooner it will be able to processing.
RAM
We also know RAM as Random Acess Memory. It is the Short Term Memeory of System. Whenever a computer does some calculations, these temporarily save that result into RAM. This data is also lost if the computer is turned off. If we are writing a document, we must save our data in the beach to avoid it being destroyed. Save can last longer if it save in Data Hard Drive.
RAM are measured in megabytes (MB) or gigabytes (GB). The more RAM, the better we are.
Hard Drive
Hard Drive is the component where software, documents and other file are save. It has a long store data.
Power Supply Unit
Power supply unit is to take power from Main Power Supply and Supply it to another components as needed.
Expansion Card
All Computers are Expansion Slots so that we can add a Expansion Card in the Future. These are also known as PCI (Peripheral Components Interconnect) card. But in today's Motherboard, there are built in many Slots already. Some Expansion Card names which we can use to update old computers.
- Video Card
- Sound card
- Network Card
- Bluetooth Card (Adapter)
computer hardware and software
Computer hardware we can call a Physical Device we use on our computers, the same Computer Software means the collection of codes that we install in the Hard Drive of our Machine to run hardware.
For example, computer monitors that we use to fall, Mouse we use to Navigate are all Computer Hardware. The Internet Browser we website visit, and the Operating System that Internet Browser run. Such things are called Software.
We can say that a computer is a combination of Software and Hardware, both have similar roles, both can do a job together.
