Today, if we hear the name of computer, then different types of thoughts come in our mind because this device is the only device for which it is obvious to generate thoughts in the brain. That is why it is important to know that What is the history of computer?
because today use of computer has brought a revolution in the world.
Today it is being used in a very important way in different areas of every country of the world (eg business, media, industrial, defense etc.) in government, non-government offices etc.
Today everyone is more dependent on technology and all this has been possible due to computer and its rapid development.
If you want to know about computer in a new way and in detail, then this article is going to be very important for you, so read it till the end.
Meaning of computer?
It is such an electronic device or machine that by forming the input data and instructions numerically and logically, gives the information in the output as a result. It does the work of hours in minutes.
It is also used for typing documents, sending mail to someone, playing games and entertainment etc.,
At present, humans have reached the moon and Mars, all this has happened through technology, which has been possible through computer, all this is the result of the hard work of scientists.,
Some links related to computer
The history of computer is very old. It is about 2500 years old. If we look at the basis of some evidence, then it is about 3000 years old.
It first started in China as Abacus. Such small devices were invented. Then gradually various changes and improvements were made in these devices, then only the “modern computer” could be built.
The detailed information about the efforts, experiments etc. involved in its creation is known as “History of Computer”.
Abacus was first invented in China. It was a calculation machine. It consisted of a wooden rack or frame in which two wires were attached.
These two wires were in parallel to each other. Baked clay balls were threaded in these wires, which were calculated by moving up and down or here and there.
It was used by traders to calculate their business because addition, multiplication, subtraction, division were easily done by this machine.
Even today its modern form is used in China, Japan, Germany and various countries of Asia.
Blaise Pascal or Pascaline
In the seventeenth century, there was a French mathematician and scientist named Blaise Pascal.
When he was only 19 years old, he invented a digital calculation device named Blaise Pascal in 1569 AD.
It was a mechanical digital calculator machine. This machine had a series of wheels in which numbers were attached which had to be dialed or rotated.
It is also called adding machine because it could only do addition.
This watch worked on the principle of V odometer. This machine is also called Pascaline.
It worked faster than the abacus. Pascal was the first modern scientist to develop a calculator.
This instrument was also invented in the seventeenth century by an English mathematician John Napier in 1617 AD.
It was this calculating device which was named Napier Bones.
It was a rectangular machine used for addition, multiplication, division etc.
Napier ji has made an important contribution in the development of computer. It is very famous because of its invention “Log Earthheim”.
Their logum was used to solve any complex problem in a very short time.
Weaver Joseph Jaccard invented a device in 1801 that controlled the design with punched punchcards.
Jaccard was a French scientist.
The specialty of this device was that it used to make fabric designs from punched punchcard patterns of cardboard. The threads were dictated by the presence and absence of pictures on the punch card.
Analytical and Differential Engine
Charles Babbage is considered the father of the modern computer. Taking inspiration from Pascaline, he invented an engine in the year 1922, which we know as Analytical and Differential Engine.
He built many such machines which could calculate correctly.
He was the first to build a common computer in the form of an analytical engine, on the basis of which today’s computer is built.
That is why he is also called the father and father of computer.
He was a British mathematician.
He envisioned a computer that could be automated but he could not complete it, which was completed by the salt scientist Harthan Hollerith.
Development of computer on the basis of generation
Now in our next article, we will tell you the development of computer on the basis of generation, which is as follows:
The first huge computer was started.
It lasted from 1940 to 1957. The size and shape of the computers of this generation were very large. It used to be equal to the room.
There was a lot of fear of breaking them. They used to emit a lot of heat, so they needed more cooling.
Their main equipment used to be vacuum tubes and magnetic drums. In this type of computer, 0 and 1 were used as language coding. The first computer of this generation was Inik.
This generation lasted from 1947 to 1963. In this generation of computers, transistors were used instead of vacuum.
It used to be a little light.
Some were better than them and were also smaller in size than the first generation, as well as they emit less heat than the earlier computers and their working speed was also faster.
Integrated circuits have been used in this generation. In this chip was used instead of transistor.
It was made of silicon metal. In this generation, better lighter, more efficient and faster computers were made from both the generations.
Computers of this era were much more reliable and capable of running more and more programs at the same time.
Computers of this time were mainly used as personal computers. This generation lasted from 1963 to 1971.
The time of this generation is from 1971 till now. The people who are using the computer today, it has been going on since this time.
Even today, the laptop we keep in our lap is the result of the hard work of this generation. Due to the use of microprocessor, its size has become quite a concern, due to which we can take it anywhere with us.
First of all, the best of all generations, small in size, shape and fast paced. This generation technology is called VLSI (Very Large Scale Integration).
This is the next generation, which is completely based on the future, so obviously its computers also depend on the future.
Work is going on on this right now and to some extent success has also been achieved. These computers are based on Artificial Intelligence.
They will be able to do their work on their own. USLI (Ultra Large Scale Integration) technology is being used in these. You can see this type of technology in machines like robots etc.
computer in india
The credit of bringing computers to India goes to Dr. Davis Dutta, by whom it was first brought to the Indian Institute of Science, Kolkata in 1972. It was an analog computer.
But the computer really started in India from the year 1956, the first electronic computer and digital computer HEC-2M was brought inside Kolkata Indian Institute of Science.
With the advent of this computer, India had become the second country in Asia after Japan that had used computer technology.
Then after some time, in 1958, a computer named “URL” was installed in the Indian Statistical Institute of Kolkata.
It was bought from Russia.
It was bigger than “HEC-2M” in size.
Till now all the computers used in India were bought from other countries.
Then in 1966, two institutions of India (Indian Statistical Institute and Jadavpur University) together made a computer in India which was named “ISIJU”.
It was a transistorized computer and after that gradually computers started being made in India itself.
The first supercomputer in India was made in the nineties in the year 1991, which is known as “Param-8000”.
Today big and latest computers in India are made by big and good companies.
Today India has many more supercomputers which are more powerful and capable than this.
But the talk of Param-8000 was different, due to which the digital world started in India.
It increased so much confidence that India made many more supercomputers.
Computer is creating a new revolution day by day all over the world.
Its use is increasing in every field, so it has become very important for everyone to have proper knowledge about computer. Because now everyone uses it in daily life, then of course it is necessary to have complete information about it.
Keeping these few things in mind, today through this article we have What is the history of computer? Been informed about this from the beginning till now.
