Who invented the computer? Please, thank you

The scientific name of the computer is the electronic computer, which was developed from the early electric calculator. In 1946, the world's first electronic digital computer "ENIAC" appeared for calculating ballistics. It is manufactured by the Moore Institute of Electrical Engineering of the University of Pennsylvania in the United States, but it is bulky, covering an area of more than 170 square meters, weighing about 30 tons, and consuming nearly 100 kilowatts of electricity.

Obviously, such a computer costs a lot and is inconvenient to use. In 1956, the transistor electronic computer was born, which was the second generation of electronic computers. It can be accommodated in just a few larger cabinets, and the calculation speed is greatly improved.

In 1959, the third generation of integrated circuit computers appeared. The original computer was invented by Johann von Neumann (at that time the computing power of computers was equivalent to today's calculators), the size of three warehouses, and gradually developed into an elite IT organization 乄 ip worm sincerely serve you If the problem is solved, please give me a problem"Positive reviews"！Thank you for your support

Who invented the computer is strictly difficult to define. The original meaning of computer was "calculator", that is, humans invented computers to help with complex number crunching. The concept of this artificial calculator can be traced back to the great French thinker Pascal in the seventeenth century.

Pascal's father was the tax collector, and the currency system at that time was not a decimal system, which was very cumbersome to calculate. In order to assist his father, Pascal invented the first calculator that could perform addition and subtraction, using the principle of gears. Later, the German mathematician Leibniz improved it and invented a calculator that could do multiplication and division.

Although the functions of the calculator were improved and refined in many ways, the real electric calculator had to wait until 1944 to be manufactured. The first machine that can really be called a computer was born in the United States in 1946, invented by Mao Qili and Eckert, and the name is ENIAC. The computer uses vacuum tubes to process signals, so it's bulky (it takes up a room) and consumes a lot of power (the whole town knows about it, because the lights in every house are dim!). , and the memory capacity is very low (only more than 100 words), but it is already a great progress in human technology. And we usually call this kind of computer that uses a vacuum tube the first generation of computers. The first generation of computers was the size of two classrooms, which was much different from the size of the personal computers we use today.

At that time, the computer parts were vacuum tubes (which can no longer be found) and the archive thing is a punch card, if there is no design concept of predecessors, there is no invention of the computer, so it is a bit difficult to define who invented the computer.

The first machine that can really be called a computer was born in the United States in 1946, invented by Mao Qili and Eckert, and the name is ENIAC.

For many years, people were accustomed to thinking of Mochley and Little Ecto, who launched ENIAC at the University of Pennsylvania in 1946, as the "fathers of the computer". Professor Yuan Chuankuan's remarks not only subverted the previous "consensus", but also made waves again on this old topic that had been silent for many years. On the afternoon of October 15th, John Atanasoff II was invited by Zhongguancun Innovation Institute to meet with a small number of ** in Beijing.

He is now primarily the CEO of a pharmaceutical company and the son of Atanasoff, the "father of forgotten computers." Yuan Chuankuan said that on the question of who invented the computer, more than 30 years ago, in 1973, there was a trial in the United States, which legally determined that Atanasov was the real inventor of the modern computer. Regrettably, to this day, this historical case is still little known to the Chinese people.

In 1937, Atanasov, then a professor of physics at Iowa State University, spent two years designing the basic principles and structure of an electronic computer in order to solve the heavy mathematical calculations in his daily work. In 1939, he teamed up with Clid Berry to develop a complete prototype known as ABC with a $650 university research grant. At that time, Atanasov was not fully aware of the market value of his invention and did not apply for patent protection for his invention.

In 1941, Mochly spent five days at Atanasov's house and stole the results of his research, creating ENEAC with Eckert. They then quickly applied for patents and became famous all over the world. In 1967, Mochley was brought to court.

On 19 October 1973, the final judgment of the Tribunal. Since June 1, 1971, 135 trials, 77 witnesses have been called in one trial, and 80 written testimonies have been collected during the deposition period by lawyers for both sides, making it the longest intellectual property lawsuit in U.S. history. Hu Bangchong Atanasov Jr. said that the purpose of today's repetition of the old words is to make a public response to people who do not know the inside story of China, and to take the opportunity to clarify some previous misunderstandings from the outside world.

His father was too old to devote more energy to publicity after the trial. Coupled with the fact that it happened to "collide" with another big news the next day, ** has a bit of a bad attitude towards it. However, the judge's decision has given a big boost to the computer industry.

According to Atanasov Jr., after Mochli's patent was declared invalid, a new situation opened up in the computer industry. A lot of new computer companies have sprung up because they don't have to pay huge licensing fees. He also noted:

After winning that lawsuit, no one really controls the computer patents, which is a good thing for the industry. The truth is still in its shoes, and rumors are already flying. Zhang Kezhao, director of the computer science department at Iowa State University, said that Atanasov Jr.'s family has no connection with computers at present, and the "correct name" of annihilating China this time is completely moral, and will not have any economic benefits for them. Beg.

In 1940, Walter Aiken of the United States built the first new type of computer, which was designed and developed in 1945 by two professors at the University of Pennsylvania, Mochley and Eckert.

The computer was invented by a person in the United States.

Feng. Neumann! Just this kid invented it, what's the use of talking so much upstairs? I didn't say the point!
