The original meaning of computer is "calculator", that is to say, human beings will invent computers with the initial purpose of helping to deal with complex digital operations. The concept of manual calculator can be traced back to Pascal, a great French thinker in the 7th century. Pascal's father is the tax director. At that time, the monetary system was not decimal, so it was very troublesome to calculate. Pascal used the gear principle to assist his father and invented the first calculator that can add and subtract. Later, the German mathematician Leibniz improved it and invented a calculator that can do multiplication and division. After that, although the function of the calculator was improved and refined, the real electric calculator could not be manufactured until AD 1944.
The first machine that can really be called a computer was born in the United States in 1946. It was invented by Mao Qili and eckert, and its name is ENIAC. This computer uses vacuum tubes to process signals, so it is huge (occupying one room) and consumes high power (everyone in the town knows when to use it, because the lights in every household are dimmed! ), and the memory capacity is very low (only 100 words), but it is already a great progress in human science and technology. And we usually call this kind of computer using vacuum tube the first generation computer.
The first generation computers were as big as two classrooms and much smaller than the personal computers we usually use now. At that time, the computer part was a vacuum tube (now I can't find it), and what was archived was punch cards. Without the design concept of predecessors and the invention of computers, it is still difficult to define who invented computers.
Question 2: What was the name of the first person who invented the computer? Who invented the computer? Strictly speaking, it is difficult to define.

Pascal has always been recognized as the inventor of the first gear computer in the world, and he is extremely proud of this achievement. But before Pascal was invented, the German mathematician Kasher had designed and manufactured a 6-digit gear computer. Kashe is a famous oriental linguist and mathematician. He also has a deep study of astronomy. He is often trapped in a large number of data calculations and exhausted by complicated calculations. The problems in reality prompted him to create a new and effective calculation tool to reduce the heavy calculation burden. 1623 began to conceive the design, made a prototype in the same year, and made some improvements later. The principle of this computer is similar to Pascal's, and it is easy to break down during use. Historically, people knew little about the computer invented by Casher, and its social impact was minimal. It was not until 1958 that people learned that he invented the gear computer in relevant historical materials. Therefore, when we talk about the first invention of gear computer, we can't help but mention Casher. In fact, Casher was the first inventor of the gear computer.

Without the design concept of predecessors and the invention of computers, it is still difficult to define who invented computers. Although the famous scientist John? Newman (john von neumann; ; Von Newman is often called "the father of modern computers" by later generations because of his talent in the field of science. However, von Newman? K is not the real inventor of modern computers. This glory should be attributed to design? Who made the first digital electronic computer ―― John? Moakley and Preston? Chairman eckert. The legend that they built the first computer in just three years and fought for it in the next 30 years is a story of outstanding wisdom and deep regret. Who invented the computer? In computer class, it is likely that the teacher will say: The world's first electronic computer, called "Eniac" (originally Eniac, translated into Chinese earlier as "ilium"), was invented by Americans Morceli and eckart Kee in 1946. If you take the computer knowledge test, there is nothing wrong with this answer; But if you tell others about computer history, it is wrong to say so. Because that's not the case. As early as 1947, the year after Enyak appeared, Mocelli and eckart filed a patent application with the US Patent Office, but the patent was released late in 1964, because the Patent Office still had doubts about their idea of "the world's first electronic computer". Moreover, after the publication of the patent, Hanniwei Company of the United States still produced the patent without purchasing it from the patentee, so the company was accused of violating the patent law. However, Hannibal refused to accept it. They think that the real inventors of electronic computers are not Mocelli and eckart, but atanasoff. So the lawsuit went to court. After125th session, the court finally announced in 1973, 10, 19: "Mocelli and eckart didn't invent the world's first electronic computer, but used the idea invented by atanasoff ..." Atan nosov is a physicist working in the University of Iowa. The heavy calculation process in the research made his life difficult, so he decided to engage in the research of electronic computers. 1937 One night in winter, he was depressed, because a difficult problem in his research bothered him and could not be solved, so he drove to a roadside pub in Illinois for a drink to relieve boredom. After he drank two glasses of wine in a row, the method of using capacitor as memory element to regenerate memory suddenly flashed in his mind, and thus the most primitive concept now called "logic circuit" came into being. Starting from this initial idea, after two years of hard research and experiments, the world's first electronic computer with binary logic operation as its core was finally made in193965438+February. However, it was World War II and the University of Iowa did not apply for a patent. Later, it was not made public ... >>
Question 4: Who invented the first computer in the world? Who invented the first electronic computer in the world? The inventors of electronic computers mentioned in textbooks in China, most academic works and scientific popularization works are not real inventors. The real inventor is American John? Professor atanasoff.
Most books say that American Hungarian scientist von? John von neumann (1903- 1957) is the inventor of electronic computer, and has always been known as "the father of electronic computer". However, what about Feng? Neumann himself does not consider himself "the father of electronic computers". American physicist, who worked as von in Los Alamos laboratory? Frankl, Neumann's assistant, wrote in the letter: "Many people recommend Feng? Neumann is the "father of computers", but I'm sure he has never made this mistake himself. Maybe he can be properly called a midwife. But he once told me, and I believe he also told others that the basic concept of computer belongs to Turing if the related concepts put forward earlier by Babbage and Ada are not considered. In my opinion, Feng? Neumann's basic function is to let the world know the basic concepts introduced by Turing. " Is it Feng? Neumann himself personally transferred the title of "Father of Computers" to British scientist Allen? Turing (Allen M. Turing, 19 12- 1954). However, the real "father of computers" is neither Feng? Neumann, not Allen? Turing
Before 1973, most people in the computer field in the United States believed that the inventors of electronic computers were J. Mauchiy and P. Acott from Moore School of Electrical Engineering, University of Pennsylvania, because they were the developers of the first electronic computer ENIAC (Eniac) with great practical value.
It is now recognized by the international computer community that the real inventor of the first electronic computer was John? Vincent. Atanasoff (John v atanasoff, 1903- 1995). In the international computer world, he is called "the father of electronic computers". Unfortunately, most people in the computer industry in China don't know this fact.
About who is the real inventor of electronic computer, American related persons atanasoff, Mochili and Acott once fought a long-running lawsuit, and the court heard it 135 times. Finally, a district court in the United States made a judgment. 1973 10 19. The court announced the verdict in public: "Mochili and Acott didn't invent the first computer, but only used the idea invented by atanasoff." The reason is that as early as 194 1, atanasoff told the inventor of ENIAC what Mochitari thought about electronic computers.
J.Atanasoft is a professor of physics at the University of Iowa. Atanasoff is a graduate student of Clifford? The electronic computer was invented with the help of Clifford E. Berry.
The first experimental prototype of electronic computer was put into operation in June 1939+00. This computer helps professors and graduate students at the University of Iowa solve some complicated mathematical equations. Atanasoff named this machine ABC(Atanasoff- Berry-puter), where A and B take the initials of their surnames respectively, and C is the initials of "computer".
After the birth of the first electronic computer, atanasoff and Berry didn't get the inventor's wreath.
Before atanasoff and Berry left, two improved ABC computers were already running. These two ABC computers are stored in the storage room of the physics building of the University of Iowa and gradually forgotten. 1946, due to the shortage of materials, both machines were dismantled, and the parts were used for other purposes, leaving only the memory part. The University of Iowa did not apply for a patent for ABC computer, which brought a long-lasting legal dispute to the invention right of electronic computer. The US District Court's ruling is correct, because the inventor of ENIAC, Mocelli, did visit the ABC computer of the University of Iowa and listened to atanasoff's introduction, which inspired him.
Atanasoff was born in Hamilton, Maryland, USA on 19031October 4th. He spent his childhood in Florida. His father is Bulgarian, won the highest scientific prize in Bulgaria and went to ....................................................................................................................................................... & gt
Question 5: Who created the computer? Hello.
Computers can't be said who created them, just like clothes. At first, people had no clothes to wear, then they covered themselves with leaves, and then they covered themselves with thick ropes until clothes made of cloth appeared. So clothes were not created by one person.
The same is true of computers, which are developed step by step.
As early as 1642, the French philosopher Blaise Pascal invented the first mechanical addition calculator to help his father solve the tax calculation.
1833, Babbage designed a new analyzer, which can not only complete arithmetic operations, but also include input, control, operation, storage and output devices.
193 1 year, many scientists developed a "differential analyzer" together, which is considered as a pioneer of computers.
1938, many scientists invented a computer that works with relays.
1942, many scientists invented the first vacuum tube computer.
1943, many scientists invented the first programmable computer.
1946, many scientists invented the first electronic digital integrated computer, which was built by Eniak. This computer is very big, as big as four houses, and consumes a lot of power.
Later, the computers made became smaller and smaller, and gradually became the computers we use now. In the future, computers will also change.
Question 6: Who invented the computer? To be exact, the current computer network was not invented by someone, because the original intention of their invention was not that the computer in the present sense was a copy of the American defense network. Computers are not powerful, but the Internet is. The first personal computer was produced by ibm, and the computer came into being. Of course, a computer won't do. The most important thing to make the computer run is that the operating system has cooperated with Bill Gates since ibm, and now more than 99% users in the world are using Microsoft system. Today's computers are a combination of hardware+software+Internet, and one of them is waste.

Remember to adopt
Question 8: Who is the inventor of the computer? The scientific name of computer is electronic computer, which is developed from the early electronic calculator. From 65438 to 0946, the first electronic digital computer "ENIAC" appeared in the world, which was used to calculate the trajectory. It is manufactured by Moore Institute of Electrical Engineering, University of Pennsylvania, USA, but it is huge, covering an area of 170 square meters, weighing about 30 tons, and consumes nearly 100 kilowatts of electricity. Obviously, such computers are expensive and inconvenient to use. 1956, the transistor electronic computer was born, which is the second generation electronic computer. Only a few larger cabinets can be installed, and the operation speed is greatly improved. The third generation of integrated circuit computers appeared in 1959. The original computer was made by John? Feng? Invented by Neumann (at that time, the computing power of computers was equivalent to that of today's calculators), which was as big as three warehouses, and gradually developed.
Question 9: Who invented the notebook computer? What country are you from? The inventor of the first notebook computer was not Toshiba, nor Apple or IBM, but a company called "Osborne Computer", whose founder was Adam? Adam Orn.
1981April, Osborne Company invented the world's first notebook computer, and Adam, the founder of Osborne Company, led the research and development. Osborne used to be a journalist, but later he abandoned his pen and went into business. Once upon a time, Osborne was considered to be with Microsoft founder Bill? Bill Gates and Apple founder Steve? Steve Jobs is equal. Osborne Computer Company is also the fastest growing company in the history of Silicon Valley. However, due to the advanced concept, the company fell apart in less than 30 months of operation. Osborne made many wrong promises in technology, and the product release date is far away. Now the industry calls this situation "Osborne effect".
As the first notebook computer in the world, Osborne 1 weighs 20 kilograms and has no battery, so it is not portable at all according to the present eyes. However, compared with the personal computer that was a giant at that time, the Osborne 1 model was much smaller, and people could put it in a box and carry it with them. In addition, Osborne 1 was the first computer with practical software, which was surprisingly cheap at that time, as long as 1795 dollars.
