Who invented the computer?

Strictly speaking, it is difficult to define who invented the computer.

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.

How the computer was invented (process)

1672, 1 In June, Leibniz made a wooden machine model and showed it to the members of the Royal Society. However, this model can only explain the principle and cannot be realized normally. Since then, in order to speed up the development of computer programs, Leibniz lived in Paris for four years. In Paris, he cooperated with the famous watchmaker Olivier. He just needs to make a simple explanation to olivet, and the actual manufacturing work will be done by the watchmaker alone. 1974, the final machine was assembled by Hollibert alone. Leibniz's multiplier is about 1 meter long, 30 cm wide and 25 cm high. It consists of a fixed counter and a movable positioning mechanism. The whole machine is driven by gear system, and its important part is stepped shaft, which is convenient for simple multiplication and division operation.

The prototype of Leibniz's design was exhibited in Paris and London. Because of his outstanding achievements in computing equipment, he was elected as a member of the Royal Society. 1700 was elected as an academician of the Paris Academy of Sciences.

Leibniz was also the first person to realize the importance of binary notation, and systematically put forward the operation and calculation rules of binary numbers. Binary system has had a far-reaching impact on the development of computers after more than 200 years.

When Leibniz settled in France, he had close contact with Bai Jin, a missionary to China. Bai Jin once taught a math class to Emperor Kangxi. He is very interested in China's Book of Changes. 170 1 year, he gave Leibniz two maps of Yijing, one of which is the famous orientation map of Fuxi's sixty-four hexagrams. Leibniz was surprised to find that these sixty-four hexagrams correspond to sixty-four binary numbers. Leibniz thinks that China's gossip is the earliest binary notation in the world. So he published "On China's Philosophy" in 17 16, focusing on gossip and binary, and pointed out that binary and gossip are * * * similar.

Leibniz yearns for and admires the ancient civilization of China. He presented the replica of his instrument to Emperor Kangxi of China to show his respect for China.

When was the earliest computer invented?

1946 On February 4th, the world's first computer ENIAC was born in the University of Pennsylvania.

This computer has four classrooms, 170 square meters and weighs about 30 tons.

Nearly 20,000 electron tubes have been used, and the power consumption is staggering, which is equivalent to the power consumption of 3,750 40-watt lamps lit at the same time. But there are not many functions and the working speed is not fast!

How did the computer come into being?

The development history of electronic computers

Decimal counting method invented by China in the Eastern Han Dynasty; Abacus was invented in the Song Dynasty.

16 17 years, the Scottish inventor JohnNapier used bone tools for division, subtraction, addition and multiplication, and invented the slide rule.

1622 William Mutrade of England invented the sliding slide rule.

With Kepler's active participation, Shekel finally began to develop the first calculator with four functions of addition, subtraction, multiplication and division (computational clock) in 1624 at Heidelberg University. Unfortunately, the prototype model was destroyed by fire during construction.

1642, Pascal (1623- 1662, French mathematician) invented the manual computing machine.

1673, Leibnitz (G.W.Leibnitz, 1646- 1765438, a great German mathematician) built a mechanical computing machine that can perform four kinds of operations, which caused a sensation throughout Europe. His machine used shift addition in multiplication, which later evolved into binary and was also adopted by modern electronic computers.

1822, the British mathematician Charles Babbage (1791-1871) designed a model of the difference machine, which can perform arithmetic operations. It has a six-digit calculation ability, and more importantly, it can calculate any function of the second degree.

1854, GeorgeScheutz and his son Edward, who studied mechanical engineering, built the world's first fully operational differential extension.

1884, American engineer Herman Hollerith (1860-1929) made the first electronic computer. 1890, he used electromagnetic relay instead of some mechanical components to control punched cards, which was the first electromechanical automatic computer for human beings.

1937, Konradzuse (1910-1995) built the Z- 1 electromechanical computer. 194111.5, Z-3 was successfully developed. It is an electromechanical computer completely controlled by programs, all using relays, and all materials cost 25,000 marks (at that time, it was 6,500 dollars).

April 1939,1October 8 1940. This machine named plesNumberCalculator is like an advanced desktop calculator.

1944 in may, Howard aken, a professor of applied mathematics at Harvard university, built the "Harvard IBM automatic sequence control computer", which was later called "mark 1", and its components were relays.

1942, a machine model designed by VincentAtanasoff, a professor of mathematics at Iowa State College, and his student Bailey was born. It has 300 electron tubes, which can be added and subtracted, and uses drum capacitors to store 300 numbers. This is the first digital computer with regenerative storage function with electronic tubes as components in history. Later, the model they designed was named after them, called "Artner Sof-Berry Computer" (Atanasoff-Berry Puter), or ABC for short. ABC on the threshold of the digital age is indeed symbolic.

The birth of the first electronic computer;

On February 1946 and 10, the US Army Military Machinery Department and Moore College held a press conference to announce the successful development of the first electronic computer "Eniac". It has five functions: 1, 5000 addition operations per second; 2, 50 times per second multiplication operation; 3. Square sum cubic calculation; 4. Numerical operation of sine and cosine functions; 5. Other more complicated calculations. On February 15, a grand celebration was held in the Houston hall of the school. Dr. F. Juwett, President of the National Academy of Sciences of the United States, announced "Eniac". Then we went to Moore College to visit the magical "electronic head".

The "Ionak" that appears in front of people is not a machine, but ......

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 was John Atanasoff, an American professor.

According to most books, john von neumann (1903- 1957), an American Hungarian scientist, is the inventor of the electronic computer, and he has always been called "the father of the electronic computer". However, von Neumann himself does not consider himself "the father of electronic computers". Frankl, an American physicist who worked as von Neumann's assistant in Los Alamos Laboratory, wrote in his letter: "Many people recommend von Neumann as the' father of computers', but I am sure that he himself will never contribute to this mistake. 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, the basic function of von Neumann is to let the world know the basic concepts introduced by Turing. " It was von Neumann who personally put the title of "Father of Computers" on the head of British scientist alan turing (19 12- 1954). However, the real "father of computers" is neither von Neumann nor alan 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 V. atanasoff of the United States (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 invented the electronic computer with the help of his graduate student 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 leave, two improved ABC computers can be executed. 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 storage parts. 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 a Bulgarian national and won the highest scientific prize in Bulgaria. ......

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 the computer in the present sense, but a copy of the American national defense network. The computer is not strong, but the Internet is strong. The first personal computer was produced by ibm in the United States, and the computer came into being. Of course, computers can't. The most important thing to make a computer run is the operating system. Since ibm began to cooperate with Bill Gates, more than 99% users around the world have used Microsoft's system. Today's computers are a combination of hardware+software+Internet, and one of them is waste.

Remember to adopt

How was the computer invented?

The world's first electronic computer was born in 1946 at the Smithsonian Museum in Washington, USA. Her name is "Enik".

The first computer in the world was invented in World War II. Because it is used to draw ballistic maps for the US Navy. It is half the size of a football field and contains 500 miles of wires. It uses electromagnetic signals to move mechanical parts. Its execution speed is very slow, every 3-5 seconds, and its adaptability is poor, so it is only suitable for special fields. He is just a general-purpose computer.

In just a few decades, computers have miraculously multiplied for four generations. The first generation is a computer that uses vacuum tubes to execute. Eleven years later, the second generation transistor calculator appeared. Seven years later, the third generation integrated circuit computer was updated. Ten years later, a large-scale integrated circuit computer was invented. In the past few decades, computers have made such great progress, each time more advanced and more widely used. Thus becoming the darling of modern society.
