Who invented the first computer? As the title suggests, thank you

The world's first truly electronic digital computer was actually developed in 1935 and 1939 by John Vincent Atanasoff, an associate professor in the Department of Physics at Iowa State University, and his collaborator Clifford Berry 6 1 Berry (then a graduate student in the Department of Physics), using 300 electron tubes. It was named ABC (Atanasoff-Berry Computer). However, this machine is only a prototype, and it does not fully realize Athanasov's vision. In 1942, the outbreak of the Pacific War, Athanasov was drafted into the army, and the development of the ABC was interrupted.

However, the logic structure of the ABC computer and the novel design ideas of the electronic circuit provided great inspiration for the development of the electronic computer. Therefore, Atanasov should be recognized as the "father of electronic digital computers". ENIAC (Electronic Numerical Integrator and Computer) has always been mistaken for the world's first real electronic computer, and domestic textbooks have always expressed it in this way.

ENIAC began manufacturing in 1943 and was completed in February 1946, but its design idea was basically the same as that of ABC, but it used more tubes and more computing power, mainly used to calculate ballistics and develop hydrogen bombs. Its head is John W. MowleyMauchly) and Eckert, J

presper eckert）。As soon as they finished manufacturing ENIAC, they applied for a U.S. patent. It was this patent that led to the long-running dispute between ABC and ENIAC over "the world's first electronic computer".

In 1973, the U.S. District Court for the District of Minnesota issued a formal verdict overturning and revoking Moakley's patent, legally determining that Atanasov was the real inventor of the modern computer. Although Mokley lost his patent, their credit cannot be erased, after all, it was they who completely built the electronic digital computer in the true sense of the word according to Atanasov's ideas.

The first computer (ENIAC) was born in the United States in February 1946. The American mathematician von Neumann, who proposed the program storage, began the development of ENIAC in 1943 with the funding of the U.S. War Department, which was completed in 1946;

The person who invented the CPU was the United States, and the person who invented the mobile phone was also the United States, and without the United States, China is a chicken rib.

The earliest electronic computers were far different from today's powerful desktops. They weigh several tons, but they can only store a small number of numbers and letters. One of the first computers of this kind was developed in the United States by a group of scientists led by John Mochley and John Eckert.

They built the computer in 1942 and 1946 and named it "ENIAC".

The extremely small storage capacity of the ENIAC means that it is difficult to use. It is also very unreliable because it has about 10,000 tubes. These tubes overheat easily and often need to be replaced.

But that was the beginning. ENIAC can calculate the sum of two numbers in milliseconds, which means that it can do the same calculations in one day as it takes a human mathematician one year to do.

Later developments in computers began by making them easier to use: they stored a "program", or a series of instructions that told the computer what to do; found a way to increase the amount of computer storage; The addition of instruments such as keyboards makes it easier to enter the required data.

Perhaps the rapid development of computers is inseparable from the invention of the transistor in 1947. This invention provides a smaller alternative to the tube, which is something that doesn't get hot.

Soon, computers became smaller and more reliable. The modern "information age" has really begun!

In the 19th century, the British inventor Charles Babbage was assisted by Edda, the Countess of Lovelace (also known as Edda Augusta), to design a huge mechanical "computing engine". It's full of levers and cogs.

Some people see this machine as the first computer.

On February 14, 1946, the world's first computer was born at the Moore Electrical College of the University of Pennsylvania in the United States.

Almost all computer textbooks in China indicate that the world's first electronic computer was born in 1946, its name is "ENIAC (Eniac)", and the developer is John Mokry

mauchly) and Eckert.

But recently, this classic conclusion, which has always been widely enclosed, has been the subject of a huge controversy, and there has been an unprecedented heated debate around the topic of "who is the real 'father of computers'". In order to find the true "father of the computer", it is necessary to redefine the first computer, which has the potential to shake or even subvert the long-standing impression ...... in the minds of the Chinese people

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 major advance in human technology.

And we usually call this kind of computer that uses a vacuum tube the first generation of computers.

On February 14, 1946, the world's first computer, ENIAC, was born at the University of Pennsylvania in the United States. Dr. Mauchly and his student Eckert designed.

Originally invented by Johann von Neumann.
