In which country the first computer was invented

Developed by the University of Pennsylvania, USA.

You know where the world's first computer was located and who invented it.

In 1956, Xia Peisu completed the design of the first electronic computer combinator and controller, and at the same time compiled the first lecture notes on the principles of electronic computers in China.

In 1957, Harbin Institute of Technology successfully developed China's first analog electronic computer.

In 1958, China's first computer, the 103 general-purpose digital electronic computer, was successfully developed, running at a speed of 1,500 times per second.

In 1959, China successfully developed the 104 electronic computer, with a computing speed of 10,000 times per second.

In 1960, China's first large-scale general-purpose electronic computer, the 107 general-purpose electronic digital computer, was successfully developed.

In 1963, China's first large-scale transistor electronic computer, the 109 machine, was successfully developed.

In 1964, the 441B all-transistor computer was successfully developed.

In 1965, China's first million-times integrated circuit computer"djs－ⅱ"The type of operating system is completed.

In 1967, a new transistor large-scale general-purpose digital computer was born.

Japan. Toshiba's T1000, this product launched in 1985 features an Intel 8086 CPU, 512KB of RAM, and a 9-inch monochrome display without a hard disk to run the MS-DOS operating system.

The first real computer was born in the United States in 1946.

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 operations 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 the future, the real electric calculator had to wait until 1944 AD 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 major advance in human technology.

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

Who invented the computer? See what you'll know.

The first electron.

Computers came in the second life.

Since the realm of the war soon after the bai made, that du

With the development of artillery, the trajectory calculation is becoming more and more complex, and some of the original computers can no longer meet the requirements of use, and there is an urgent need for a new fast calculation tool. In this way, with the efforts of some scientists and engineers, electronic computers came into being on the basis that electronic technology had shown to have functions such as counting, calculation, transmission, and storage control at that time. The world's first electronic computer was named"Eniake"It was successfully developed by Eckert and others at the University of Pennsylvania in the United States in 1946.

It was equipped with more than 18,000 electron tubes and a large number of resistors and capacitors, and for the first time it was calculated with electronic circuits. "Eniake"You can do 5,000 additions per second, or 400 multiplications. If you used the fastest electromechanical computer at that time to do a 40-point ballistic calculation, it would take two hours, and"Eniake"It only took 3 seconds, which was a remarkable feat at the time.

Yet"Eniake"It's not perfect, in fact it doesn't have memory, only registers made of tubes, and it can only store 10 digits. When it was necessary to convert to another problem, it was necessary to re-solder the wires, which was very time-consuming.

The computer is American, von. Neumann, invented in 1946.

Generally speaking.

The world's first power-powered sub-digital computer" is considered by most to be the "ENIAC" introduced in 1946, which was mainly used to calculate ballistics. It is manufactured by the Moore Institute of Electrical Engineering of the University of Pennsylvania in the United States, but it is huge, covering an area of more than 170 square meters, weighing about 30 tons, and consuming nearly 150 kilowatts of electricity. Obviously, such a computer costs a lot and is inconvenient to use.

In fact, in 1973, according to the U.S. Supreme Court's ruling, the earliest electronic digital computers should have been John Atanasov, an associate professor of physics at Iowa State University, and his graduate assistant, Clifford EBerry, 1918-1963) made in October 1939 by "ABC" (Atanasoff-Berry-Computer).

The first computer was called ENIAC (the abbreviation of electronic numerical integrator and computer) in English, which was 30 meters long and weighed three times

Ten tons, on February 15, 1946.

DAO America was born.
