In 1946 people had the first electronic computer

In 1946, the first computer was called ENIAC, which was the world's first general-purpose computer and the second electronic computer after ABC. The ENIAC was a Turing-complete electronic computer capable of being reprogrammed to solve a variety of computational problems. It was proclaimed in the United States on February 14, 1946.

The ENIAC was a Turing-complete electronic computer capable of being reprogrammed to solve a variety of computational problems. It was proclaimed in the United States on February 14, 1946. The Moore group responsible for the development task consisted of four scientists and engineers: Eckert, Mokley, Zhu Chuanyu, Goldstein, and Box.

Measuring meters long, 6 meters wide and meters high, the ENIAC covers an area of about 170 square meters, has 30 operating stations, weighs 30 tons and consumes 150 kilowatts of electricity.

It contains 17,468 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 capacitors, 1,500 relays, more than 6,000 switches, and the calculation speed is 5,000 additions or 400 multiplications per second, which is 1,000 times faster than electromechanical computers running with relays and 200,000 times faster than manual calculations.

The world's first computer was born in 1946, and its name was ENIAC, which stands for Electronic Numerical Integrator and ComputerElectronic digital integration computer

ENIAC is a complete electronic computer of Turing.

It can be reprogrammed to solve all kinds of computing problems. It was proclaimed on February 14, 1946 in the United States. The Moore group responsible for the development task consisted of four scientists and engineers: Eckert, Mokley, Zhu Chuanyu, Goldstein, and Box.

Introduction:

The eniac is capable of 5,000 additions per second (it is estimated that the fastest addition is only 5 additions per second) and 400 multiplications per second. It can also perform squares and cubes, and calculate trigonometric functions such as sine and cosine.

and some other more complex operations.

This was a remarkable achievement at the time! A trajectory that used to take more than 20 minutes to calculate now only takes 30 seconds! This alleviated the problem of the extremely serious calculation speed at that time lagging far behind the actual requirements.

Because at that time von Neumann was involved in the atomic bomb.

He joined the computer development work with a large number of computational problems encountered in the development of the atomic bomb. Therefore, it can be said that ENIAC also contributed to the creation of the world's first atomic bomb.

The ENIAC is a fully electronic computer capable of being reprogrammed to solve a variety of computational problems. It was proclaimed in the United States on February 14, 1946. The person who undertook the development task was the scientist Johann von Neumann.

It is composed of engineers Eckert, Mockley, and Goldstein of the "Moore Group" and Chinese scientist Zhu Chuanyu. Chief engineer Eckert was only 25 years old at the time.

Features of electronic computers:

1. Fast operation speed

The computer is composed of internal circuits, which can complete various arithmetic operations at high speed and accurately. Today's computer systems.

The computing speed has reached trillions per second, and the microcomputer can also reach more than 100 million times per second, so that a large number of complex scientific computing problems can be solved. For example, calculations for satellite orbits, large dams, and 24-hour weather calculations take years or even decades, while computers can be completed in just a few minutes.

2. High calculation accuracy

The development of science and technology, especially cutting-edge science and technology, requires highly accurate calculations. The accuracy of a computer-controlled missile against a predetermined target is inseparable from the computer's precise calculations. The average computer can have a dozen or even dozens of bits (binary.

Significant figures, calculated with an accuracy of a few thousandths to a few millionths, are beyond the reach of any calculation tool.

3. Strong logical operation ability

Computers are not only capable of accurate calculations, but also have the function of logical operations, which can compare and judge information. The computer can save the data, programs, intermediate and final results of the calculations, and can automatically execute the next instruction according to the judgment results for the user to call at any time.

On February 14, the world's first electronic computer, also known as a general-purpose computer, was successfully developed by the Americans Mokley and Eckert after many years of research and discussion. Borrowing from the laboratories of the University of Pennsylvania and the scientific and technological experience of contemporary experts, this general-purpose computer was finally created.

The world's first electronic computer was the result of generations of work and numerous scientific experiments. But due to the level of technology, first of all, this computer is huge. It is understood that there are more than 18,000 photoelectron tubes inside, and the total area has reached 170.

It was similar in size to the larger houses of today, while its weight was up to 30 tons.

In 1946 the first computer was called the Atanasov-Berry computer.

The Atanasov-Berry computer was the world's first electronic computer.

Designed in 1937 by the American scientist Artanasov, it is not programmable and purely buried, designed only to solve systems of linear equations.

And in 1942 it was successfully tested. It is recognized as a pioneer in computers, laying a solid foundation for the development of today's mainframe and small computers.

Performance characteristics:First, electrical energy and electronic components were used, which at the time were electronic vacuum tubes.

Second, the two-liquid Qi carry system is adopted.

Instead of the usual decimal system.

Third, capacitors are used as memory.

Renewable and error-free.

Fourth, perform direct logical operations.

And not the usual numerical arithmetic.
