What is the difference between the world s first computer and today s desktop computers?

Entry. The first electronic computer was called ENIAC (electronic numerical integrator and computer), which was born in the United States on February 14, 1946. The "Moore Group" that undertook the development task consisted of four scientists and engineers Eckert, Mokley, Goldstein, and Box, and the chief engineer Eckert was only 24 years old at the time.

Inauguration of Moore College of Electrical Engineering, University of Pennsylvania, USA. It is the world's first modern electronic computer, "Eniac". This behemoth covers an area of 170 square meters and weighs 30 tons.

At the unveiling ceremony, "Eniac" performed its "trick" for the guests - 5,000 additions and 500 multiplications in 1 second, which was more than 1,000 times faster than the fastest relay computer at the time. This perfect appearance made the guests applaud.

ENIAC: 1 meter long, 1 meter wide, covers an area of 170 square meters, 30 consoles, about the size of 10 ordinary rooms, weighs 30 tons, consumes 150 kilowatts of electricity, and costs 480,000 US dollars. 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 performs 5,000 additions or 400 multiplications per second, which is 1,000 times that of a relay computer and 200,000 times that of manual calculations.

The first computer was introduced in 1946 and was named "ENIAC".

The first computer of modern times was invented in 1946 and was named "ENIAC".

But in fact, the first computer was in 1642, when the 19-year-old French mathematician, physicist, and philosopher Blaise Pascal (1623 1662, yes, the unit of pressure in the eighth-grade physics textbook) invented a mechanical computer that could automatically carry and perform four operations: addition, subtraction, multiplication, and division.

The first computer in the world was ENIAC.

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

It has been nearly 60 years since the birth of the first computer, during which time computers have developed at an astonishing rate, first with the replacement of electron tubes by transistors, and then by the development of microelectronics, which has made the components on computer processors and memory smaller and more numerous, and the computing speed and storage capacity of computers have increased rapidly.

How the world's first computer worked:

When the computer is running, according to the predetermined arrangement, the first instruction is taken out from the memory, and through the decoding of the controller, the data is taken out from the memory for specified operations and logical operations according to the requirements of the instruction, and then the result is sent to the memory according to the address.

Next, take out the second command and complete the specified operation under the command of the controller. Continue in sequence until you encounter a stop command. <>

Computers, also known as electronic computers, are tools that we often use in our daily life and work. It has a wide range of uses: medical, architectural, teaching, military, etc., as long as people can see it.

The continuous development of modernization is inseparable from the use of computers, and it is really difficult for modern human beings to imagine what the world would be like without computers, but how was the computer invented? Today, let's witness the birth of the world's first computer.

01 The world's first general-purpose computer, "ENIAC", was born at the University of Pennsylvania in the United States on February 14, 1946. The inventors were the Americans Moakley and Eckert.

02 It is used by the U.S. Department of Defense for ballistic calculations. It was a behemoth with 18,000 tubes, covering an area of 150 square meters, weighing 30 tons, consuming about 150 kilowatts of electricity and performing 5,000 operations per second, which seemed insignificant now, but was unprecedented at the time.

03 ENIAC uses electron tubes as components, so it is also called tube computers, which is the first generation of computers.

04 Due to the large volume of the tube used in the tube, the power consumption is large, and it is easy to generate heat, so the working time should not be too long.

05 People began to study the use of electron tubes as a"Electronic switches"to improve the computing speed of the computer. Many scientists took part in experiments and research, and finally made the world's first electronic computer, which was named"Eniake"。

After introducing the world's first computer, do you feel that it is not easy?
