The world s first computer weighed about several times as much as the 14 inch laptops commonly used

The world's first modern electronic computer, Eniac, was born at the University of Pennsylvania in the United States on February 14, 1946, and was officially announced to the public the next day. At the inauguration of the Penn More Institute of Electrical Engineering, the behemoth covers an area of 170 square meters and weighs 30 tons. Generally, the weight of 14 inches is less.

And according to the calculation. 30 1000 times.

The world's first computer weighed about 30 tons; Nowadays, the commonly used 14-inch laptop generally weighs more than 2kg, which is 3kg

then 30,000 3 10,000, that is, by weight, the former is 10,000 times that of the latter.

The world's first computer called ENIAC weighed about 30 tons, and now the 14-inch laptop weighs about 1 8 kg and 2 2 kg, which is 13,600 17,000 times the current one.

The world's first modern electronic digital computer, ENIAC, was born at the University of Pennsylvania on February 14, 1946, and was officially announced to the public the next day.

The ENIAC is 30 48 meters long, 6 meters wide and 6 meters high.

It covers an area of about 170 square meters, has 30 operating stations, weighs 30 tons, consumes 150 kilowatts of electricity, and costs $480,000.

It contains 17,468 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 10,000 capacitors, 1,500 relays, and more than 6,000 switches.

The calculation speed is 5,000 additions or 400 multiplications per second, which is 1,000 times faster than electromechanical computers operated with relays and 200,000 times faster than manual calculations.

Weighing 30 tons The first electronic computer was called ENIAC ("Eniac", the abbreviation of electronic numerical integration computer, English full name is Electronic Numerical Integrator and Computer), which was born in the United States on February 15, 1946 at the University of Pennsylvania. Announced. ENIAC is 30 meters long and weighs 30 tons

It was built by the American von Neumann working group in order to calculate the range of artillery shells.

The world's first electronic computer "Eniake" February 14, 1946, at the Moore School of Electrical Engineering of the University of Pennsylvania in the United States, this behemoth covers an area of 170 square meters and weighs 30 tons.

The world's first electronic computer, called:

Eniac (formerly known as ENIAC, which was later translated as "Iliak" in Chinese) was invented in 1946 by the Americans Motorley and Eckatki. If you're taking a computer literacy test, there's nothing wrong with that;

But if you're telling someone about the history of computers, that's a mistake. Another version holds that the inventors of the world's first electronic computer were not Americans, but British. What exactly the "world's first computer" built by Atanasov looked like, because no information was disclosed.

material, most people can't know; No one can speculate what the "world's first electronic computer" invented by the unsung hero of Britain will look like. The "world's first computer", built by Motorley and Eckateki in 1946, is available. That's a real "giant machine" :

The machine shares 18,000 electron tubes, consumes 150 kilowatt-hours of electricity, covers an area of 167 square meters, and is as tall as a three-story building, but the speed of operations is only 5,000 times per second. Moreover, the input calculation program is very complicated, and the long and numerous punch cards can make the expert's head hurt. When something goes wrong, the experts run from downstairs to upstairs and upstairs again.

Downstairs, I was busy sweating, and it was difficult to diagnose the problem.

The time was also at the end of the 30s of the 20th century.

It covers an area of 167 square meters.

No one seems to have weighed it.

25.It turns out that the world's first computer looks like this! It weighs 50 tons and covers an area of 170 square meters. mp4

30 tons. On February 14, 1946, the world's first electronic digital computer, ENIAC, was born at the University of Pennsylvania in the United States. The computer consisted of 17,468 tubes, 60,000 resistors, 10,000 capacitors, and 6,000 switches, consuming 140 kilowatts of power and costing $450,000.

Its total volume is about 90 cubic meters, weighs 30 tons, covers an area of 170 square meters, and needs to be stored in a large room more than 30 meters long.

Nowadays, computers are getting thinner and lighter, and you don't have to look at other data, just look at the weight, and you will really feel the rapid development of modern technology. But do you know the weight of the first computer?

On February 14, 1946, the world's first electronic digital computer, ENIAC, was born at the University of Pennsylvania in the United States. The computer consisted of 17,468 tubes, 60,000 resistors, 10,000 capacitors, and 6,000 switches, consuming 140 kilowatts of power and costing $450,000. Its total volume is about 90 cubic meters, weighs 30 tons, covers an area of 170 square meters, and needs to be stored in a large room more than 30 meters long.

The computer can do 5,000 additions per second, or 400 times multiplication, which is 1,000 times faster than a mechanical relay computer. It is capable of completing tens of millions of multiplications in a single day, which is roughly equivalent to the work of a person operating on a desktop computer for 40 years. However, sometimes several or dozens of calculations take hours or 1-2 days to prepare for the line connection, which is one of its fatal heels.

Another weakness is that the storage capacity is too small, at most 20 10-digit decimal numbers. General Mountbatten of the Institution of Radio Engineers in Great Britain hailed Eniac's birth as the birth of an electronic brain, and the name of the computer spread. On February 15, 1946, the fully automatic computer ENIAC (i.e. Electronic Mathematical Integration Computer) was officially delivered, and it was in service for nine years until October 1955, when the power was finally cut off.

The weight of the world's first computer was about 30 tons, and the 14-inch laptop that is commonly used now weighs more than 2kg, so the former is more than 10,000 times that of the latter, but the exact number cannot be had, because the "commonly used 14-inch laptop" you said is not specific, the weight is an approximate number. 10,000 times to 15,000 times or so.
