China s most advanced computer is made of technology

In 1946, the Department of Electrical Engineering at the University of Pennsylvania, led by Molitch and Eckert, developed an "electronicnumericalintegratorandcalculator" for the U.S. Army Ordnance Department's Aberdeen Ballistic Research Laboratory for the calculation of the trajectory of artillery shells. The computer, called "Eniac", covers an area of 170 square meters, weighs 30 tons, uses 18,000 tubes, 6,000 switches, 7,000 resistors, 10,000 capacitors, 500,000 wires, consumes 140 kilowatts, and can perform 5,000 addition-seconds calculations. This behemoth was unveiled in the United States on February 15, 1946.

The advent of this computer marked the beginning of the computer age.

Who invented the computer is strictly difficult to define. The original meaning of the computer was "calculator", which means that humans invented computers to help them do 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. This computer uses vacuum tubes to process Jingxiang signals, so it is bulky (it takes up a room) and consumes a lot of electricity (everyone in the 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.

The first generation of computers was the size of two classrooms, which was much different from the size of the personal computers we use today. At that time, the computer parts were vacuum tubes (which can no longer be found) and the archive thing is a punch card, if there is no design concept of predecessors, there is no invention of the computer, so it is a bit difficult to define who invented the computer.

China's most cutting-edge section of Huaiduan's science and technology, in addition to the Shandong ship holding the world's friends aircraft carrier, can say that the last two names are your "cow".
