What country did the computer invent? When is it?

Who invented the computer is strictly difficult to define. 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 great progress 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.

Computers were invented in the United States.

The computer was invented by the United States.

In the mid-40s of the 20th century, the Department of Electrical Engineering of the University of Pennsylvania, led by Molic and Eckert, developed an electronic numerical integration and computer for the calculation of the ballistic trajectory of artillery shells for the Aberdeen Ballistic Research Laboratory of the U.S. Army Ordnance Department.

Eniaq's computer covers an area of 170 square meters, with a total weight of 30 tons, using 18,000 tubes, 6,000 switches, 7,000 resistors, 10,000 capacitors, 500,000 wires, 140 kilowatts of power, and 5,000 additions per second.

Unveiled in the United States on February 15, 1946, the computer marked the beginning of the computer age.

The role of the computer:

2. Using the commonly used office software on the computer, you can count all kinds of documents on the computer.

3. Use the computer to play a variety of games, so that people can relax in their spare time.

5. Drawing with a computer can not only create as you like, but also change the color conveniently.

7. The computer is connected to the Internet, and you can get all kinds of information from all over the world while sitting at home, and you can also quickly transmit the information to all parts of the world by e-mail. <>

The inventor of the computer, John von Neumann, came from the United States.

The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research and application to all fields of society, and has formed a huge computer industry, which has moved the technological progress of the whole world, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises and institutions, and entered the homes of ordinary people, becoming an indispensable tool in the information society.
