Who invented the computer?

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.

The first electronic computer in the true sense of the United States was called ENIAC (electronic numerical integrator and computer), which was born in the United States on February 15, 1946. This is recognized by the IT and information circles and the whole world. So the first computer came from the United States.

However, it is not very appropriate to say "creation", because not everything in the computer was invented by the United States itself, and some things were invented by other countries. So it would be more appropriate to say that "computers were invented in the United States." Time 2007-12-24 23:
