Who invented the computer HEH

Inventor Johann von Neumann.

Computer (computer), commonly known as computer, is an electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed. A computer that consists of a hardware system and a software system without any software installed is called bare metal.

It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

Inventor of the computer John von Neumann. 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 application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society.

In the early days, the PC machine was called a microcomputer, and it was called a computer among Hong Kong businessmen in the early days, and later it was introduced into China and became the most familiar name to the public. The scientific name of the computer is the electronic computer, which was developed from the early electric calculator. In 1946, the world's first electronic digital computer "ENIAC" appeared for calculating ballistics.

It is manufactured by the Moore Institute of Electrical Engineering of the University of Pennsylvania in the United States, but it is huge, covering an area of more than 170 square meters, weighing about 30 tons, and consuming nearly 100 kilowatts of electricity. Obviously, such a computer costs a lot and is inconvenient to use. In 1956, the transistor electronic computer was born, which was the second generation of electronic computers.

It can be accommodated in just a few larger cabinets, and the calculation speed is greatly improved. In 1959, the third generation of integrated circuit computers appeared. The original computer was invented by Johann von Neumann (at that time the computing power of the computer was equivalent to today's calculator), the size of three warehouses, and gradually developed.

It was the American mathematician von Neumann.

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

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 major advance in human technology.

And we usually call this kind of computer that uses a vacuum tube the first generation of computers.

The world's first computer was invented in 1946 by Americans Mao Qilei and Eckert.

In 1946, the world's first electronic digital computer "ENIAC" appeared for calculating ballistics, which was manufactured by the American Mao Qilei and Eckert of the Moore School of Electrical Engineering at the University of Pennsylvania. ENIAC is huge, covering an area of more than 170 square meters, weighing about 30 tons and consuming nearly 150 kilowatts of electricity. Obviously, such a computer costs a lot and is inconvenient to use.

An electronic computer, commonly known as a computer, is an electronic computing tool. In Chinese mainland, computers are also often used to refer to electronic computers. At present, an electronic computer is a device that processes information according to a pre-set program.

Electronic computers are divided into supercomputers (also known as "supercomputers"), large-scale computers, medium-sized computers, small computers, and microcomputers (referred to as "microcomputers", including personal computers, PCs), which have gradually entered all fields of society, especially into the family and personal fields, and have greatly changed the daily appearance of society.

From the mid-1930s to the late 1940s, many people were developing modern, digital, electronic, general-purpose electronic computers. Many experimental machines have been built and may have been Turing-complete. These machines were all billed as the first electronic computers at the time, but they had limited ability to deal with general-purpose problems, so their designs were eventually abandoned.

The computer was invented in 1946. Around 1940-1942, in the process of developing missiles, there was an urgent need for a tool that could quickly calculate in order to control the flight of missiles. When it deviates from the orbit of the human being, pull it back into orbit.

This results in an electronic computer that calculates the deviation of the missile's trajectory from the predetermined trajectory in a period of 1,100 or 1,100 seconds. Electronic computers do not calculate in the decimal system, but in binary systems. Its appearance is one of the largest contemporary inventions in the world.

The inventor of the first computer was a mathematician named von Noemen.

The first computer (ENIAC) was born in the United States in February 1946. The American mathematician von Neumann, who proposed the program storage, began the development of ENIAC in 1943 with the funding of the U.S. War Department, which was completed in 1946;

War needs. During World War II, the United States needed to calculate calculus for a new type of manufacturing, and traditional calculation tools could not meet the needs, so they wanted to invent a tool for complex calculations. The first computer was called eniac (Chinese name:

Eniac), which is an electronic digital integral computer. Later it was also used in the manufacture of the atomic bomb. In short, it was the war that gave birth to computers.
