It was the people of which country who first invented the computer

First: In 1940, Walter Aiken in the United States built the first new type of computer, named "Mark 1". The computer was huge, made loud noises when operated, and could only handle two additional problems per second, but it was the first computer after all.

The second type: February 1946 at Moore College of Pennsylvania State University in the United States was invented by a research group led by Professor Mochley and his doctoral student 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 the predecessors, there is no invention of the computer!!

Most people think of the "world's first electronic digital computer" as "ENIAC", which was introduced in 1946 and was mainly used to calculate ballistics. It is manufactured by the Moore Institute of Electrical Engineering of the University of Pennsylvania in the United States, but it is bulky, covering an area of more than 170 square meters, weighing about 30 tons, and consuming nearly 140 kilowatts of electricity. Obviously, such a computer costs a lot and is inconvenient to use.

In fact, in 1973, according to the ruling of the U.S. Supreme Court, the earliest electronic digital computer should have been John Atanasov, an associate professor of physics at the University of Iowa, and his graduate assistant Clifford EBerry, 1818-1963) was manufactured in October 1939.

Moakley (and Eckert (.)

The world's first general-purpose computer, "ENIAC", was born at the University of Pennsylvania in the United States on February 14, 1946. The inventors were the American Moakley (and Eckert (.

The US Department of Defense uses it for ballistic calculations. It was a behemoth with 18,000 tubes, covering an area of 150 square meters, weighing 30 tons, consuming about 150 kilowatts of electricity and performing 5,000 operations per second, which seemed insignificant now, but was unprecedented at the time. ENIAC uses electron tubes as components, so it is also known as tube computers, which is the first generation of computers.

Tube computers cannot work for too long because of the large volume of the tubes used, the power consumption is large, and they are easy to generate heat.

Significance

Since the birth of the first generation of computers, computer technology and industry have been in a stage of rapid development. Computer science has become a fast-growing, permeable, and far-reaching discipline, and the computer industry has developed into an industry of strategic significance around the world. The degree of development of computer science and the computer industry has become an important indicator to measure the strength of a country's comprehensive national strength.

ENIAC, the world's first electronic computer, covers an area of 170 square meters, weighs 30 tons, consumes about 150 kilowatts per hour, and can perform 5,000 operations per second. Used by the US Department of Defense for ballistic calculations.

The earliest electronic computers were far different from today's powerful desktops. They weigh several tons, but they can only store a small number of numbers and letters. One of the first computers of this kind was developed in the United States by a group of scientists led by John Mochley and John Eckert.

They built the computer in 1942 and named it "ENIAC" (i.e. Electronic Numerical Integrator) The extremely small amount of storage for ENIAC meant it was difficult to use. It is also very unreliable because it has about 10,000 tubes. These tubes overheat easily and often need to be replaced.

But that was the beginning. ENIAC can calculate the sum of two numbers in milliseconds, which means that it can do the same calculations in one day as it takes a human mathematician one year to do. Later developments in computers started by making them more convenient to use

A "program", or a series of instructions that tell the computer what to do, is stored; found a way to increase the amount of computer storage; The addition of instruments such as keyboards makes it easier to enter the required data. Perhaps the rapid development of computers is inseparable from the invention of the transistor in 1947. This invention provides a smaller alternative to the tube, which is something that doesn't get hot.

Soon, computers became smaller and more reliable. The modern "information age" has really begun! Attached:

In the 19th century, the British inventor Charles Babbage was assisted by Edda, the Countess of Lovelace (also known as Edda Augusta), to design a huge mechanical "computing engine". It's full of levers and cogs. Some people see this machine as the first computer.

My computer is also up and running. My computer is also an alternative computer mode. Just need avant-garde support. Actually, it's okay not to. I just don't do computers
