What's the story of inventing the computer?

The scientific name of computer is electronic computer, which is developed from the early electronic calculator. \x0d\ usually speaking of "the first electronic digital computer recognized in the world", most people think that it is "ENIAC" which came out in 1946 and is mainly used for ballistic calculation. It is manufactured by Moore Institute of Electrical Engineering, University of Pennsylvania, USA, but it is huge, covering an area of 170 square meters, weighing about 30 tons, and consumes nearly 140 kilowatts of electricity. Obviously, such computers are expensive and inconvenient to use. This statement is widely used in basic computer textbooks. In fact, according to the ruling of the US Supreme Court 1973, the earliest electronic digital computers should be john atanasoff, an associate professor in the Department of Physics of He Hua University, and Clifford Berry, his graduate assistant (181963). The reason for this misunderstanding is that a man named Moakley in the "ENIAC" research group copied john atanasoff's research results at 194 1 and applied for a patent at 1946. For various reasons, this error was not reversed until 1973. (See "john atanasoff" in Baidu Encyclopedia for details. I hope everyone will remember ABC and john atanasoff, and I hope this mistake can be corrected in future textbooks). Later, in order to commend and commemorate john atanasoff's great contribution in the computer field, former US President George W. Bush awarded john atanasoff the "National Science and Technology Award", the highest American science and technology award. \x0d\ 1956, the transistor electronic computer was born, which is the second generation electronic computer. Only a few larger cabinets can be installed, and the operation speed is greatly improved. The third generation of integrated circuit computers appeared in 1959. \x0d\ The original computer was invented by john von neumann (at that time, the computing power of the computer was equivalent to that of the current calculator), which was as big as three warehouses, and then it gradually developed. \x0d\ This is the latest stage of computer development since 1970s. By 1976, "Cray" made of LSI and VLSI made the computer enter the fourth generation. With the invention of VLSI, electronic computers are constantly upgrading to miniaturization, miniaturization, low power consumption, intelligence and systematization. In 1990s, computers developed in the direction of "intelligence", producing computers similar to human brains, which can be used for thinking, learning, memory and network communication. \ x0d \ 2 1 century, computers have become more notebook, miniaturized and specialized, and the operation speed exceeds 1 10,000 times per second, which is not only simple to operate and low in price, but also can replace part of people's mental work and even expand people's intelligence in some aspects. Therefore, today's microcomputers are vividly called computers. \ x0d \ 1980 IBM introduced the world's first personal computer. IBM introduced a personal computer based on Intel x86 hardware architecture and Microsoft MS-DOS operating system, and formulated the PC/AT specification. After that, the development of the microprocessor introduced by Intel and the operating system introduced by Microsoft is almost equivalent to the development history of personal computers. Wintel architecture completely replaced IBM's dominant position in the field of personal computers.
