It was considered the prototype of the first general-purpose computer, but it was not fully realized due to technical and financial problems. ** II. The Birth and Initial Development of Electronic Computers (1945 - 1958)** 1. ** Electronic Numeric Integration Computer (ENIAC)** - In 1946, John Mochley and Presbo Eckart of the University of Pennsylvania developed the world's first electronic digital integral computer (ENIAC). It used about 18,000 vacuum tubes and 70,000 resistances, covered an area of 170 square meters, weighed 30 tons, and could perform about 5000 addition operations per second, marking the beginning of the electronic computer era. 2. ** Initial development and application ** - In 1949, the first stored-program computer, Edvacs, was born. It adopted the concept of "stored-program" proposed by van Neumman, which meant that programs and data were stored in the computer's memory, and the computer could automatically access instructions and execute them. This had a profound impact on the development of subsequent computers. ** 3. The Age of Transcendence Computer (1958 - 1964)** - With the advancement of science and technology, the transistors replaced vacuum tubes as the main components of computers. The advantage of the crystal was its small size, low power consumption, and long lifespan. Before ENIAC, humans had also developed mechatronics computers, such as the Harvard Mark I computer, which was manufactured and debugged in 1943 - 1944. It was a relay computer with both mechanical and electrical characteristics. It was the earliest prototype of modern computers. Before the invention of the computer, humans had also experienced the process of counting with their fingers and using tools such as stones and ropes to assist in counting. The development of these counting methods also provided a certain foundation for the invention of the computer. "A Short History of the Future: Legends of the Intelligent Era" was equally exciting.
