The computer was invented by computer scientists in the first half of the 20th century. The earliest computers were mechanical computers, also known as giant calculators, which first appeared in the late 19th and early 20th centuries. But true Electronic computers were developed during World War II, the most representative being the ENIAC (Electronic Numerical Integrator And Computer), which came out in 1945. ENIAC was the world's first real electronic computer, which not only created the history of computers, but also created the global electronic computer manufacturing industry. Since then, the electronic computer has been continuously improved and upgraded, and has become the wide range of computers we use today.
The earliest prototypes of computers date back to ancient calculators, but the origins of modern computers can be traced back to the 1940s. The first computer is believed to have been the ENIAC (Electronic Digital Integration Calculator) in 1946, a massive electronic computer used to perform scientific and engineering calculations. Since then, the development of computers has gone through multiple stages, including the invention and application of transistors, integrated circuits, and microprocessors. Over time, computers have become smaller and more powerful, becoming one of the indispensable tools in modern society.
On February 14, 1946, the world's first computer ENIAC was born at the University of Pennsylvania in the United States, named ENIAC(ENIAC).
