1, abbreviated as ENIAC in English, is called electronic numerical integrator and calculator (ENIAC for short). Born in the University of Pennsylvania, USA! ?

2. The inventors were American Moakley and J.PresperEckert, and the US Department of Defense used it for ballistic calculation. It is a giant, with 18000 electron tubes, an area of 170 square meters, weighing 30 tons, consuming about 150 kilowatts of electricity, and performing 5000 operations per second, which is insignificant now, but unprecedented at that time.

ENIAC uses electron tubes as components, so it is also called electron tube computer, which is the first generation computer. Electron tube computers are bulky, consume high power, are prone to heat, and cannot work for long.

With the birth of the first generation of computers, computer technology and industry have been in a high-speed development stage. Computer science has become a subject with rapid development, strong penetration and far-reaching influence, and the computer industry has developed into a world strategic industry. The development degree of computer science and computer industry has become an important symbol to measure a country's comprehensive national strength.
