Historical moment
1946 On February 4th, ENIAC was born in the University of Pennsylvania, which became an important milestone in the history of computer development.
Electronic behemoth
ENIAC is an "electronic" behemoth, covering an area of 65,438+0,500 square feet and weighing 30 tons, which is equivalent to the size of a classroom and the weight of six elephants. It was born to calculate the trajectory of shells.
Amazing operating speed
ENIAC has 18800 vacuum tubes and 5000 addition operations per second. It has been running for 9 years. Although the loss of vacuum tube is high, there is no loss when it runs continuously for five days at a time, and the inventor has to celebrate.
Development of computer
ENIAC has been born for more than 50 years. Computers are developing at an alarming rate. Transistors have replaced electron tubes. Microelectronics technology makes processors and memories smaller and smaller, and the operation speed and storage capacity increase dramatically.
The beginning of the information age
ENIAC opened the information age for mankind and changed the world. Although it is not as advanced as the pocket calculator now, its influence will always be engraved in the history of computer development.
Commemorate this moment
1996 February 14, US Vice President Al Gore launched ENIAC again to commemorate this moment. The process of technological innovation has never stopped, and computer technology will continue to promote the development of human society.
