What is the world's first computer?Somebody does not kown the first computer who designed.Now let us introduce the world's first computer.
February 14, 1946, the world's first computer ENIAC (Electronic Numerical Integrator And Calculator) was born at the University of Pennsylvania . During World War II, the U.S. military asked the University of Pennsylvania Ph.D. Mauchly and his Students Eckert ot design to replace the vacuum tube relay "electronic" computer - ENIAC (Electronic Numerical Integrator and Calculator), Electronic Numerical Integrator and Total Calculator).
The purpose is used to calculate the shell trajectory. This machine uses 18,800 vacuum tubes, length 50 British Feet wide and 30 feet, covering 1,500 square feet, weighing 30 tons (about one half of the large classrooms, six large As the weight). It's fast calculation per second in the 5000 addition operation, working for nine years.
This first computer is designed by Mauchly and Eckert spented for 3 years.
