NIAC is an acronym for "Electronic Numerical Integrator and Computer," built at the University of Pennsylvania's Moore School of Electrical Engineering.As a general-purpose computer to solve a wide range of calculations,this distinguished the ENIAC from earlier automated calculating machines designed for single problem-solving applications.They began the ENIAC in 1943 and completed the ENIAC in 1946.
The ENIAC was introduced to the public on Valentine's day,14 February 1946
The ENIAC's technical specifications :
took up 3,000 cubic feet
- weighted 30 tons
- used 18,000 vacuum tubes and 70,000 registers
- required more than 170 kilowatts of power
- had a random access memory capacity of about 1,000 information bits
- used punched cards to store data
The ENIAC was used by the U.S. Army for military calculations in the World War II.
