ENIAC the first electronic computer was developed by Prof.J.Presper Eckert and John Mauchly from Moore school of Engineering. ENIAC was mainly designed for U.S army during the World War II.
ENIAC had 18,000 vacuum tubes , nearly 70,000 resistors, 10,000 capacitors and 60,000 switches. The weight of ENIAC was 27 tons and it occupied 5,000 square feet space. The speed at which it could perform computation was 300 multiplications per second.
ENIAC was considered as a significant development in the filed of computers mainly because of the increased speed at which it could perform computations.
