ENIAC - World's first general purpose computer. It was very important and great invention at that time. ENIAC stands for 'Electronic Numerical Integrator and Computer.'
ENIAC was designed and built for the US army to calculate artillery firing tables. It began as a secret World War II military project carried out by John Mauchly and John Presper Eckert Jr. But ENIAC, also called 'The Giant Brain', was not completed until after the war.
When ENIAC was introduced to the public in 1946, it wa shailed as an incredible breakthrough that could compute mathematical problems with breathtaking speed.
The Machine's power and general purpose uses fired the imagination of the world. ENIAC weighed 30 tonnes.
The fact that today a single microchip, no bigger than a fingernail, can do more than those 30 tonnes of hardware does not take away from the senses of awe that ENIAC inspired at that time.
They created their own flow charts, programming sheets, wrote the program and placed it on the ENIAC using a challenging physical interface, which had hundreds of wires and 3,000 switches. ... In a special ceremony, the Army introduced ENIACand its hardware inventors Dr. John Mauchly and J. Presper Eckert.
