Explain the factors which resulted in the inventions of ENIAC and Integrated Circuit.
Answers
Answer:
ENIAC (/ˈɛniæk/; Electronic Numerical Integrator and Computer)[1][2] was the first electronic general-purpose digital computer.[3] It was Turing-complete, and able to solve "a large class of numerical problems" through reprogramming.[4][5]

Although ENIAC was designed and primarily used to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory (which later became a part of the Army Research Laboratory),[6][7] its first program was a study of the feasibility of the thermonuclear weapon.[8][9]
ENIAC was completed in 1945 and first put to work for practical purposes on December 10, 1945.[10]
ENIAC was formally dedicated at the University of Pennsylvania on February 15, 1946 and was heralded as a "Giant Brain" by the press.[11] It had a speed on the order of one thousand times faster than that of electro-mechanical machines; this computational power, coupled with general-purpose programmability, excited scientists and industrialists alike. The combination of speed and programmability allowed for thousands more calculations for problems, as ENIAC calculated a trajectory in 30 seconds that took a human 20 hours (allowing one ENIAC hour to displace 2,400 human hours).[12] The completed machine was announced to the public the evening of February 14, 1946 and formally dedicated the next day at the University of Pennsylvania, having cost almost $500,000 (approximately $7,150,000 in 2020 dollars; inflation-adjusted). It was formally accepted by the U.S. Army Ordnance Corps in July 1946. ENIAC was shut down on November 9, 1946 for a refurbishment and a memory upgrade, and was transferred to Aberdeen Proving Ground, Maryland in 1947. There, on July 29, 1947, it was turned on and was in continuous operation until 11:45 p.m. on October 2, 1955.

The factors which resulted in the inventions of ENIAC and Integrated Circuit are as follows:
- An integrated circuit (IC) serves as a single device that is capable of carrying out complex digital calculations, as in the case of microprocessors, as well as high-level tasks like amplification and signal processing. There aren't many electronic circuits that don't use an IC, chip, or microchip.
- The computational power of ENIAC, combined with general-purpose programmability, excited scientists and industrialists alike. It was on the order of a thousand times faster than electro-mechanical machines. ENIAC calculated a trajectory in 30 seconds that would have taken a human 20 hours to calculate because of its speed and programmability, which enabled thousands more calculations to be made for problems.
