Although the video provided abundant information, I will only touch on the most imperative aspects. World War II was a time of rockets, atomic bombs, and ENIAC. ENIAC which stands for Electronic Numerical Integrator and Computer was created by John Presper Eckert and John Mauchly in 1946. ENIAC’s initial purpose was to calculate biolistic tables of guns for the war. Unfortunately, ENIAC presented with multiple problems. First, the computer was made of large numbers of vacuum tubes that constantly burnt out. Second, to properly use ENIAC, the user must be familiar with advanced mathematics. Last and most importantly, ENIAC…

    Computers In Military Applications Computers have given the modern military a degree of efficiency and effectiveness that has completely changed the way the military operates at sea, in the air, and on the ground. The fast computational abilities and the accuracy of digital computing enable the military to perform more quickly with less risk to themselves and with less cost to their government. Wars fought prior to the advent of digital computing could take years to complete and resulted in tremendous loss of property on both sides. Weapons of mass destruction used to be the fastest way to achieve the objective.
