ENIAC: The House-Sized Computer That Started the Digital Age

Before laptops, before personal computers, and long before smartphones, there was ENIAC. Built during World War II to calculate artillery firing tables for the U.S. Army, ENIAC became one of the world's first large-scale electronic computers and marked the beginning of the digital age. Containing nearly 18,000 vacuum tubes, 70,000 resistors, and thousands of switches, the machine occupied approximately 1,800 square feet, weighed around 30 tons, and consumed enormous amounts of electricity. Programming ENIAC was unlike modern programming. There were no keyboards, operating systems, or software applications. Engineers programmed the machine by physically rewiring panels and configuring thousands of switches by hand. This video explores: • Why ENIAC was built during World War II • How it solved complex ballistic calculations • The engineering challenges of using thousands of vacuum tubes • The contributions of the six women who programmed the machine • ENIAC's influence on every modern computer that followed Although technology has advanced dramatically since 1946, the principles demonstrated by ENIAC became the foundation of modern electronic computing. #ENIAC #ComputerHistory #HistoryOfComputing #Technology #Engineering #Programming #WorldWarII #DigitalHistory #Computers #Innovation
