The World’s First Digital Computing Giant

The World’s First Digital Computing Giant

Completed in 1945, ENIAC was the first machine to combine electronic speed with true programmability. Unlike its rigid predecessors, this room-sized behemoth could be rewired to solve a massive range of complex mathematical problems.

Before ENIAC, computers were mostly custom-built for one specific task. By making the system Turing-complete, engineers transformed it into the grandfather of all modern PCs. It weighed 30 tons and relied on 18,000 vacuum tubes that famously burned out constantly. Its legacy lives on every time you open an app on your smartphone today.
