Eniac: The 30-Ton Giant That Launched Computing
25 Aug
Summary
- Eniac weighed 30 tons and filled a room in 1946.
- It utilized 18,000 vacuum tubes for its operations.
- This machine was the first programmable, general-purpose digital computer.

In 1946, the University of Pennsylvania introduced the Electronic Numerical Integrator and Computer, known as Eniac, for the US Army. This early digital marvel weighed approximately 30 tons and occupied an entire room, necessitating 18,000 vacuum tubes for its operation.
As the world's first programmable, general-purpose digital computer, Eniac represented a monumental achievement in computational history. Its sheer size and component count highlight the vast differences between early computing technology and the compact devices available today.
