What was the world’s first general-purpose computer?

The world's first general-purpose computer "ENIAC" was born on February 14, 1946 at the University of Pennsylvania. The inventors are Americans John W. Mauchly and J. Presper Eckert.

The U.S. Department of Defense uses it for ballistic calculations. It is a huge thing, using 18,000 electron tubes, covering an area of ​​170 square meters, weighing 30 tons, consuming about 150 kilowatts of power, and can perform 5,000 operations per second. This seems insignificant now, but at the time it was Unprecedented. ENIAC uses electron tubes as components, so it is also called a tube computer and is the first generation of computers. Because the electron tubes used in electron tube computers are large in size, consume a lot of power, and are prone to heat, they cannot work for too long.

ENIAC, the world's first electronic computer, covers an area of ​​170 square meters, weighs 30 tons, consumes about 150 kilowatts per hour, and can perform 5,000 operations per second. Used by the U.S. Department of Defense for ballistic calculations.
