World's First Computer

No other invention in human history has changed the world so much that a computer did. It has fundamentally altered the way we humans live.

ENIAC, the world's first digital computer that performed ballistics trajectory calculations for the United States Army

Universally Charles Babbage is credited with the invention of the first computer in the year 1822, but it's a mechanical one.


Before I proceed further, let me clarify this upfront. While researching for this article, I found that there are lots of variations of computers.


So, let me tell you what the modern computer is. It is Electrical, Programmable and Digital.


Year 1946: ENIAC (Electronic Numerical Integrator and Calculator)

ENIAC is widely considered as the first computer as it is similar to the modern computer at a fundamental level. It was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania.


It was so freaking huge that it needed a room of about 1800 sq.ft using 18,000 vacuum tubes (used in first generation of computers) with a monstrous weight of almost 50 tons.


Is ENIAC really the first computer? What about Atanasoff-Berry Computer (ABC)?

In the year 1937, a Professor by the name Vincent Atanasoff and his graduate student Cliff Berry from the Iowa state college, created the ABC computer which could perform binary math and boolean logic.



On 19th October, 1973 ENIAC's patent was ruled invalid, thereby crediting the ABC as the first computer.


Many still consider the ENIAC to be the first digital computer because it was fully functional compared to the ABC.
