What was the very first computer?
The first mechanical computer, The Babbage Difference Engine, was designed by Charles Babbage in 1822. The ABC was the basis for the modern computer we all use today. The ABC weighed over 700 pounds and used vacuum tubes.
Why ENIAC is the first computer?
In 1942, physicist John Mauchly proposed an all-electronic calculating machine. The result was ENIAC (Electronic Numerical Integrator And Computer), built between 1943 and 1945—the first large-scale computer to run at electronic speed without being slowed by any mechanical parts.
What was the first computer before ENIAC?
Atanasoff-Berry Computer
Atanasoff-Berry Computer (ABC), an early digital computer. It was generally believed that the first electronic digital computers were the Colossus, built in England in 1943, and the ENIAC, built in the United States in 1945.
