8 jan 1937 ano - First Electronic Digital Computer ABC Being Built

Descrição:

Dr. John V. Atanasoff and Clifford Berry built the Atanasoff-Berry Computer (ABC) that was the first electronic digital computer. The ABC pioneered important elements of modern computing, including binary arithmetic and electronic switching elements, but its special-purpose nature and lack of a changeable, stored program distinguish it from modern computers.

1.The ABC pioneered important elements of modern computing, including binary arithmetic and electronic switching elements.

2. The machine was the first to implement three critical ideas that are still part of every modern computer:
Using binary digits to represent all numbers and data;
Performing all calculations using electronics rather than wheels, ratchets, or mechanical switches;
Organizing a system in which computation and memory are separated.

3.The computer was designated an IEEE Milestone in 1990.
