ABC(Atanasoff-Berry Computer)

The first electronic digital computer. Completed in 1942 by lowa State Professor John Atanasoff and graduate student Clifford Berry, it employed many of the principles of all future computers. For example, although physically in the form of rotating drums, its memory used capacitors that were constantly being recharged like today’s dynamic RAM.
