What was the first computer to perform all calculation using electronics rather than wheels, ratchets, or mechanical switches?
What was the first computer to perform all calculation using electronics rather than wheels, ratchets, or mechanical switches?
The correct option is C ABC
ABC was the first computer to perform all
calculation using electronics rather than wheels, ratchets, or mechanical
switches.
The Atanasoff–Berry Computer (ABC) was the first
automatic electronic digital computer, an early electronic digital computing
device that has remained somewhat obscure. The ABC's priority is debated among
historians of computer technology, because it was neither programmable, nor
Turing-complete.
Atanasoff and Berry's computer work was not widely
known until it was rediscovered in the 1960s, amidst conflicting claims about
the first instance of an electronic computer. At that time ENIAC, that had been
created by John Mauchly and J. Presper Eckert, was considered to be the first
computer in the modern sense, but in 1973 a U.S. District Court invalidated the
ENIAC patent and concluded that the ENIAC inventors had derived the subject
matter of the electronic digital computer from Atanasoff (see Patent dispute).
The ABC was built by Atanasoff and Berry in the
basement of the physics building at Iowa State College during 1939–42. The
initial funds were released in September, and the 11-tube prototype was first
demonstrated in October 1939. A December demonstration prompted a grant for
construction of the full-scale machine.
