HISTORY
The Analytical engine was a proposed digital mechanical general-purpose
computer designed by English mathematician and computer pioneer Charles
Babbage.[2][3] It was first described in 1837 as the successor to
Babbage's difference engine, which was a design for a simpler mechanical
calculator.[4]
The analytical engine incorporated an arithmetic logic unit, control flow in the
form of conditional branching and loops, and integrated memory, making it the
first design for a general-purpose computer that could be described in modern
terms as Turing-complete.[5][6] In other words, the structure of the analytical
engine was essentially the same as that which has dominated computer design
in the electronic era.[3] The analytical engine is one of the most successful
achievements of Charles Babbage.
Computer architecture is the design of computers, and the great ancestor of
today's Ultra-Modern computing devices was the analytical engine. It was the
first proposed mechanical general-purpose computer designed by the great
computer pioneer Charles Babbage. He was assisted by Lady Ada Lovelace who
was the first one to come up with the basic idea of having a language in order
to operate the proposed machine. Ada Lovelace was tutored by Augustus de
Morgan whose De Morgan's law brought revolution to the world of Boolean .
Charles Babbage
A mathematician, philosopher, inventor and mechanical engineer,
Babbage originated the concept of a digital programmable computer.[2]
Babbage is considered by some to be "father of the computer". He is
credited with inventing the first mechanical computer, the Difference
Engine, that eventually led to more complex electronic designs, though all
the essential ideas of modern computers are to be found in his Analytical
Engine, programmed using a principle openly borrowed from
the Jacquard loom.
Ada Lovelace
Ada Lovelace, was an English mathematician and writer
chiefly known for her work on Charles Babbage's proposed
mechanical general-purpose computer, the Analytical Engine.
She was the first to recognize that the machine had
applications beyond pure calculation.
Johann Von Neumann or more popularly known as John Von
Neumann. This very Hungarian genius was not only a child prodigy who could
divide an 8-digit number by another 8-digit number within just a fraction of
second when he was just about six years old. But also, the great
mathematician who grabbed the full-time professor position at Princeton
University by the age probability not a reader not a lecturer but a full-time
professor by the age of 30.
Alan Turing
Alan Turing figured it out which problems can be solved using
computers. He has widely been considered as the father of
computer science and artificial intelligence since then. Alan
Mathison Turing was an English mathematician, computer
scientist, logician, cryptanalyst, philosopher and theoretical
biologist. Alan Turing figured it out which problems can be
solved using computers. He has widely been considered as the father of computer
science and artificial intelligence since then.
Professor David Brailsford of University of
Nottingham
Professor David Brailsford of University of
Nottingham who has been teaching computer
science for more than 50 years now. And he says
if Turing is the father and Babbage was the
grandfather and if Lady Ada Countess of Lovelace
was the great aunt, then John Von Neumann was
the impossibly talented impossibly charismatic
very wealthy uncle to computing.
