UNIT 4
How the First Computer Was Developed.
The first suggestion that a machine for mathematical computation
could be built was made more than a hundred years ago by the
mathematician Charles Babbage. We now realize that he
u n d e r s t o o d
clearly all the fundamental principles of modem computers.
Babbage was born in Devonshire, England, 1792. He did not receive a
good
education, but he taught himself mathematics so well that when he
went to Cambridge, he found that he knew more algebra than his tutor.

At that time mathematics in Cambridge was still under the influence of
Newton and was quite unaffected by the contemporary developments on
the continent.
Charles Babbage was outstanding among his contemporaries because
he insisted on the practical application of science and mathematics. For
example, he wrote widely on the economic advantages of mass production
and on the development of machine tools.
In 1812 he was sitting in his room looking at a table of logarithms
which he knees to be full of mistakes, when an idea occurred to computing
all tabular functions by machinery. Babbage constructed a small working
model which he demonstrated in 1822.
The Royal Society supported the project and Babbage was promised a
subsidy.
In 1833 he began to think of building a machine which was in fact the
first universal digital computer, as the expression is understood today.
Babbage devoted the rest of his life to an attempt to develop it. He had
to finance all of the work himself and he was only able to finish part of the
machine though he prepared thousands of detailed drawings from which it
could be made.
Babbage wrote more than 80
books and papers, but he was
misunderstood by his contemporaries and died a disappointed man in 1871.
He tried to solve by himself and with his own resources a series of
problems which in the end required the united efforts of two generations of
engineers.
After his death his son continued his
work and built part of an
arithmetic unit, which printed out its results directly on paper.
