Answer: Analytical engine
The
Analytical engine the first name for computer given by the Charles Babbage in
19 century. He was an English mathematician, philosopher, inventor and
mechanical engineer .The
analytical engine is not a single physical machine but a succession of designs
that he tinkered with until his death in 1871. The Analytical Engine has many
essential features found in the modern digital computer. It was programmable
using punched cards, an idea borrowed from the Jacquard loom used for weaving
complex patterns in textiles. The Engine had a 'Store' where numbers and
intermediate results could be held, and a separate 'Mill' where the arithmetic
processing was performed. It had an internal repertoire of the four
arithmetical functions and could perform direct multiplication and division. It
was also capable of functions for which we have modern names: conditional
branching, looping (iteration), microprogramming, parallel processing,
iteration, latching, polling, and pulse-shaping, amongst others, though Babbage
nowhere used these terms. It had a variety of outputs including hardcopy
printout, punched cards, graph plotting and the automatic production of
stereotypes - trays of soft material into which results were impressed that
could be used as molds for making printing plates.
