Let us take a look at the history of computers that we know today. The
very first calculating device used was the ten fingers of a m an’s hands. This, in
fact, is why today we still count in tens and multiples of tens.
Then the abacus was invented. People went on using some form of abacus well into the 16th century, and it is still being used in some parts of the
world because it can be understood without knowing how to read.
During the 17th and 18th centuries many people tried to find easy ways
of calculating. J. Napier, a Scotsman, invented a mechanical way of multiplying and dividing, which is now the modern slide rule works. Henry Briggs
used Napier’s ideas to produce logarithm tables which all mathematicians
use today.
Calculus, another branch of mathematics, was independently invented
by both Sir Isaak Newton, an Englishman, and Leibnitz, a German m athematician. The first real calculating machine appeared in 1820 as the result of
several people’s experiments.
In 1830 Charles Babbage, a gifted English mathematician proposed to
build a general-purpose problem-solving machine that he called “the analytical engine.” This machine, which Babbage showed at the Paris Exhibition in
1855, was an attempt to cut out the human being altogether, except for providing the machine with the necessary facts about the problem to be solved.
He never finished this work, but many of his ideas were the basis for building
today’s computers.
By the early part of the 20th century electromechanical machines had
been developed and were used for business data processing. Dr. Herman Hollerith, a young statistician from the US Census Bureau successfully tabulated
the 1890 census. Hollerith invented a means of coding the data by punching
holes into cards. He built one machine to punch the holes and others to tabulate the collected data. Later Hollerith left the Census Bureau and established his own tabulating machine company. Through a series of merges the company eventually became the IBM Corporation.
Until the middle of the 20th century machines designed to manipulate
punched card data were widely used for business data processing. These early
electromechanical data processors were called unit record machines because
each punched card contained a unit of data.
In the mid-1940s electronic computers were developed to perform
calculations for military and scientific purposes. By the end of the 1960s
commercial models of these computers were widely used for both scientific computation and business data processing. Initially these computers
accepted their input data from punched cards. By the late 1970s punched
cards had been almost universally replaced by keyboard terminals. Since
that time advances in science have led to the proliferation of computers throughout our society, and the past is but the prologue that gives us
a glimpse of the future.
