Essay About History Of The Computer Industry And First Wooden Abacus

History of the Computer Industry in America
Essay title: History of the Computer Industry in America
Only once in a lifetime will a new invention come about to touch
every aspect of our lives. Such a device that changes the way we work,
live, and play is a special one, indeed. A machine that has done all
this and more now exists in nearly every business in the U.S. and one
out of every two households (Hall, 156). This incredible invention is
the computer. The electronic computer has been around for over a
half-century, but its ancestors have been around for 2000 years.
However, only in the last 40 years has it changed the American society.
>From the first wooden abacus to the latest high-speed microprocessor,
the computer has changed nearly every aspect of peopleХs lives for the
better.
The very earliest existence of the modern day computerХs
ancestor is the abacus. These date back to almost 2000 years ago. It
is simply a wooden rack holding parallel wires on which beads are
strung. When these beads are moved along the wire according to
“programming” rules that the user must memorize, all ordinary arithmetic
operations can be performed (Soma, 14). The next innovation in
computers took place in 1694 when Blaise Pascal invented the first
Тdigital calculating machineУ. It could only add numbers and they had
to be entered by turning dials. It was designed to help PascalХs father
who was a tax collector (Soma, 32).
In the early 1800Хs, a mathematics professor named Charles
Babbage designed an automatic calculation machine. It was steam powered
and could store up to 1000 50-digit numbers. Built in to his machine
were operations that included everything a modern general-purpose
computer would need. It was programmed by–and stored data on–cards
with holes punched in them, appropriately called ТpunchcardsУ. His
inventions were failures for the most part because of the lack of
precision machining techniques used at the time and the lack of demand
for such a device (Soma, 46).
After Babbage, people began to lose interest in computers.
However, between 1850 and 1900 there were great advances in mathematics
and physics that began to rekindle the interest (Osborne, 45). Many of
these new advances involved complex calculations and formulas that were
very time consuming for human calculation. The first major use for a
computer in the U.S. was during the 1890 census. Two men, Herman
Hollerith and James Powers, developed a new punched-card system that
could automatically read information on cards without human intervention
(Gulliver, 82). Since the population of the U.S. was increasing so
fast, the computer was an essential tool in tabulating the totals.
These advantages were noted by commercial industries and soon
led to the development of improved punch-card business-machine systems
by International Business Machines (IBM), Remington-Rand, Burroughs, and
other corporations. By modern standards the punched-card machines were
slow, typically processing from 50 to 250 cards per minute, with each
card holding up to 80 digits. At the time, however, punched cards were
an enormous step forward; they provided a means of input, output, and
memory storage on a massive
