History of Computers
The first true calculating machine was the __________, which was in use before 400 BC and is still used in some countries. Abacus
In 1617, a Scottish mathematician named John Napier developed a set of calculating rods made of bone or ivory, nicknamed ______________. Napiers Bones
Charles Babbage, a nineteenth-century English mathematician, designed plans for a _________ _________. His machine consisted of four parts: an input device, a memory (which he called a store), a processor (he called it a mill), and an output device. Although he never built the machine, Babbage developed many of the principles upon which modern computers were developed. Difference Engine
The first major development in computing hardware came when, after the results of the 1880 U.S. Census had taken seven years to tabulate, the Census Bureau held a contest to see if anyone could invent a faster method.
The winner was Herman Hollerith, who invented the __________ ________ and formed the company that later became the giant International Business Machines (IBM) Corporation. Punched Card
In 1910, James Powers, an employee of the Census Bureau, improved on the system; his new company became a major part of the early computer manufacturer Remington Rand which, in turn, added the Sperry and Univac companies and ultimately became _________. Unisys
The punched-card system was the most widely used method for reading information into early programmable computers, which did not arrive on the scene until World War II. This was not because nobody had thought of them, but rather because the early ones were very _________ --- only the Department of Defense, then called the War Department, had enough money to pay for them. Expensive
Several machines were built at about the same time. The most famous was the __________ at Harvard University and the ________ and ________ at the University of Pennsylvania. EDVACENIAC Mark I
These early machines were one-of-a-kind, and each had its peculiarities. The first machine to be mass-produced and sold was the ________, designed by Dr. J. Presper Eckert and Dr. John Mauchly (who had built ENIAC and EDVAC) in UNIVAC
IBM started selling systems two years later. Soon the computer industry became known as ___ ___ ___ ______ ______; other companies came and went rapidly. IBM and the seven dwarfs
The first-generation computers were huge and expensive. Their central processors were made of _________ ______. By modern standards, they were quite slow. Huge air conditioners were required to keep them from burning themselves up. If an air conditioner failed, the computer had to be shut down instantly. Neither the computers nor the air conditioners were very reliable. Only a few of the first-generation computers were sold. Vacuum Tubes
These early computers used several electromechanical parts. One was a _____, a mechanical switch that is activated (switched on or off) by an electrical device called a __________. Solenoid Relay
On one occasion, a relay failed. When the engineer took it apart, he found a dead insect jammed between the switch contacts. This was the source of the term ____ to designate a problem with a computer component --- either hardware or software. Bug
Several Major technical developments followed, each resulting in a new generation of computers. John Bardeen, Walter Brattain, and William Shockley invented the __________ while working at Bell Laboratories in Transistor
Transistors, which replaced _______ _____, made the second generation of computers smaller, faster, and more reliable. Many of these systems were sold to business, industry, and science. Vacuum Tubes
In 1958, Jack Kilby of Texas Instruments developed the first ________ ________. _________ _________ combine a number of individual transistors into a single unit. Integrated Circuit Integrated Circuits
In 1971, engineers at Intel Corporation designed the first _______________. A _______________ puts all the circuits needed for a computer onto a single chip. This development made the _________ computer possible. Micro-processor Personal
A number of companies, including _________ ________, ______ ______, and _____________, were producing ________ computers by Personal Radio Shack Commodore Apple Computer
Introduced in 1981, the ____ personal computer rapidly became a major success. Many other companies began making personal computers and the software to run them. IBM
This competition has forced down prices and made personal computers even more powerful than the largest computers built only a decade ago. New software programs are continually being produced to take advantage of this increased power, and to expand the way in which we use computers.
