38 History of Computers

39 The first true calculating machine was the __________, which was in use before 400 BC and is still used in some countries. Abacus

40 In 1617, a Scottish mathematician named John Napier developed a set of calculating rods made of bone or ivory, nicknamed ______________. Napier’s Bones

41 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

42 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.

43 The winner was Herman Hollerith, who invented the __________ ________ and formed the company that later became the giant International Business Machines (IBM) Corporation. Punched Card

44 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

45 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

46 Several machines were built at about the same time
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. Mark I ENIAC EDVAC

47 These early machines were one-of-a-kind, and each had it’s 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 1951. UNIVAC

48 IBM and the seven dwarfs
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

49 The first-generation computers were huge and expensive
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

50 These early computers used several electromechanical parts
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 __________. Relay Solenoid

51 On one occasion, a relay failed
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

52 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 1947. Transistor

53 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

54 In 1958, Jack Kilby of Texas Instruments developed the first ________ ________. _________ _________ combine a number of individual transistors into a single unit. Integrated Circuit Integrated Circuits

55 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 Micro-processor Personal

56 A number of companies, including _________ ________, ______ ______, and _____________, were producing ________ computers by 1977. Apple Computer Radio Shack Commodore Personal

57 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

58 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.

60 Types of Computers

61 Special-purpose General-purpose
There are two basic categories of computers, ___________ __________ and ____________ _________. Special-purpose General-purpose

64 Supercomputers Mainframes Minicomputers Microcomputers
Computers come in four main sizes; ________________________, ________________________. Supercomputers Mainframes Minicomputers Microcomputers

65 Supercomputers ______________ are the largest and fastest. They are used for large projects such as national or global weather forecasting, satellite tracking, etc.

66 Mainframe ______________ computers are very powerful and can be as large as an entire room.

67 They are used, for example, by banks to keep track of millions of checks and deposits, by airlines to schedule thousands of flights and make seat reservations, and by governments to keep track of their citizens. Mainframes usually have terminals connected to them. A terminal consists of a monitor and keyboard that allow a person to enter information and retrieve it from the computer.

68 Minicomputers ______________ are smaller and are sometimes used in medium-size companies to run their manufacturing plants or keep track of inventories. They also have terminals attached to them.
