Manual Calculators What came before computers?
- Counting aids keep track of quantities
- Many transactions required calculations
- A manual calculator called an abacus first
appeared around 1200 in China, and then in Japan
around 1600 - Other manual calculators include the oddly-named
Napiers Bones, and the slide rule - In 1621, an English mathematician named William
Oughtred used Napiers logarithms to construct
the first slide rule

Mechanical Calculators When did machines begin
to perform calculations?
- A mechanical calculator implements algorithms
autonomously. To work a mechanical calculator,
the operator simply enters the numbers for a
calculation, and then pulls a lever or turns a
wheel to carry out the calculation - Wilhelm Schickard created a mechanical calculator
(called Shickards Calculator) - Blaise Pascal developed the Pascaline
- Leibniz Calculator
- deColmars Arithmometer became the first
mass-produced calculator

When did calculating devices begin to operate
without human power?
- Charles Babbage proposed a device called the
Difference Engine that would operate using steam
power - The Difference Engine was intended to quickly and
accurately calculate large tables of numbers used
for astronomical and engineering applications - In 1834, Babbage began designing a new
general-purpose calculating device, called the
Analytical Engine

When did calculating devices begin to operate
without human power?
- Computer historians believe that the Analytical
Engine design embodies many of the concepts that
define the modern computer - Store the programs and data for calculations on
punched cards - The U.S. Census Bureau held a competition to find
a way to tabulate the 1890 census - Herman Hollerith won the competition with a
design for an electronic punched card tabulating
device

When did calculating devices begin to operate
without human power?
- Each card contained areas to represent fields,
such as nationality. - Once punched, the cards were fed into a card
reader that used an array of metal rods to
electronically read the data from the cards and
tabulate the results, Hollerith Tabulating
Machine - Hollerith incorporated The Tabulating Machine
better known today as IBM

Computer Prototypes Who invented the computer?
- A prototype is an experimental device that
typically must be further developed and perfected
before going into production and becoming widely
available - The Atanasoff-Berry Computer (ABC) was the first
to use vacuum tubes instead of mechanical switches

Who invented the computer?
- Konrad Zuse developed a computer called the Z3,
which was based on the idea of binary yes/no
states-what we now call bits - Howard Aiken created the IBM Automatic Sequence
Controlled Calculator (ASCC), but it is usually
referred to as the Harvard Mark I because it was
moved to Harvard University shortly after
completion

Were prototypes able to perform any real
computing?
- In 1943, a team of British developers created
COLOSSUS, an electronic device designed to decode
messages encrypted by the German ENIGMA machine - COLOSSUS successfully broke the codes and gave
the Allies a major advantage during World War II - In 1943, a team headed by John W. Mauchly and J.
Presper Eckert started work on ENIAC, a gigantic,
general-purpose electronic computer - ENIAC (Electronic Numerical Integrator and
Computer) was designed to calculate trajectory
tables for the U.S. Army

Generations of Computers What was the first
commercially successful computer?
- A computer called the UNIVAC is considered by
most historians to be the first commercially
successful digital computer - Eckert-Mauchly Computer Corp constructed it
- At fourteen and a half feet long, seven and a
half feet high, and nine feet wide, UNIVAC was
physically smaller than ENIAC, but more powerful
Page 391

How did computers progress from room-sized
behemoths to modern personal computers?
- As technology evolved, relay switches and vacuum
tubes were replaced with smaller, less
power-hungry components - Computer historians seem to generally agree that
computers have evolved through four distinct
generations, and in each generation, computers
became smaller, faster, more dependable, and less
expensive to operate
Page 391
20Computer History
Section A
Chapter 8
What characterized the first generation of
computers?
- First-generation computers can be characterized
by their vacuum tubes - A vacuum tube is an electronic device that
controls the flow of electrons in a vacuum - They consumed a lot of power
- They also tended to burn out quickly
- First-generation computers were characterized by
custom application programs - First-generation computers did not seem ready for
prime time

How did second-generation computers differ from
first-generation computers?
- Second-generation computers used transistors
instead of vacuum tubes - Transistors performed functions similar to vacuum
tubes, but they were much smaller, cheaper, less
power hungry, and more reliable - Several successful transistorized computers were
manufactured by companies such as IBM, Burroughs,
Control Data, Honeywell, and Sperry Rand - IBM developed operating systems that provided
standardized routines for input, output, memory
management, storage, and other resource
management activities.

How did second-generation computers differ from
first-generation computers?
- Early proprietary operating systems were designed
to work only on a particular computer - Second-generation computers also ran programming
language compilers that allowed programmers to
write instructions using English-like commands. - High-level languages, such as COBOL (Common
Business-Oriented Language) and FORTRAN (Formula
Translator), were available for use on
second-generation computers
Page 393

What are the characteristics of
third-generation computers?
- Third-generation computers became possible in
1958, when Jack Kilby at Texas Instruments and
Robert Noyce at Fairchild Semiconductor
independently developed integrated circuits - RCA Spectra 70, IBM 360
- In 1965, Digital Equipment Corp.(DEC) introduced
the DEC PDP-8, the first commercially successful
minicomputer - By 2000, the IBM AS/400 (renamed the iSeries 400)
was one of the few remaining devices that could
be classified as a minicomputer - Today, demand for minicomputers is satisfied by
high-end personal computers and servers, and the
term minicomputer has generally fallen into
disuse

How did microprocessor technology affect the
computer industry?
- The technology for fourth-generation computers
appeared in 1971, when Ted Hoff developed the
first general-purpose microprocessor - Early industry leaders included Intel, Zilog,
Motorola, and Texas Instruments - The Intel line, used in most Windows-compatible
computers, included the 8086, 8088, 80286, 80386,
80486, Pentium, and Itanium microprocessors

parts to produce clones of IBM-compatible
computers - These companies were also able to obtain
essentially the same operating system used by IBM
- The IBM PC used an operating system called PC-DOS
that was created by a young programmer named Bill
Gates - Although hobbyists and the business community had
embraced computers, these machines were still
considered difficult for the average person to use

Industry Overview Is there a difference
between the computer industry and the information
technology industry?
Chapter 8
- Computer industry encompasses those companies
that manufacture handheld computers, personal
computers, high-end workstations, servers,
mainframes, and supercomputers - Information technology industry (or IT industry),
is typically used to refer to the companies that
develop, produce, sell, or support computers,
software, and computer-related products
Page 397
44The Computer and IT Industries
Section B
Chapter 8
Is every company that used computers part of
the IT industry?
- No. A bank uses computers, but it is classified
as part of the banking industry - A clothing store might use computers to track
inventory, but it is classified as part of the
apparel industry
Page 397
45The Computer and IT Industries

Chapter 8
What kinds of companies are included in the IT
industry?
- Equipment manufacturers
- Chipmakers
- Software publishers
- Service companies
- Retailers
- Although some companies fit neatly into one of
the above categories, other companies operate in
two or more areas - The IT industry also encompasses large
conglomerates with one or more divisions devoted
to computer hardware, software, or services
Page 398
46The Computer and IT Industries

Chapter 8
What about dot coms?
- The 1990s spawned a group of Internet-based
companies that came to be called dot coms, from
the companies domain names, which inevitably
ended with .com and many of the companies even
incorporated .com into their official company
names - Amazon.com was one of the first Internet-based
companies - Unless a dot com sells computers, peripherals,
or software online, it is probably not considered
part of the computer industry, experts disagree
whether dot coms rightfully belong to the IT
industry

Is the IT industry located in Silicon Valley?
- IT industry heavyweights such as Cisco, Intel,
Sun Microsystems, Oracle, Hewlett-Packard, Palm,
Handspring, Apple, AMD, 3Com, and Silicon
Graphics are all located in Californias Silicon
Valley - Although Silicon Valley has a reputation as the
home of the IT industry, many of the top IT
players are located elsewhere

- Many of the largest companies in the IT industry
have branch offices all over the world - Despite the increasing globalization of the IT
industry, it is still dominated by the U.S.
Sixty-eight percent of IT workers are in the
U.S., even though 62 percent of industry sales
are to non-U.S. companies

Where can I find information about the IT
industry?
- You can dig up lots of information on IT and
computer companies from a wide variety of
computer and business publications - The type of computer publication you need depends
on the kind of information you want - The IT Sources InfoWeb provides you with an
up-to-date guide to publications and other IT
industry resources
Page 400

Economic Factors How has the IT industry
affected the economy?
- The IT industry has been described as the most
dynamic, most prosperous, most economically
beneficial industry the world has ever known. - GDP is defined as the total value of a nations
goods and services produced within a specific
time period - In the U.S., for example, the IT industry
accounted for about 5 percent of the growth in
the 1985 GDP. - The Internet added more fuel to the fire, and by
2000, ITs total contribution to GDP growth was
about 8.6 percent
Page 400
52The Computer and IT Industries

How has the IT industry affected the economy?
- The IT industry produced 1/3 of the real economic
growth, and almost half of all growth between
1995 and 1999 - The world IT market grew at an annual rate of 10
between 1987 and 1995 nearly twice the rate of
the world GDP - In 2000, IT industry growth in the U.S. slowed
due to the dot com sector shakeout

What accounts for the success of the IT
industry?
- Population Growth
- The worldwide population more than doubled over
the past 50 years, and a recent study predicts
that the population will peak at 9 billion by the
year 2070 - Globalization
- As businesses globalize, they encounter new
competitors with technological advantages
Page 401
54The Computer and IT Industries

Chapter 8
What accounts for the success of the IT
industry?
- Governments and private businesses have
discovered that they can become much more
efficient with a liberal application of computers
and other information technologies - Bottom line if your business competitors turn
to technology, so must you
Page 401
55The Computer and IT Industries

Chapter 8
Product Development Whats the reason for the
amazing number of new computer products that
appear each year?
- IT manufacturers and publishers introduce new
products for the same reasons as their
counterparts in the automotive industry. New
products, such as a computer with a faster
microprocessor, a DVD player, or an upgrade to
Windows, are designed to attract customers and
generate sales - In contrast to the automotive industry, however,
the IT industry is not on an annual cycle
Page 402
56The Computer and IT Industries
Section B
Chapter 8
Whats the reason for the amazing number of new
computer products that appear each year?
- The equipment-manufacturing segment of the IT
industry is relatively young, and technology,
rather than marketing, is the major force that
drives product development - Companies cannot always predict when a new
technology will appear, or how it might be
incorporated into new products. As a result, the
life cycle of computer hardware and some computer
products is short, whereas other products have a
long life cycle
Page 402
57The Computer and IT Industries
Section B
Chapter 8
What are the stages in the life cycle of a
typical hardware product?
- The life cycle of a new computer model typically
includes five stages product development,
product announcement, introduction, maintenance,
and retirement
Page 402
58The Computer and IT Industries
Section B
Chapter 8
What are the stages in the life cycle of a
typical hardware product?
- Product Development - Product development often
takes place under wraps. - Product Announcement - Sometime during the
development process, a company makes a product
announcement to declare its intention to
introduce a new product. Vaporware, are
announced, but never produced - Introduction - When a new product becomes
available, it is usually added to the vendors
product line and featured prominently in
advertisements
Page 403
59The Computer and IT Industries
Section B
Chapter 8
What are the stages in the life cycle of a
typical hardware product?
- Maintenance - As supply and demand for a product
reach an equilibrium, the price of the product
decreases slightly. This discounted price is
usually referred to as the street price - Retirement - Gradually, a companys oldest
products are discontinued as demand for them
declines

Chapter 8
Is the life cycle of a software product similar
to that of a hardware product?
- Software begins with an idea that is shaped by a
design team and marketing experts - Most software products undergo extensive testing
before they are released - The first phase of testing, called an alpha test,
is carried out by the software publishers
in-house testing team - Errors, or bugs, found during the alpha test
phase are fixed, and then the software enters a
second testing phase called a beta test - A beta test is conducted by a team of off-site
testers
Page 404
62The Computer and IT Industries
Section B
Chapter 8
Is the life cycle of a software product similar
to that of a hardware product?
- A newly published software package can be an
entirely new product, a new version (also called
a release) with significant enhancements, or a
revision designed to add minor enhancements and
eliminate bugs found in the current version - Unlike computer hardware products, older versions
of software typically do not remain in the
vendors product line

Chapter 8
How do computer companies stack up against each
other?
- Market share refers to a companys share, or
percentage, of the total market pie - Competition is fierce in all segments of the
industry, and market share is one indicator of a
companys success. - Usually defines three tiers
- Top tier Well known, established, large share
- 2nd tier smaller but significant share, newer
- 3rd tier start-up, technology driven
- Computer prices vary by tier Why?

Marketing Channels Why are computer equipment
and software sold through so many outlets?
Page 406
66The Computer and IT Industries
Section B
Chapter 8
Why are computer equipment and software sold
through so many outlets?
- Hardware manufacturers and software publishers
try to reach consumers by making their products
available through a variety of sources - Computer hardware and software are sold through
marketing outlets called marketing channels - These channels include computer retail stores,
mail-order/Internet outlets, value-added
resellers, and manufacturer direct
Page 406
67The Computer and IT Industries
Section B
Chapter 8
Isnt a computer retail store the best channel
for hardware and software products?
- A computer retail store purchases computer
products from a variety of manufacturers, and
then sells those products to consumers - A computer retail store is often the best
shopping option for buyers who are likely to need
assistance after their purchases such as
beginning computer users, or those with plans for
complex computer networks - Retail stores can be a fairly expensive channel
for hardware and software
Page 406
68The Computer and IT Industries
Section B
Chapter 8
How does the mail-order channel compare to
retail?
- Mail order is a special instance of retailing in
which a vendor takes orders by telephone or from
an Internet site - Mail-order suppliers generally offer low prices,
but might provide only limited service and
support - Experienced computer users who can install
components, set up software, and do their own
troubleshooting are often happy with mail-order
suppliers
Page 407
69The Computer and IT Industries
Section B
Chapter 8
Dont some manufacturers and publishers sell
direct?
- One advantage of direct sales is that by cutting
out the retailer, a manufacturer can make more
profit on each unit sold. The disadvantage is
that the manufacturer must provide customers with
technical supporta potentially costly service
that requires large teams of technical support
personnel
Page 407
70The Computer and IT Industries
Section B
Chapter 8
Whats a VAR?
- VAR stands for value-added reseller. A
value-added reseller combines commercially
available products with specialty hardware or
software to create a computer system designed to
meet the needs of a specific industry
Page 408
71The Computer and IT Industries
Section B
Chapter 8
Dont all those channels confuse consumers?
- Consumers can benefit from a variety of channels
- Although consumers benefit from a variety of
channels, vendors within the channels often find
that their sales are pirated by other channel
vendorsa process referred to as channel conflict

Industry Regulation Is the IT industry
regulated in any way?
- Some aspects of the IT industry are regulated by
government agencies, but many aspects are self
regulated - The Federal Communications Commission (FCC)
regulates interstate and international
communications by radio, television, wire,
satellite, and cable - The U.S. Federal Trade Commission and Department
of Justice police the business practices of the
IT industry - Many governments are enacting laws that restrict
access to particular Internet activities and
content

How does the IT industry perceive government
regulation?
- Most IT industry leaders oppose further
regulation of their industry. They remain
skeptical of government regulations that might
limit their ability to explore new technologies
and offer them to the public. To avoid further
government intervention, the IT industry has
taken steps toward self regulation - The information Technology Industry Council has
become one of the major trade associations for
computer manufacturers, telecommunications
suppliers, business equipment dealers, software
publishers, and IT service providers
