Word Processors and Other Word Tools
Rules of Thumb: Word Processing Is Not Typing
 Use the Return or Enter key only when you must.
 Word wrap moves text to the next line.
 Use tabs and margin guides, not the spacebar, to
align columns.
 WYSIWYG is a matter of degree.
 Text that looks perfectly aligned onscreen may not line
up on paper.

Beyond the Printed Page
Paperless Publishing and the Web
 A common prediction is that desktop publishing—and paper
publishing in general—will be replaced by paperless
electronic media.
Electronic Books and Digital Paper
 The electronic book, or ebook, is a handheld device that can
contain anything from today’s top news stories to lengthy
novels.
 Digital paper, or epaper, is a flexible, portable, paper-like
material that can dynamically display black-and-white text
and images on its surface.

Slide 31
Tomorrow’s Technology and You 8/e
Chapter 5
The Spreadsheet: Software for
Simulation and Speculation
 Formulas can be:
 Relative, so they refer to different cells when they are copied
 Absolute, so the formula references never change when they are copied
When the formula in column B
is copied to column C,
it changes relative to the new
column.

entered in column E
or F the value of the
related formula in
column G is
automatically
updated.

Computer Simulations: The Risk
 GIGO Revisited
 The accuracy of a simulation depends on how closely its mathematical
model corresponds to the system being simulated.
 Some models suffer from faulty assumptions.
 Some models contain hidden assumptions that may not even be obvious
to their creators.
 Some models go astray simply because of clerical or human errors.
 Still, garbage in, garbage out is a basic rule of simulation.

Chapter 5
Calculated Risks: Computer Modeling
and Simulation
 Making Reality Fit the Machine
 Some simulations are so complex that
researchers need to simplify models and
streamline calculations to get them to run
on the best hardware available.
 Sometimes this simplification of reality is
deliberate; more often it’s unconscious.
 Either way, information can be lost, and the
loss may compromise the integrity of the
simulation and call the results into question.

Chapter 5
Calculated Risks: Computer Modeling
and Simulation
 The Illusion of Infallibility
 A computer simulation, whether generated by a
PC spreadsheet or churned out by a
supercomputer, can be an invaluable decisionmaking aid.
 The risk is that the people who make decisions
with computers will turn over too much of their
decision-making power to the computer.
 Risks can be magnified because people take
computers seriously.

I don’t want to sit and move stuff around
on my screen all day and look at figures
and have it recognize my gestures and
listen to my voice. I want to tell it what
to do and then go away; I don’t want to
babysit this computer. I want it to act
for me, not with me.
