Fluency with Information Technology, 6e (Snyder)
Chapter 2 Exploring the Human-Computer Interface: Face It, It's a Computer
2.1 True/False Questions
1) Feedback is an indication that either the computer is still working or it is done.
2) When the completion time of a computer operation can be predicted, applications typically
show an hourglass icon.
3) A way in which product developers who create technologies minimize learning time is by
creating controls that match our expectations, such as with sliders and dials.
4) When an operation is processing a series of inputs, the "completion count" gives the tally of
the completed instances, or equivalently, the number remaining.
5) Applications, especially from the same vendor (e.g., Microsoft, Google, or Apple), are
consistent.
6) The primary reason for consistency across computer applications is that certain operations are
fundamental to processing information no matter what the application.
7) All digital information is grouped into types, based on the number of binary digits needed to
represent the information.
8) Finding errors in software is easy, but diagnosing the cause is difficult.
9) When we install a new app, we should immediately and intuitively perform two important
activities: "clicking around" and "blazing away."
10) Relying on 0s and 1s in representing digital information results in a great disadvantage in
creating reproductions.
11) Perfect reproduction is a property of analog information.

12) The Placeholder Technique is used to "hide" part of the text that you don't want to tamper
with when using Find/ReplaceAll (F/RA).
13) Many desktop applications, regardless of vendor, share basic features, such as a File menu
and an Edit menu, and furthermore, the items within these menus include the same operations.
14) The Alto personal computer, created by the Xerox Palo Alto Research Center (PARC), was
the first computer with a Graphical User Interface (GUI).
15) Because the Xerox's Alto was targeted at office workers, the metaphor the PARC researchers
chose for the GUI was a desktop.
16) Following the introduction of Apple Macintosh and Microsoft Windows, the desktop
metaphor became the universal way most people thought of using a computer.
17) Apple invented the mouse, and the Macintosh first introduced the mouse technology to the
public.
18) The placeholder technique is a two-step process: hide and restore.
19) Metaphors are essential to computer usage because they guide us in learning and using
software.
20) Mobile devices have abandoned the desktop metaphor in favor of the contact metaphor
1) Using only 0s and 1s means the information can be perfectly:
A) reproduced
B) consistent
C) converted to a placeholder
D) turned into a desktop

B) source information
C) digital information

D) All of the above

8) The mouse was invented by:
A) Steve Jobs and Steve Wozniak at Apple
B) Bill Gates at Microsoft
C) Douglas Engelbart and others at Stanford Research Institute
D) Aung San Suu Kyi in Burma
9) A familiar example of the touch metaphor is:
A) a standard keyboard entry
B) a mouse click selection
C) the Cover Flow mechanism
D) all of the above
10) The gesture described as a quick sweep with the finger leaving the surface is known as a:
A) sweep or swipe
B) drag
C) flick
D) tap
11) The gesture that is typically used to launch an application is a:
A) double tap
B) drag
C) flick
D) two-finger sweep
12) The touch metaphor is truly a new metaphor because it:
A) replaces the mouse with a touch-sensitive screen
B) represents the screen differently with content pushed around
C) enables simple navigation techniques
D) all of the above
13) Which of the following is not an advantage of using Copy/Paste/Edit?
A) It is faster.
B) It works well if the copied content is mostly similar to the desired final content.
C) It is more accurate.
D) It allows the user to recreate the formatting from scratch.

transformed or edited to a new form?
A) target value
B) source value
C) final value

page-pf6
20) Various programs running on the same computer have consistent commands and interface
behavior
A) because software companies tend to reuse the code.
