Q: Apple invented the mouse, and the Macintosh first introduced the mouse technology to the public.

Q: Following the introduction of Apple Macintosh and Microsoft Windows, the desktop metaphor became the universal way most people thought of using a computer.

Q: Because the Xerox's Alto was targeted at office workers, the metaphor the PARC researchers chose for the GUI was a desktop.

Q: The Alto personal computer, created by the Xerox Palo Alto Research Center (PARC), was the first computer with a Graphical User Interface (GUI).

Q: 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.

Q: 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).

Q: Perfect reproduction is a property of analog information.

Q: Relying on 0s and 1s in representing digital information results in a great disadvantage in creating reproductions.

Q: When we install a new app, we should immediately and intuitively perform two important activities: "clicking around" and "blazing away."

Q: Finding errors in software is easy, but diagnosing the cause is difficult.

Q: All digital information is grouped into types, based on the number of binary digits needed to represent the information.

Q: The primary reason for consistency across computer applications is that certain operations are fundamental to processing information no matter what the application.

Q: Applications, especially from the same vendor (e.g., Microsoft, Google, or Apple), are consistent.

Q: When an operation is processing a series of inputs, the "completion count" gives the tally of the completed instances, or equivalently, the number remaining.

Q: 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.

Q: When the completion time of a computer operation can be predicted, applications typically show an hourglass icon.
