3. Correct answer: E. Lotus 1-2-3, an electronic spreadsheet, was the killer app that made the
IBM PC a must-have business tool.
A is incorrect because Microsoft Word is a word processor that evolved later for the PC but
did not have the killer app effect of Lotus 1-2-3.
B is incorrect because, although VisiCalc was a very important application for users of the
personal computers that predated the IBM PC, and was the obvious model for Lotus 1-2-3, it
did not play the role that Lotus 1-2-3 did in the success of the IBM PC.
C is incorrect because BASIC is a programming language, and although the IBM PC
included a BASIC interpreter in ROM, it was not a compelling must-have business tool.
D is incorrect because PC DOS is an OS and not an application, and it alone could not play
the role that Lotus 1-2-3 did.
4. Correct answer: E. Apple’s iOS is not available as a desktop operating system, used only in
Apple’s mobile devices.
A, B, C, and D are all incorrect because all these OSs (Chrome OS, macOS, Windows 10,
and Linux) are available as desktop operating systems.
5. Correct answers: A and C. Both a mouse and a keyboard are input devices.
B is incorrect because a printer is an output device.
D is incorrect because RAM is a form of computer memory used for temporary storage.
E is incorrect because ROM is a nonvolatile form of computer memory used to store
programs.
6. Correct answer: B. A file and printer server is a networked computer that allows users to save
and access files stored on it.
A, C, D, and E are all incorrect because each of these devices (desktop computer, tablet,
laptop, and smartphone) typically is a client on a network, allowing the local user to connect
to network services.

7. Correct answer: E. SoC, the acronym for system-on-a-chip, describes technology in which all
or most of a device’s electronic circuitry is on a single microchip.
A, IoT, is incorrect. It is the acronym for Internet of Things.
B, UI, is incorrect. It is the acronym for user interface.
C, RAM, is incorrect. It is the acronym for Random Access Memory.
D, SSD, is incorrect because it is the acronym for solid-state drive.
8. Correct answer: B. macOS is built on NextStep, an OS based on the UNIX kernel.
A is incorrect because while Linux is UNIX-like, it is not the basis for OS X.
C is incorrect because DOS is a very old single-tasking OS that is not the basis for macOS.
D is incorrect because Windows is not the OS on which macOS is built.
E is incorrect because Chrome OS is not the OS on which macOS is built.
9. Correct answer: D. A government agency was a typical end user in the 1950s.
A is incorrect because there were no computer gamers (in the modern sense) in the 1950s.
B is incorrect because a medical doctor would not have been a typical computer user in the
1950s.
C is incorrect because a politician would not have been a typical computer user in the 1950s.
E is incorrect because a secretary would not have been a typical computer user in the 1950s.
10. Correct answer: A, IoT, is the acronym for Internet of Things, which describes networked
devices that contain microcomputers, but are not thought of as computing devices.
B, RAM, is incorrect. It is the acronym for Random Access Memory.
C, NTFS, is incorrect. It is the acronym for New Technology File System (NT File System).
D, SSD, is incorrect because it is the acronym for solid-state drive
E, SoC, is incorrect. It is the acronym for system-on-a-chip.
11. Correct answer: D. The computing trend over the last 70-plus years has been toward
physically smaller, more powerful computers.
A is incorrect because the trend has been toward smaller computers, not larger ones.
B is incorrect because the trend has not been toward larger, less powerful computers.
C is incorrect because the trend has not been toward less powerful computers.
E is incorrect because the trend has not been toward single-use computers.

12. Correct answer: B: When using a mobile device, if you touch an area of screen that requires
input from a keyboard, the OS will display a virtual keyboard for your use.
A is incorrect because a help screen would not be as useful as an onscreen keyboard in this
scenario.
C is incorrect because you can use a mobile device without needing to connect to any type of
physical keyboard, although it is possible to use a Bluetooth keyboard with many mobile
devices.
D is incorrect because a mobile device is not going to display a command-line interface
(CLI) for your use when you need a keyboard (virtual or non-).
E is incorrect because screen gestures are not something that is displayed on a screen, but
how you touch a touch screen to interact with the device.
13. Correct answer: B. Using a Wi-Fi connection when browsing the Internet with a mobile
device can save data fees.
A is incorrect because Bluetooth will not usually connect your device to the Internet—just to
other Bluetooth devices located within yards of the mobile device.
C is incorrect because USB is not a wireless network connection.
D is incorrect because connecting to the Internet using a cellular connection will normally
incur data usage fees based on the amount of data downloaded or require an unlimited data
plan.
E is incorrect because Ethernet is not a wireless network.
14. Correct answer: D. NTFS is the default file system for current Windows OSs.
A is incorrect because iOS is Apple’s mobile OS; it is not a file system.
B is incorrect because IC refers to any integrated circuit chip.
C is incorrect because RAM is volatile memory, not a file system.
E is incorrect SSD is not a file system, but a solid-state storage device.
