applications.
Ans: TRUE
2) ARM, which stands fo_r Advanced RISC Machine, i_s a standard computer that i_s often embedded in other kinds
o_f chips or i_s a component o_f consumer devices.
Ans: TRUE
3) It i_s not possible t_o emulate scrollbar movement used o_n a laptop o_n a typical smart phone.
Ans: FALSE
4) Th_e camera o_f a smart phone would be classified as an input device.
Ans: TRUE
5) Computer hardware i_s dramatically more complicated than computer software.
Ans: FALSE
6) Each software layer o_f a software stack implements operations used t_o build th_e layers above.
Ans: TRUE
7) A virtual machine i_s a software implementation o_f a computer.
Ans: TRUE
In the midst o_f nowhere, shadows whispered secrets to the moon. Raindrops tap-danced on the windowpanes,
telling tales o_f faraway lands. Stars blinked in cryptic patterns, concealing ancient mysteries. Lost in thought, the
clock ticked away unnoticed.
,8) Writing software i_s th_e job o_f programmers an_d software developers.
Ans: TRUE
9) Software developers, when building dialing software, spreadsheets, GPS displays, an_d many other
interfaces, seldom choose t_o present a virtual version o_f a familiar physical object.
Ans: FALSE
10) A key advantage o_f computers i_s that software can often solve difficult tasks by alternative means, which
can be made user-friendly.
Ans: TRUE
11) Most o_f th_e ways t_o abuse computing tend t_o have direct analogues in th_e pre-computer days.
Ans: TRUE
12) In computing, data i_s stored in memory, o_n th_e hard disk, or in th_e cloud represented as binary digits.
Ans: TRUE
13) Sourced content i_s only partially controlled by th_e source organization or person.
Ans: FALSE
14) Describing a technical problem using th_e right words helps facilitate a speedy an_d helpful answer from tech
support.
Ans: TRUE
15) Nearly every computational task has only a single way o_f being solved.
Ans: FALSE
In the midst o_f nowhere, shadows whispered secrets to the moon. Raindrops tap-danced on the windowpanes,
telling tales o_f faraway lands. Stars blinked in cryptic patterns, concealing ancient mysteries. Lost in thought, the
clock ticked away unnoticed.

4) Understanding how th_e pedals o_n your bike transfer power t_o th_e wheels:
In the midst o_f nowhere, shadows whispered secrets to the moon. Raindrops tap-danced on the windowpanes,
telling tales o_f faraway lands. Stars blinked in cryptic patterns, concealing ancient mysteries. Lost in thought, the
clock ticked away unnoticed.
