3. A professional who maintains all aspects of the system including
hardware, software, and programming is known as a:
A) Network Administrator
B) Database Administrator
C) System Administrator
D) Web Administrator

5. The DIKW hierarchy defines the transition of data to information,
knowledge, and finally to:
A) Wisdom
B) Intelligence
C) Insight
D) Understanding
Correct Answer: Wisdom
Rationale: The DIKW Hierarchy defines the transition of data to information
from knowledge to wisdom. Data becomes information when processed,
information becomes knowledge when put into context, and knowledge
becomes wisdom when applied with experience and understanding.
6. In the DIKW hierarchy, what is the definition of "information"?
A) The input directly received by the user
B) Data that has been processed and given meaning
C) Information that has been put into a context
D) Understanding of the "why" behind knowledge
Correct Answer: Data that has been processed and given meaning
Rationale: In the DIKW hierarchy, information is data that has been inferred
from data; one or more processes have been applied to the data to make it
meaningful.
, 7. In the DIKW hierarchy, "knowledge" is best described as:
A) Raw facts and figures
B) Data that has been processed
C) Information that has been put to use and placed into a context
D) An understanding of why something happens
Correct Answer: Information that has been put to use and placed into a
context
Rationale: Knowledge in the DIKW hierarchy is information that has been put
to use; information placed into a context. It is refined information such that
the user is able to call forth only relevant portions of information when
needed.
8. In the DIKW hierarchy, "wisdom" is best described as:
A) Raw facts and figures
B) Processed data
C) Information placed into a context
D) An understanding of the "why" that comes from knowledge and
experience
Correct Answer: An understanding of the "why" that comes from knowledge
and experience
Rationale: Wisdom in the DIKW hierarchy provides a social setting to
