TRUE / FALSE
1. Data and information are essentially the same thing.
a. True
b. False
ANSWER: False
DIFFICULTY: Easy
REFERENCES: 1-2 Data versus Information
LEARNING OBJECTIVES: 01.01 - Define the difference between data and information
RATIONALE: Data is raw, unprocessed facts, whereas information is data that has been
processed and given meaning. They are fundamentally different concepts.
2. Data processing can be as simple as organizing data to reveal patterns.
a. True
b. False
ANSWER: True
DIFFICULTY: Easy
REFERENCES: 1-2 Data versus Information
LEARNING OBJECTIVES: 01.01 - Define the difference between data and information
RATIONALE: Even a simple action like sorting or organizing data qualifies as a form of
data processing. This organization can reveal underlying patterns, transforming raw data
into meaningful information.
3. Data is the result of processing raw facts to reveal its meaning.

, a. True
b. False
ANSWER: False
DIFFICULTY: Easy
REFERENCES: 1-2 Data versus Information
LEARNING OBJECTIVES: 01.01 - Define the difference between data and information
RATIONALE: The statement reverses the correct definition. Information is the result of
processing raw data. Data itself is the unprocessed input.
4. When data are entered into a form and saved, they are placed in the underlying database
as knowledge.
a. True
b. False
ANSWER: False
DIFFICULTY: Moderate
REFERENCES: 1-2 Data versus Information
LEARNING OBJECTIVES: 01.01 - Define the difference between data and information
RATIONALE: When data is saved to a database, it is stored as data. "Knowledge" is a
higher-level concept that involves applying information, experience, and context to make
decisions. The stored data is the building block, not knowledge itself.
5. Data constitute the building blocks of information.
a. True
b. False
ANSWER: True
