Question

What is called declarative knowledge?

(a) Declarative knowledge represents a range of values applicable for assigning a variable

(b) Declarative knowledge represents assumed statements

(c) Declarative knowledge asserts and reasons over descriptive factual knowledge

(d) Declarative knowledge represents predicted knowledge

This question was addressed to me in unit test.

I would like to ask this question from Next Generation Wireless Network topic in portion Next Generation Wireless Network of Cognitive Radio

Answer 1

The correct answer is:

(c) Declarative knowledge asserts and reasons over descriptive factual knowledge

Declarative knowledge refers to knowledge that can be expressed in a descriptive, factual manner. It includes information that asserts facts and relationships about the world and can be used for reasoning or inference. It contrasts with procedural knowledge, which involves knowing how to perform tasks or actions. In the context of cognitive radio and wireless networks, declarative knowledge might include facts about network conditions, spectrum availability, interference levels, or regulatory constraints, all of which can be used to make decisions in cognitive radio systems.

• Option (a) is incorrect because declarative knowledge is about facts, not ranges of values for variables.
• Option (b) is incorrect because assumed statements refer more to assumptions or hypotheses rather than factual knowledge.
• Option (d) is incorrect because predictive knowledge is more about anticipating future events, which differs from declarative knowledge focused on factual statements.

Declarative knowledge is critical in many fields, including cognitive radio networks, where it is used for tasks such as spectrum management and decision-making.
