Q41.
Adaption may be pre-programmed.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Awareness enables adaption. Adaption is ability to direct a change according to input obtained from sensing. Adaption may be achieved without introducing learning through pre-programming. However, it is not possible to program all possible changes hence the next level of capability cognition is required.
Q42.
What method may introduce a trade-off between time and space in cognitive radio structure?

a.

Introduction of fully programmed solutions

b.

Introduction of partial solutions

c.

Introduction of real time solutions

d.

Introduction of large memory

Discuss
Answer: (b).Introduction of partial solutions Explanation:The introduction of partial solutions help in solving complex problems because a subset of problems relating to the complex problem will be solved first. The number of calculations may not be completely reduced but there is slight development in the overall computational burden.
Q43.
What is the full form of NP complexity?

a.

Non-deterministic polynomial time

b.

Non-linear polynomial time

c.

Non-probabilistic polynomial time

d.

Non-trainable polynomial time

Discuss
Answer: (a).Non-deterministic polynomial time Explanation:The non-deterministic polynomial time is a complexity class in the computational complexity theory. It is used to differentiate decision problems. NP is a collection of decision problems. When a decision results in action, it must have proof that can be confirmed in polynomial time by a deterministic Turing machine.
Q44.
Which among the following is a characteristic that need not be compulsorily present to overcome self-referential inconsistency in cognitive radio?

a.

Definition of process as a priori tightly bounded time epochs

b.

Step counting function

c.

Susceptible to Gödel-Turing condition

d.

Pre-defined actions that uses O (1) resources

Discuss
Answer: (c).Susceptible to Gödel-Turing condition Explanation:In order to computationally support real time transmission and reception, a process must be defined in priori tightly bounded time epochs. A pre-defined action that uses O (1) resources is defined in advance and a reliable step counting function must be present. This will help in avoiding unpredictable usage of resources and unpredictable self-referential loops.
Q45.
What kind of decision relies on external confirmation?

a.

Tactical decision

b.

Independent decision

c.

Predictable decision

d.

Tentative decision

Discuss
Answer: (d).Tentative decision Explanation:Tentative decisions are consulted with the user for confirmation before execution. This leads to better user experience in the future. In certain situations, the selected option is executed and the user interaction is recorded to resolve conflict.
Q46.
The decision phase controls the timing of alerts in a radio.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Other than selecting a particular option from a set of plans, the decision phase chooses the timing to alert a user. It might alert immediately or put off the interruption according to the circumstances of the user (such as until after a meeting).
Q47.
What function belongs to external oriented actions in act phase?

a.

Parse images and videos

b.

Compose messages for interaction with environment

c.

Parse incoming RF signals

d.

Parse texts

Discuss
Answer: (b).Compose messages for interaction with environment Explanation:The function of the act phase is to engage in contact with outside world by composing messages for interaction with the local environment. The message may also have to be transferred to another cognitive radio or to a cognitive node.
Q48.
Which among the following may be used to represent information that is continuously changing?

a.

Knowledge Manipulation Language

b.

Web Ontology Language

c.

RoXen Macro Language

d.

Radio eXtensibleMarkup Language

Discuss
Answer: (b).Web Ontology Language Explanation:Web Ontology Language is a family of knowledge representation languages for developing ontologies. Ontologies are similar in structure to class hierarchies in object-oriented programming. Ontologies are suitable for information that changes continuously such as the data found on the Internet.
Q49.
What forms the constituents of ontology in Web Ontology Language?

a.

Individuals and groups

b.

Individuals and property assertions

c.

Groups and property assertions

d.

Characteristics and property assertions

Discuss
Answer: (b).Individuals and property assertions Explanation:Ontology in Web Ontology Language is composed of individuals and property assertions that associate the individuals to each other. The ontology is controlled by axioms that assign constraints on individuals and their relationship.
Q50.
What does the term “performatives” refer to Knowledge based Query and Manipulation Language?

a.

Operations performed on supporting devices

b.

Operations performed on radio knowledge

c.

Operations performed on radio hardware

d.

Operations restricted to radio self

Discuss
Answer: (b).Operations performed on radio knowledge Explanation:Knowledge based Query and Manipulation language supports communication among software agents and knowledge based systems. The KQML message format and protocol allows a radio to perform operations and utilize the knowledge available in another radio.
