Q11.
What type of operations is performed in sleeping behaviour?

a.

No operation

b.

Non incremental machine learning

c.

Incremental machine learning

d.

Current knowledge generation

Discuss
Answer: (b).Non incremental machine learning Explanation:During sleeping behaviour, the radio processes the experience accumulated during the waking behaviour. This is accomplished by using non-incremental machine learning algorithms. It will map the present case integrated knowledge to overall integrated knowledge.
Q12.
What is the responsibility of prayer behaviour?

a.

Invoke sleeping behaviour

b.

Invoke waking behaviour

c.

Resolve conflicts

d.

Erase present input-response behaviour

Discuss
Answer: (c).Resolve conflicts Explanation:When the user chooses to disregard the decision taken by the cognitive radio, it is added to a list of conflicts. These conflicts may be resolved using overall knowledge developed during sleeping behaviour. Otherwise it is added to a list of unresolved conflicts which is resolved during praying behaviour.
Q13.
What language is used by prayer behaviour to work with the home network while resolving a conflict?

a.

Web Ontology Language

b.

Radio Knowledge Representation Language

c.

RoXen Macro Language

d.

Knowledge Query and Manipulation Language

Discuss
Answer: (d).Knowledge Query and Manipulation Language Explanation:Prayer behaviour resolves conflict with the help of home network. The conflict is presented to the network using Knowledge Query and Manipulation Language. If the conflict is resolved, it is integrated into overall knowledge.
Q14.
The entrance of a stimulus invokes a new cognition cycle.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:The entrance of a stimulus invokes a new cognition cycle during the waking behaviour. It is also invoked by the completion of cognition cycle which was already in process. The stimulus is obtained by monitoring the information signals such as voices, images, radio signals, etc.
Q15.
What is the function of the observe phase?

a.

Sense and perceive

b.

Sense and respond

c.

Perceive and respond

d.

Sense and forget

Discuss
Answer: (a).Sense and perceive Explanation:The observe phase interacts with the environment by analysing the input information stream. It may accept multiple inputs from different directions and in different format.
Q16.
What is binding?

a.

Naming each path

b.

Associating a path for each type of input

c.

Developing subsets from multiple inputs

d.

Naming each input

Discuss
Answer: (c).Developing subsets from multiple inputs Explanation:Binding is the process of grouping input from several directions into a single input or into a group of subsets. It helps to assign a priority level for each input such that the time-sensitive operations are completed first for effective performancce.
Q17.
What is the significance of binding?

a.

Less usage of resources

b.

Faster implementation

c.

Easier to process

d.

Easier to compare with prior experience

Discuss
Answer: (d).Easier to compare with prior experience Explanation:The newly formed bindings are compared with prior experience to identify a close match. The binding is then grouped with the prior experience. This is done to detect patterns that could help in prediction, modelling, and decision making.
Q18.
Which among the following is a requirement of observe phase?

a.

Large memory

b.

Large bus

c.

Precise clock

d.

Accurate timer

Discuss
Answer: (a).Large memory Explanation:The cognitive radio requires large reserve of memory for storing all experiences. This means that every audio, video, email, and radio signals for over a year must be available for access in memory. Thus architecture capable of retaining information and rapidly correlating current stimulus with available information is required.
Q19.
What is the function of the orient phase?

a.

Determine the resources required for a process

b.

Determine the weight of a binding

c.

Determine the number of bindings that could be processed

d.

Determine the duration of a process

Discuss
Answer: (b).Determine the weight of a binding Explanation:The orient phase determines the significance or weight of a binding which is formed by associating a stimulus with prior experience. The operations are performed on internal data structures which behave as short term memory.
Q20.
What invokes the change from short term memory to long term memory?

a.

Instruction from user

b.

Internal structure

c.

Environment

d.

Prior experience

Discuss
Answer: (c).Environment Explanation:The environment provides the redundancy required to trigger a transfer from short term memory to long term memory. The sleep cycle moderates the transfer and also analyses the contents of short term memory since the last sleep cycle.
