Q141.
How can a finite state machine be converted into a push down automata?

a.

By including a push-down stack

b.

By including a push-down stack with Push() function

c.

By including a push-down stack with Pop() function

d.

By including a push-down stack with Push() and Pop() function

Discuss
Answer: (c).By including a push-down stack with Pop() function Explanation:A finite state machine be converted into a push down automata by including a push-down stack with Push() and Pop() function. Push-down automata supports unlimited number of states. The availability of stack space and time taken to reach certain states are challenges for push-down automata.
Q142.
____ is responsible for availability of resources on the logical path over which the channel is defined.

a.

Finite state machine

b.

Push-down automata

c.

Agent state machine

d.

Channel control state machine

Discuss
Answer: (d).Channel control state machine Explanation:At the top level, each channel object, mode or personality has a top-level channel-setup state machine. Channel control state machine is responsible for availability of resources on the logical path over which the channel is defined. It is generally referred to as infrastructure state machine.
Q143.
In the software factory, _____ protocol profiles are defined so that combinations of services and applications can work together.

a.

independent

b.

aggregate

c.

mutually consistent

d.

fixed

Discuss
Answer: (c).mutually consistent Explanation:Communication services are a part of software radio architecture. They carry out applications such as internet access and radio-specific applications. Mutually consistent protocol profiles are defined so that combinations of services and applications can work together.
Q144.
A sequence of calls links____ layer with radio application layer.

a.

service

b.

radio infrastructure

c.

hardware

d.

application

Discuss
Answer: (a).service Explanation:A sequence of calls behaves as interface between service layer and radio application layers. It sets up radio applications. It creates link for information services. It is used for bridging in military applications.
Q145.
The software tradeoffs at ____ level of the architecture involve the user.

a.

communication services

b.

radio application

c.

radio infrastructure

d.

hardware

Discuss
Answer: (a).communication services Explanation:Seamless access to facilities of other layers, enhanced capability, enhanced interoperability, easy access to off-the-shelf software products and protocols are few tradeoffs seen in the communication services level of the architecture.
Q146.
_____ translates laptop level display information to a level suitable for handheld device.

a.

Transmission Control Protocol

b.

Graphic User Interface

c.

Simple Network Management Protocol

d.

Wireless Access Protocol

Discuss
Answer: (d).Wireless Access Protocol Explanation:Wireless Access Protocol is a technical standard for accessing information over a mobile wireless network. It is interoperable with different network technologies such as CDMA and GSM. It translates laptop level display information to a level suitable for handheld device.
Q147.
Which of the following is not a facility offered by infrastructure layer?

a.

Synchronization

b.

High speed interconnect

c.

Resource management

d.

Position generation

Discuss
Answer: (b).High speed interconnect Explanation:Infrastructure layer manages the resources of the distributed multiprocessor environment. It simplifies interfaces and entities for efficient deployment. Synchronization, resource management, position generation, and signal path packages are some services facilitated by infrastructure layer.
Q148.
Radio application layer constructs physical and virtual radio channels.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Radio application layer binds distributed objects together into waveforms. It constructs physical and virtual radio channels from paths provided by infrastructure layer. The interface between radio application layer and infrastructure layer is defined by CORBA IDL.
Q149.
Which of the following expression can be used to compute processing demand provided Pif, Ps, Pbs, Pbb and Pmo stands for IF, source, bitstream, baseband, and management overhead processing demand respectively?

a.

P=Pif+Ps+Pbs+Pbb+Pmo

b.

P=Pbb+N*(Pif+Pmo)+Ps+Pbs

c.

P=Pif+N*(Ps+Pbs+Pbb)+Pmo

d.

P=Pif+(Pbs*Pbs*Pbb)+Pmo

Discuss
Answer: (c).P=Pif+N*(Ps+Pbs+Pbb)+Pmo Explanation:P=Pif+N*(Ps+Pbs+Pbb)+Pmo is the expression used to compute processing demand. Processing demand depends on a first-order approximation on the signal bandwidths. It is also influenced by the intricacy of the operations in the IF, baseband, bitstream, and source segments.
Q150.
Resource utilization is the ratio of average _____ to average _____

a.

offered demand, effective capacity

b.

offered demand, offered capacity

c.

effective demand, effective capacity

d.

effective demand, offered capacity

Discuss
Answer: (a).offered demand, effective capacity Explanation:Resource utilization relates processing demand to processing capacity. It is given by the ratio of average offered demand to average effective capacity. It can be estimated for buses, CPUs, storage devices, I/O devices, and DSP chips.
