Q31.
What is a state transition diagram (STD) used for?

a.

To represent the collection of library members

b.

To represent the balance of the account from which acquisitions are paid

c.

To represent states and transitions in an FSM

d.

To represent the collection of titles ordered but not yet received

Discuss
Answer: (c).To represent states and transitions in an FSM Explanation:A state transition diagram (STD) is used to represent states and transitions in an FSM. States are represented as bubbles with a label and transitions are represented as labeled arcs.
Q32.
What triggers a transition in an FSM?

a.

The collection of library members

b.

The balance of the account from which acquisitions are paid

c.

The return of a book

d.

Input signals from a finite set of possible stimuli

Discuss
Answer: (d).Input signals from a finite set of possible stimuli Explanation:Transitions in an FSM occur on input signals from a finite set of possible stimuli.
Q33.
What is the purpose of Finite State Machines (FSMs)?

a.

To model the collection of library members

b.

To model the balance of the library's account

c.

To model states and state transitions of a system

d.

To model the collection of titles available in a library

Discuss
Answer: (c).To model states and state transitions of a system Explanation:The purpose of FSMs is to model states and state transitions of a system using state-based modeling techniques.
Q34.
What is the initial state in a Finite State Machine (FSM)?

a.

The state of the collection of library members

b.

The state of the collection of titles available

c.

A specially designated state from which the machine starts

d.

The final state

Discuss
Answer: (c).A specially designated state from which the machine starts Explanation:In an FSM, the initial state is a specially designated state from which the machine starts.
Q35.
What is the purpose of state transition diagrams (STD)?

a.

To model the collection of titles available in a library

b.

To model the balance of the library's account

c.

To visually represent the states and transitions of a Finite State Machine (FSM)

d.

To model the collection of library members

Discuss
Answer: (c).To visually represent the states and transitions of a Finite State Machine (FSM) Explanation:State transition diagrams (STD) are used to visually represent the states and transitions of a Finite State Machine (FSM).
Q36.
What is the final state in a Finite State Machine (FSM)?

a.

The initial state

b.

The state of the collection of library members

c.

The state of the collection of titles available

d.

One or more specially designated states

Discuss
Answer: (d).One or more specially designated states Explanation:In a Finite State Machine (FSM), one or more states are designated as final states. The final state could be the one labeled 'written off' or any of the others.
Q37.
What is a state machine diagram in UML?

a.

A representation of a system in terms of states and state transitions

b.

A diagram that models the complete state of the system

c.

A monolithic diagram that becomes difficult to understand

d.

A hierarchical decomposition of FSMs

Discuss
Answer: (a).A representation of a system in terms of states and state transitions Explanation:In UML, FSMs are modeled in the state machine diagram as a representation of a system in terms of states and state transitions.
Q38.
What is the advantage of using state charts to model a system?

a.

It allows for a monolithic representation of the system

b.

It becomes difficult to understand with time

c.

It allows for a hierarchical decomposition of FSMs

d.

It models only a tiny part of the system

Discuss
Answer: (c).It allows for a hierarchical decomposition of FSMs Explanation:In state charts, groups of states can be viewed as a single entity at one level and refined at the next level of abstraction, allowing for a hierarchical decomposition of FSMs.
Q39.
What is the disadvantage of modeling a system in one large and monolithic state transition diagram?

a.

It becomes difficult to understand

b.

It allows for a hierarchical decomposition of FSMs

c.

It models only a tiny part of the system

d.

It is a recommended approach

Discuss
Answer: (a).It becomes difficult to understand Explanation:Modeling a system in one large and monolithic state transition diagram becomes soon unwieldy and difficult to understand, hence not recommended.
Q40.
What is a data flow diagram (DFD)?

a.

A method of functional decomposition with respect to the flow of data.

b.

A black box which transforms some input stream into some output stream.

c.

A tool to represent data flows between processes, external entities and data stores.

d.

A design method mostly used in conjunction with data flow diagrams.

Discuss
Answer: (a).A method of functional decomposition with respect to the flow of data. Explanation:The data flow diagram is defined as a method of functional decomposition with respect to the flow of data. It represents data flows between processes, external entities, and data stores.
