Q621.
What are process structure diagrams (PSDs) in JSD?

a.

Hierarchical diagrams

b.

A set of entities

c.

A time-ordered sequence of actions

d.

A process that models the life cycle of the entity

Discuss
Answer: (a).Hierarchical diagrams Explanation:PSDs (Process Structure Diagrams) are hierarchical diagrams that resemble the structure diagrams of JSP, and are used to depict the life cycle of an entity in JSD.
Q622.
How are PSDs (Process Structure Diagrams) different from traditional finite state diagrams?

a.

PSDs have nodes that denote states while traditional finite state diagrams have nodes that denote state transitions

b.

PSDs have nodes that denote state transitions while traditional finite state diagrams have nodes that denote states

c.

PSDs have pseudocode equivalent called structure text

d.

PSDs have nodes that denote state transitions and arrows that denote states

Discuss
Answer: (b).PSDs have nodes that denote state transitions while traditional finite state diagrams have nodes that denote states Explanation:In a PSD (Process Structure Diagram), nodes denote state transitions and arrows denote states, while in traditional finite state diagrams, the bubbles (nodes) represent possible states of the entity being modeled and the arrows denote possible transitions between states.
Q623.
How are entities modeled in JSD(Jackson System Development)?

a.

Through a linguistic stance

b.

Through a set of entities

c.

Through a time-ordered sequence of actions

d.

Through a process that models the life cycle of the entity

Discuss
Answer: (a).Through a linguistic stance Explanation:In JSD(Jackson System Development), entities are modeled through a linguistic stance, using notes, documentation, interviews, and other information sources to create a preliminary list of actions and entities.
Q624.
What are actions in JSD(Jackson System Development)?

a.

Real-world events

b.

Attributes of entities

c.

Atomic events that can't be further decomposed into subactions

d.

Pseudocode equivalent of PSDs (Process Structure Diagrams)

Discuss
Answer: (c).Atomic events that can't be further decomposed into subactions Explanation:In JSD, actions are events that happen to entities. These actions are part of the life cycle of the entity and respond to events in the real world. They are described as atomic events, meaning they cannot be further decomposed into subactions. The life cycle of an entity is modeled using process structure diagrams (PSDs), which represent the structure of JSD and the sequence of events that occur in the life cycle.
Q625.
What are the two special attributes of entities in JSD?

a.

State vector and process identifier

b.

Life cycle and state vector

c.

Identifier attribute and status attribute

d.

Network stage and system specification diagram

Discuss
Answer: (c).Identifier attribute and status attribute Explanation:Entities have two special attributes: the identifier attribute that uniquely identifies the entity and the status attribute that indicates the entity's status.
Q626.
How is interprocess communication handled in JSD?

a.

By inspecting the state vector of another entity

b.

By passing information through a datastream

c.

By accessing a database

d.

Both a and b

Discuss
Answer: (d).Both a and b Explanation:In JSD, there are two basic mechanisms for interprocess communication: entities may inspect the state vector of another entity and entities may asynchronously pass information to another entity through a datastream.
Q627.
How does the communication between processes occur in the implementation stage of JSD?

a.

By inspecting the state vector of another entity

b.

By passing information through a datastream

c.

By replacing communication with a procedure call

d.

By accessing a database

Discuss
Answer: (c).By replacing communication with a procedure call Explanation:In the implementation stage, the concurrent model is transformed into an executable system, and the communication between processes is replaced by a procedure call so that one process becomes a subordinate of another process.
Q628.
What is the purpose of the Log entity in JSD?

a.

To inspect the state vector of another entity

b.

To keep track of books being borrowed

c.

To replace communication with a procedure call

d.

To pass information through a datastream

Discuss
Answer: (b).To keep track of books being borrowed Explanation:If the system is to log information on books being borrowed, it can be modeled by means of a datastream from the Book entity to the Log entity. The Log entity keeps track of books being borrowed.
Q629.
What is the relationship between processes in JSD?

a.

Independent

b.

Interconnected

c.

Synchronized

d.

FIFO

Discuss
Answer: (b).Interconnected Explanation:During the network stage in JSD, the system is modeled as a network of interconnected processes which is depicted in a system specification diagram (SSD).
Q630.
What is the method for interprocess communication in JSD?

a.

State vector communication

b.

Datastream

c.

Procedure call

d.

Both a and b

Discuss
Answer: (d).Both a and b Explanation:JSD has two basic mechanisms for interprocess communication: state vector communication and passing information through a datastream.
