Explanation: An interaction model is dynamic because it depicts how users or system components communicate with the system during operation.

• A. system context model
• B. interaction model
• C. environmental model

Explanation: A system context model gives a structural view of the system and the other systems in its environment.

• A. Designing system architecture
• B. Developing design models
• C. Specifying interfaces
• D. Developing a debugging system

Explanation: Architecture, design models, and interface specifications are normal steps in moving from a concept to a detailed object-oriented design.

• A. Reconfigure
• B. Shutdown
• C. Powersave
• D. All of the mentioned

Explanation: Reconfiguration, shutdown, and power-saving behavior can all be handled by system-control functions.

• A. Sequence model
• B. Subsystem model
• C. Dynamic model
• D. Both Sequence and Dynamic model
• E. View Answer

Explanation: A sequence model specifically shows the chronological flow of messages and interactions among objects.

• A. data flow diagram
• B. state transition diagram
• C. control specification
• D. activity diagram

Explanation: A data flow diagram models both the information domain through data flows and the functional domain through processes that transform the…

• A. sequence
• B. condition
• C. repetition
• D. selection

Explanation: The standard structured-programming constructs are sequence, condition or selection, and repetition.

• A. program design language
• B. structured English
• C. pseudocode
• D. all of the mentioned

• A. Implements some functionality
• B. Has explicit dependencies through provides and required interfaces
• C. Communicates through its interfaces only
• D. All of the mentioned

Explanation: A software component encapsulates functionality, declares provided and required interfaces, and communicates with other components through…

• A. List all actions that can be associated with a specific procedure
• B. List all conditions during execution of the procedure
• C. Define rules by indicating what action(s) occurs for a set of conditions
• D. All of the mentioned

Explanation: Developing a decision table involves listing conditions, listing possible actions, and defining rules that map condition combinations to…

• A. Data representation
• B. Logic verification
• C. "Code-to" ability
• D. Automatic processing

Explanation: Data representation concerns how a component’s local and global data is structured and represented.

• A. State transition diagram
• B. Box diagram
• C. ER diagram
• D. None of the mentioned

Explanation: A box diagram, also called a Nassi-Shneiderman diagram, represents sequence, selection, and repetition without permitting arbitrary…

• A. Repetition
• B. Sequence
• C. Condition
• D. None of the mentioned

Explanation: A sequence shows processing steps performed in order, so it is drawn as processing boxes joined by arrows indicating control flow.

• A. Provide for flexible interaction
• B. Allow user interaction to be interrupt-able and undo-able
• C. Show technical internals from the casual user
• D. Design for direct interaction with objects that appear on the screen

Explanation: Showing technical internals to a casual user increases complexity and reduces user control, so it is not a suitable interface-design…

• A. Machine readability
• B. Maintainability
• C. Structure enforcement
• D. Overall simplicity

Explanation: Machine readability means that a notation can be read or processed directly by a computer-based development tool.

• A. Place the user in control
• B. Reduce the user's memory load
• C. Make the interface consistent
• D. All of the mentioned

Explanation: The three classic golden rules are to place the user in control, reduce the user's memory load, and maintain consistency.

• A. User, task, and environment analysis and modeling
• B. Interface design
• C. Knowledgeable, frequent users
• D. Interface validation

Explanation: Interface design normally includes user, task, and environment analysis, interface design, and interface validation.

• A. the design of interfaces between software components
• B. the design of interfaces between the software and human producers and consumers of information
• C. the design of the interface between two computers
• D. all of the mentioned

Explanation: Interface design commonly addresses software-component interfaces and the interaction between software and its human users or information…

• A. design model
• B. user's model
• C. mental image
• D. system image

Explanation: The design model combines the software's data, architectural, interface, and procedural views.
