Explanation: .NET is a software development platform and framework created by Microsoft, supporting languages such as C# and Visual Basic.

• A. Class and function libraries that implement commonly used abstractions are available for reuse
• B. Shared components are woven into an application at different places when the program is compiled
• C. Large-scale systems that encapsulate generic business functionality and rules are configured for an organization
• D. Systems are developed by configuring and integrating existing application systems

Explanation: COTS reuse involves selecting, configuring, and integrating already available application systems rather than building them from scratch.

• A. Application system reuse
• B. Component reuse
• C. Object and function reuse
• D. None of the mentioned

Explanation: A pattern-matching subsystem reused in another application is a reusable component because it provides a distinct piece of functionality…

• B. Commercial Off-The-Shelf states
• C. Commercial Off-The-System state
• D. None of the mentioned

Explanation: COTS expands to Commercial Off-The-Shelf, referring to ready-made software products sold for general use rather than developed…

• A. system context model
• B. interaction model
• C. environmental model
• D. both system context and interaction

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
• D. both system context and interaction

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

Explanation: Program design language, structured English, and pseudocode are simplified, language-like notations used to communicate algorithms across…

• 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…
