Coupling is a measure of ----------------of a module or component.

1. Independent (Page 71)
2. Dependent
3. Closeness
4. All of the given

If a problem is identified and fixed at a -------stage in the software development process, it will cost much more than if it was fixed at and --------stage.

1. earlier & later
2. after & before
3. none of the above
4. later and earlier (Page 17)

Once these requirements have been finalized, the ---------------- process starts.

1. Components (Page 95)
2. Structures
3. Objecs
4. Classes

Data design actually begins during the creation of the analysis model, not the architectural model.

1. False

System Architecture is important to consider because it helps in making -----------

1. Mutual communication.
2. Early design decisions.
3. Reusable abstraction of a system.
4. All of the above (Page 118)

2. structure (Page 117)
3. unification

Cohesion is about making sure each component does _____ thing and does it well.

1. three
2. two
3. infinite

Following are some statements associated with data flow diagrams. Identify the correct statement from among them.

1. DFDs are used to model complex interfaces.
2. DFDs are used to represent only functional processing, data stores and data movements between functions. DFD over flow charts(Page 2)
3. DFDs depict only processes which can be decomposed.
4. DFDs do not show external data sources and external data sinks

The data flow diagram must be augmented by descriptive text in order to describe the functional requirements for a software product.
