Solution
Arrange the following in the increasing order of coupling from lowest coupling to highest coupling.
A. Common Coupling
B. Stamp Coupling
C. Control Coupling
D. External Coupling
E. Content Coupling
Choose the correct answer from the options given below:
Solution
Increasing coupling (lower → higher):
-
Stamp coupling (B): modules share a composite data structure but use only parts of it.
-
Control coupling (C): one module controls another via flags/controls.
-
External coupling (D): modules depend on externally imposed formats/protocols/devices.
-
Common coupling (A): modules share global data.
-
Content coupling (E): one module relies on or modifies another’s internal logic (worst).

| List I | List II |
|---|---|
| A. Equivalence Partitioning | I. Measures independent paths in code |
| B. Boundary Value Analysis | II. Divides input into valid/invalid sets |
| C. Cyclomatic Complexity | III. Focuses on limits of input ranges |
| D. Decision Table Testing | IV. In which a number of combinations of actions are tested under varying sets of conditions |
Choose the correct answer from the options given below:
Solution
| Technique | Description | Matching Statement |
|---|---|---|
| A. Equivalence Partitioning | Divides the input domain into valid and invalid partitions. | II – Divides input into valid/invalid sets |
| B. Boundary Value Analysis | Tests the boundaries of input ranges (min/max limits). | III – Focuses on limits of input ranges |
| C. Cyclomatic Complexity | Measures the number of independent paths through the source code. | I – Measures independent paths in code |
| D. Decision Table Testing | Used to test combinations of conditions and corresponding actions. | IV – Tests combinations of actions under varying conditions |
A. Maintainability
B. Usability
C. Integrity
D. Functionality
Solution
McCall’s Quality Model classifies software quality into three main categories:
- Product Operation factors: Correctness, Reliability, Efficiency, Integrity, Usability
- Product Revision factors: Maintainability, Flexibility, Testability
- Product Transition factors: Portability, Reusability, Interoperability
- Maintainability ✅ – part of Product Revision factors
- Usability ✅ – part of Product Operation factors
- Integrity ❌ – although in McCall model, it’s not grouped directly with Functionality in this context
- Functionality ✅ – general umbrella factor related to McCall’s quality aspects
✅ Final Answer: A, B and D Only
| List I (Software Quality Characteristic) | List II (Description) |
|---|---|
| A. Reliability | II. Capability of software to maintain its level of performance under stated conditions for a stated period of time. |
| B. Efficiency | III. Relationship between the level of performance of the software and the amount of resources used, under stated conditions. |
| C. Maintainability | IV. Effort needed to make modifications, including corrections, improvements or adaptation of software to changes in environment, requirements and functional specifications. |
| D. Portability | I. Ability to transfer the software from one organization or hardware/software environment to another. |
