Matching Software Quality Characteristics
This question requires matching the software quality characteristics listed in List I with their correct descriptions provided in List II. Let's break down each characteristic:
Understanding Reliability
Reliability (A) refers to the software's ability to perform consistently without failures. It's about maintaining its performance level over time under specific conditions.
Looking at List II, description II states: "Capability of software to maintain its level of performance under stated conditions for a stated period of time." This directly matches the definition of Reliability.
Therefore, A matches with II.
Understanding Efficiency
Efficiency (B) focuses on how well the software uses system resources. It measures the performance relative to the resources consumed (like time and memory).
Description III in List II says: "Relationship between the level of performance of the software and the amount of resources used, under stated conditions." This definition perfectly aligns with Efficiency.
Thus, B matches with III.
Understanding Maintainability
Maintainability (C) relates to the ease with which software can be modified after its initial release. Modifications include fixing defects, improving performance, or adapting to new requirements.
Description IV states: "Effort needed to make modifications, including corrections, improvements or adaptation of software to changes in environment, requirements and functional specifications." This is the core definition of Maintainability.
Hence, C matches with IV.
Understanding Portability
Portability (D) describes how easily software can be transferred from one environment (like hardware or operating system) to another.
Description I says: "Ability to transfer the software from one organization or hardware/software environment to another." This accurately defines Portability.
Therefore, D matches with I.
Summary of Matches
Based on the analysis of each characteristic:
| List I Characteristic | List II Description | Match |
|---|---|---|
| A. Reliability | II. Capability of software to maintain its level of performance under stated conditions for a stated period of time. | A-II |
| B. Efficiency | III. Relationship between the level of performance of the software and the amount of resources used, under stated conditions. | B-III |
| C. Maintainability | IV. Effort needed to make modifications, including corrections, improvements or adaptation of software to changes in environment, requirements and functional specifications. | C-IV |
| D. Portability | I. Ability to transfer the software from one organization or hardware/software environment to another. | D-I |
Correct Answer Choice
The correct matching derived is A-II, B-III, C-IV, D-I. This corresponds to the option that lists these pairs.
