PREVIOUS YEAR SOLVED PAPERS - July 2016 Paper 3
41. Which of the following statements is not correct?
- Option : D
- Explanation :
- HTML is not screen precise formatting language.Correct We need other language to do screen precise formatting.
- HTML does not specify a logic.Correct
- DHTML is used for developing highly interactive web pages.Correct
- Html is not a programming, it is hyper text markup language.
So, option (D) is correct.
42. When one object reference variable is assigned to another object reference variable then
- Option : B
- Explanation : When one object reference variable is assigned to another object reference variable then a copy of the reference is created. For more information Refer:References in C++ Option (B) is correct.
- Option : C
- Explanation : MTBF = 30 days = 30 * 24 = 720 hour. MTTR = 12 hour. Availability(A) = MTBF / (MTBF + MTTR) i.e. A = 720 / (720 + 12) = 0.9836 = 98.36%. So, option (C) is correct.
44. Match the software maintenance activities in List – I to its meaning in List – II.
| List - I | List - II |
| I. Corrective | (a) Concerned with performing activities to reduce the softwarecomplexity thereby improving program understandability and increasing software maintainability. |
| II. Adaptive | (b) Concerned with fixing errors that are observed when the software is in use. |
| III. Perfective | (c) Concerned with the change in the software that takes place to make the software adaptable to new environment (bothhardware and software). |
| IV. Preventive | d) Concerned with the change in the software that takes place to make the software adaptable to changing user requirements. |
Codes:
| I | II | III | IV | |
| (1) | (b) | (d) | (c) | (a) |
| (2) | (b) | (c) | (d) | (a) |
| (3) | (c) | (b) | (d) | (a) |
| (4) | (a) | (d) | (b) | (c) |
- Option : B
- Explanation :
- Corrective Concerned with fixing errors that are observed when the software is in use.
- Concerned with the change in the software that takes place to make the software adaptable to new environment (bothhardware and software).
- Perfective Concerned with the change in the software that takes place to make the software adaptable to changing user requirements.
- Preventive Concerned with performing activities to reduce the software complexity thereby improving program understandability and increasing software maintainability.
So, option (B) is correct.
45. Match each application/software design concept in List – I to its definition in List – II.
| List – I | List – II |
| I. Coupling | (a) Easy to visually inspect the design of the software and understand its purpose. |
| II. Cohesion | (b) Easy to add functionality to a software without having to redesign it. |
| III. Scalable | (c) Focus of a code upon a single goal. |
| IV. Readable | (d) Reliance of a code module upon other code modules. |
Codes:
| I | II | III | IV | |
| (1) | (b) | (a) | (d) | (c) |
| (2) | (c) | (d) | (a) | (b) |
| (3) | (d) | (c) | (b) | (a) |
| (4) | (d) | (a) | (c) | (b) |
- Option : C
- Explanation :
- Coupling is reliance of a code module upon other code modules.
- Cohesion is easy to visually inspect the design of the software and understand its purpose.
- Scalable is focus of a code upon a single goal.
- Readable is easy to add functionality to a software without having to redesign it.
So, option (C) is correct.
