42. Java uses threads to enable the entire environment to be ______.
- Option : D
- Explanation : Java uses threads to enable the entire environment to be asynchronous. Asynchronous threading is pre-emptive i.e. a thread once start executing a task it can hold it in mid, save the current state and start executing another task (context switching) according to priority and other specified criteria and threading. So, option (D) is correct.
- Option : D
- Explanation : System crashes once in 30 days and need 10 minutes to get repaired. Either convert 30 days into minute or 10 minute into days 30 days = 30 ∗ 24 ∗ 60 minute fraction of time system is not available = (10 / (30 ∗ 24 ∗ 60 )) ∗ 100 = 0.023% Availability = 100 - 0.023 = 99.97% So, option (D) is correct.
44. Match each software lifecycle model in List – I to its description in List – II:
| List – I | List – II |
| I. Code-and-Fix | a. Assess risks at each step; do most critical action first. |
| II. Evolutionary prototyping | b. Build an initial small requirement specifications, code it, then “evolve” the specifications and code as needed. |
| III. Spiral | c. Build initial requirement specification for several releases, then design-and-code in sequence |
| IV. Staged Delivery | d. Standard phases (requirements, design, code, test) in order |
| V. Waterfall | e. Write some code, debug it, repeat (i.e. ad-hoc) |
Codes:
| I | II | III | IV | V | |
| (1) | e | b | a | c | d |
| (2) | e | c | a | b | d |
| (3) | d | a | b | c | e |
| (4) | c | e | a | b | d |
- Option : D
- Explanation :
- In Code-and-Fix model write some code, debug it, repeat (i.e. ad-hoc)
- In Evolutionary prototyping model build an initial small requirement specifications, code it, then “evolve” the specifications and code as needed.
- In Spiral model is assess risks at each step; do most critical action first.
- In Staged Delivery model build initial requirement specification for several releases, then design-and-code in sequence
- In Waterfall model standard phases (requirements, design,code, test) in order
So, option (D) is correct.
45. Match each software term in List – I to its description in List – II:
| List - I | List - II |
| I. Wizards | a. Forms that provide structure for a document |
| II. Templates | b. A series of commands grouped into a single command |
| III. Macro | c. A single program that incorporates most commonly used tools |
| IV. Integrated Software | d. Step-by-step guides in application software |
| V. Software Suite | e. Bundled group of software programs |
Codes:
| I | II | III | IV | V | |
| (1) | d | a | b | c | e |
| (2) | b | a | d | c | e |
| (3) | d | e | b | a | c |
| (4) | e | c | b | a | d |
- Option : A
- Explanation :
- Wizards is Step-by-step guides in application software
- Templates are Forms that provide structure for a document
- Macro is a series of commands grouped into a single command
- Integrated Software is a single program that incorporates most commonly used tools
- Software Suite is bundled group of software programs
So, option (A) is correct.
