JUNE 2013 - Paper 3

Instructions:  

This section contains solution for UGC NET Computer Science JUNE 2013 paper . This subsection has answer keys for paper3. 

1:  

The Software Maturity Index (SMI) is defined as
SMI = [Mf - (Fa + Fc + Fd)] / Mf
Where
Mf = the number of modules in the current release.
Fa = the number of modules in the current release that have been added.
FC= the number of modules in the current release that have been changed.
Fd = the number of modules in the current release that have been deleted.
The product begins to stabilize when 

A.

SMI approaches 1

B.

 SMI approaches 0 

C.

SMI approaches =1 

D.

None of the above

 
 

Option: A

Explanation :

Software Maturity Index is that which can be used to determine the readiness for release of a software system. This index is especially useful for assessing release readiness when changes, additions, or deletions are made to existing software systems.
                      SMI can also be a measurement of product stability, when SMI approaches 1.0 the product is stable. When correlated with the time it takes to complete a version of the software, you have an indication of the maintenance effort needed.

Match the following :

a. Watson Felix model                          i. Failure  intensity
b. Quick-Fix  model                               ii. Cost  estimation
c. Putnarn  resource                             iii. Project planning
allocation model                                            
d. Logarithmetic Poisson
Model                                                       iv. Maintenance 
 

Codes 
a    b     c    d

A.

ii     i    iv      iii

B.

i      ii        iv      iii 

C.

ii    i     iii       iv  

D.

ii       iv         iii      i    

 
 

Option: D

Explanation :

Watson and felix model provides an relationship between delivered source lines of code L  and effort  E(person-month)and is given by equation - 
E = 5.2 L0.91
Similarly duration of development D in months is given by  
D=4.1 L0.36
Quick Fix model is  an adhoc approach to maintaining software. It is a fire fighting approach, waiting for the problem to occur and then trying to fix it . 
Putnam model describes the time and effort required to finish a software project of specified size.
Logarithmetic Poisson Model  It is software reliability model that predicts expected failures (and hence related reliability quantities).

3:  

_____________ is a process model that removes defects before they can precipitate serious hazards. 

A.

 Incremental model

B.

Spiral model

C.

Cleanroom software engineering 

D.

Agile model

 
 

Option: C

Explanation :

  • Clean room software engineering (CSE) is a process model that removes defects before they can precipitate serious hazards .
  • Clean room management is based on the incremental model of software development, which accumulates into the final product..
  • The main goal of clean room engineering is to produce zero error-based software by allowing correct designs, which avoid rework.

4:  

Equivalence partitioning is a  method that divides the input domain of a program into classes of data from which test cases can be derived 

A.

White-box testing

B.

Black-box testing 

C.

 Orthogonal- array testing  

D.

Stress testing

 
 

Option: B

Explanation :

  • In a black box testing   the tester only knows the inputs and what would be the expected outcome, he does not know how the program arrives at those outputs. 
  • The tester does not ever examine the programming code and does not need any further knowledge of the program other than its specifications.
