UGC NET Computer Science June 2013 Answer key

1. The software maturity index (SMI) is defined as SMI= [M_f - (F_a + F_c + F_d )]/M_f

Where

M_f = the number of modules in the current release.

F_a = the number of modules in current release that have been added.

F_c = the number of modules in current release that have been changed.

F_d = the number of modules in 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

Answer: (A) SMI approaches 1

5.  The following three golden rules:

1. Place the user in control.

2. Reduce the user’s memory load.

3. Make the interface consistent are for

A) User satisfaction

b) Good interface design

c) saving system`s resources

d) None of these

Answer: b) Good interface design

Reference: Software Engineering, Pressman, Page 402

These golden rules actually form the basis for a set of user interface design principles that guide this important software design activity.

6. Software safety is a ---------------------- activity that focuses on the identification and assessment of potential hazards that may affect software negatively and cause an entire system to fail.

    a)      Risk mitigation, monitoring, and management

    b)      Software quality assurance

    c)      Software cost estimation

    d)      Defect removal efficiency

Answer: b) software quality assurance
