Question 1

The coupling between different modules of a software is categorized as follows:
I. Content coupling
II. Common coupling
III. Control coupling
IV. Stamp coupling
V. Data coupling
Coupling between modules can be ranked in the order of strongest (least desirable) to weakest (most desirable) as follows:

• AI-II-III-IV-V
• BV-IV-III-II-I
• CI-III-V-II-IV
• DIV-II-V-III-I

Question 2

The Function Point (FP) calculated for software projects are often used to obtain an estimate of Lines of Code (LOC) required for that project. Which of the following statements is FALSE in this?

• AThe relationship between FP and LOC depends on the programming language used to implement the software.
• BLOC requirement for an assembly language implementation will be more for a given FP value, than LOC for implementation in COBOL.
• COn an average, one LOC of C++ provides approximately 1.6 times the functionality of a single LOC of FORTRAN
• DFP and LOC are not related to each other

Question 3

The availability of complex software is 90%. Is Mean Time Between Fallure (MTBF) is 200 days. Because of the critical nature of the usage, the organization deploying the software, further enhanced it to obtain an availability of 95%. In the process, the Mean Time TO Repair (MTTR) increased by 5 days.
What is the MTBF of the enhanced software? (Choose the nearest option)

• A205 days
• B300 days
• C500 days
• D700 days

Question 4

A company needs to develop a strategy for software product development for which it has a choice of two programming languages L1 and L2. The number of Lines Of Code (LOC) developed using L2 is estimated to be twice the LOC developed with L1. The product will have to be maintained for five years. Various parameters for the company are given in the table below:

Total cost of the project includes cost of development and maintenance. What is the LOC for L1 for which the cost of the project using L1 is equal to the cost of the project using L2?

• A4000
• B5000
• C4333
• D4667

Question 5

A company needs to develop digital signal processing software for one of its newest inventions. The software is expected to have 40000 lines of code. The company needs to determine the effort in person-months needed to develop this software using the basic COCOMO model. The multiplicative factor for this model is given as 2.8 for the software development on embedded systems, while the exponentiation factor is given as 1.20. What is the estimated effort in person-months?
