Match the following:

$$\begin{array}{|ll|ll|} \hline \text{a.} & \text{Size-oriented} &i. & \text{uses number of external interfaces as one of} \\ &\text{metrics}&& \text{the measurement parameters} \\ \hline \text{b.} & \text{Function-oriented} &ii. & \text{originally designed to be applied to} \\ & \text{metrics} && \text{business information systems} \\ \hline \text{c.} & \text{Extended function} &iii.& \text{derived by normalizing quality and/or productivity} \\ & \text{point metrics} &&  \text{measures by considering the size of the software} \\ \hline \text{d.} & \text{Function point} &iv. & \text{uses algorithm characteristics as one of} \\ & && \text{the measurement parameter} \\ \hline \end{array}$$

  1. $a-iii, b-iv, c-i, d-ii$
  2. $a-ii, b-i, c-iv, d-iii$
  3. $a-iv, b-ii, c-iii, d-i$
  4. $a-iii, b-i, c-iv, d-ii$

Ans is D

a-iii    is directly implied

b-i    function oriented metrics measuring the following parameters:-

•Number of user inputs:
Each user input that provides distinct application oriented data to the software is counted. 

•Number of user outputs:
Each user output that provides application oriented information to the user is counted. In this context output refers to reports, screens, error messages, etc. 

•Number of user inquiries:
An inquiry is defined as an on-line input that
Results in the generation of some immediate software response in the form of an on-line output. Each distinct inquiry is counted.

•Number of files:
Each logical master file (i.e., a logical grouping of data that may be one part of a large database or a separate file) is counted.

•Number of external interfaces:
All machine readable interfaces (e.g., data files on storage media) that are used to transmit information to another system.

c-iv A function point extension called feature points, is a superset of the function point measure that can be applied to systems and engineering software applications.The feature point measure accommodates applications in which algorithmic complexity is high. Real-time, process control and embedded software applications tend to have high algorithmic complexity and are therefore amenable to the feature point.

d-ii   function point is a "unit of measurement" to express the amount of business functionality an information system (as a product) provides to a user. Function points are used to compute a functional size measurement (FSM) of software. The cost (in dollars or hours) of a single unit is calculated from past projects.[1]
