Some questions from excel book. (1 Viewer)

[-X-]

Can someone please explain to me these questions and how they got the answer?

1 Which of the following includes only examples of intrinsic documentation?
A Balloon help, use of meaningful variable names
B Header block, appropiate commments within the code.
C read me files of instructions, meaningful names for identifiers.
D listing of the source code, indentation to show control structures.

Answer to this is B (acording to excel), but doesn't "intrinsic" mean indentation/layout of code? And "internal documentation" meaning commenting/meaningfull variable names etc... Im kind of leaning towards D for this one.

When analysing a system it is often helpful to break the system into smaller subsystems. What id this process called?
A bottom up design
B Determine the bounday of the system
C Synthesis
D Refinement

Answer is D again but shouldn't it be A?

and last question...

When representing a systenm the best method to show levels of refinement of a process would be to use:
A IPO chart
B structure diagram
C DFD
D Object Chart

I have no idea what this question means? The answer to this is B.


Thanks in advance

1: You are back to front. The answer should be B because Intrinsic is your meaningful variable names/comments etc. There's another thread on this.
Can't be A because Balloon Help is Internal Help, not intrinsic.
Can't be C because read me files are not either.
Can't be D because whilst Indenting might be intrinsic - listing of source code means nothing, and is irrelevant.

2: The question says when ANALYSING a system. That would hint that you aren't designing it, but looking at an existing system (or maybe stats for a new/rebuilt system)
You probably just have to recognise syllabus terms also here:
B and C are way out, so its out of A and D.
D is the term the syllabus uses for analysing a system in this way, so I'd go with that.

3: If you didn't know what refinement was in the last question, then this one will be equally confusing.
When 'representing' a system (like - using diagrams or charts).
Showing levels of refinement (showing the steps in which the system is broken down into smaller modules.)
Answers:
D is out - there's no such thing in our course.
A is out, because it doesnt show any form of refinement.
Whilst D and C both show some form of refinement (ie representing the system in smaller modules), only one of these does it in LEVELS - and that is B - Structure Diagram.

Ok according to the other thread:

Internal = intrinsic + commenting.
Intrinsic = Meaningfull variable names, indentation etc...

So "B" says "...commenting...", but commenting is internal documentation and not intrinsic?

Thanks for your reply, i understand the other 2 now.

 

[:: ck ::]

read the question for 2

(A) is the diagram
(D) is the application

therefore must be D

Intrinsic includes commenting, anything that relates to the actual code in intrinsic (var names - commenting - indenting..)

Intrinsic documentation is a sub category of internal documentation from what I gather.
