i would like to stat THIS topic so that we can share viva questions about the external practical exams

here is an attachment for the software engg practical

and the some of the questions asked by the external examiner in today's practical

1. difference b/w walkthrough and inspection
2. in which model risk analysis is involved
3.difference b/w prototyping and evolutionary model
4.symbols used for use case diagrams
5.difference b/w dfd and sequence diagram
6.what are the symbols used in sequence diagram

sorry at present i remember only this much
if anyone would like to share for other practicals that would be appreciated

some of the Viva Question In DCS Lab were :-

(1) who invented C (language)
(2) Define Software Engineering
(3) write algo to implement 2 bit comparator
(4) Draw the diagram of bread board
(5) Show the Connection to implement a and gate on bread board
(6) How cost estimation is done
(7) convert hexadecimal to binary
(

write your name in ASCII code
(9) write code in c for Or gate
(10) what are K map and why they are used and What are their limitations

and dont think that i am mad really all these questions were asked by the externals

i was just asked the basic principal that is utilised in fm demodulation
my answer
fm->am->envelop detector will give baseband signal
got highest on offer that is 15 marks

The examiner asked which topic you know, and then asked detailed questions from the topic. I was good at UML(both theory and practical). I was asked about:
1. Class Diagrams
2. State Diagrams
3. Draw a state diagram of Hotel management System
4. Activity Diagram and example
5. Different UML diagrams and difference in them.
Some questions my friends were asked:
1. White box, Grey box, Black Box Testing
2. Alpha/beta/Interface/Regression Testing
3. Reverse Engineering
4. SDLC, some or the other was asked to everyone, so all SDLC Models were asked in short!
5. What is Software Engineering
6. What is SRS, why is it used?
