1) I took few answers from Google, if I post all those here that is violation of copy rights.
2) If I give answers too, everyone do copy and paste but during this we can't improve our knowledge. Better to search in Google, read total paragraph when you search the topic and then took useful information alone then only you can able to understand the concept properly.


Conclusion:



Before attend the interview you just check with by yourself do you know all the above questions answers or not. If you said I'm not worked in that particular domain then they won't accept that, if you are not worked also they are expecting minimum background knowledge in that. In sometimes they are expecting definitions too, if you are explain that in practically they won't accept that.
