Paper : TCS Placement Paper Pattern (Technical)

Hi,he started with component object model which is my paper presentation it starts like this.

 1. what is com?
 2. how is it different from class in c++.
 3. how does com satisfies encapsulation?
 4. how is com called? how it is different from c++?
 5. what are synchornization techniques in os?
( I KEPT SILENT THEN HE ASKED ABOUT SEMAPHORES,CRITICAL SECTION, MUTUAL EXCLUSION THEN I ANSWERED ABT THEM. THEN HE TOLD THEY ARE NOTHING BUT SYNCHORNIZATION TECHNIQUES>

 6. he asked bankers algorithm? and what is its necessary?
 7.what are the other conditions to avoid deadlock?
 8. what is tcp/ip?
 9. compare the layers of tcp with osi. he told me to draw it i did it
 10. what is a datagram?
 11 what is a dirty bit?
 12 what is the difference between macro and inline funciton?
 13.what is a friend function?(he asked two to three question on this topic)
 14. he gave a code and told to find the value which i did it.
 15 he asked reg socked programming?
(i told that we are concerned with the theorital concepts and we are not aware of programming knowledge. this is the biggest mistake i have done so better avoid tcp/ip in areas of interests)

 16 he asked what is the necessity of program id in cobol?
 17 he asked to rate up in c++ in 1 to 10 scale.
