13. Which language used by most DBMS to provide data access to its users (query language, SQL, C, )
I also selected SQL but it is wrong! Correct is Query Language.

Because there are lot of DBMS and they provide different Query Languages like:
DMX
ISBL
LINQ
MQL
MDX
OQL
OCL
SQL
SPL

http://en.wikipedia.org/wiki/Query_language

Q10 was about connecting two LAN's (two local area netwroks which are already connected with hub or switch)
Now we will use router to connect two networks.

- There was also a question like, which supports Asynchronous Transmission? (Serial Transmission, Parallel Transmission Both A,B, Multiplexer) what can be the answer?
