1.General
2.Unix and c
3.RDBMS
4.C++/object oriented
TCP/IP
RDBMS-----
1.What is RDBMS...Def
2.Two tables are given.In 1st table 2 columns are there.one
isEmployee no,second is salary.In second table 3 columns are there,one is employee
no,second is date,3rd is salary.
Select employee no,from table1,table 2.
How many records it will contain?.(This is somewhat difficult).
3.What is transaction?
TCP/IP:
1.X.25 protocol belongs to which layer.
2,Order all the 7 layers in sequence
3,One node has 2 IP address but data goes through only one link.What is the reason?
4,Router,Bridge,Gateway....Which one of these can not connect
two different LANS and is protocol sensitive.
5,Client sends server---reqest or demand or -----Choices are given.
1.main(argc,argv)
{ if(argc<1) printf("error"); else exit(0); }
If this program is compiled without giving any argument ,what it will print.
2.What are the static variables...def
3.What is Dynamic allocation ?
4.Dead lock condition...What may be the condition for it.
5.Semaphore variable?..def
6.Most of the Windows operating systems are....choices are given like
----a,maltitasking,multiuser,multi processing
b,only.......&......
c,only........&......
like that
7.Properties of object oriented,(just recall the name of the properties like
inheritance,....
8.A program of C++,and two questions were based on the o/p of that program.\
1, 5Q ...x windows
2, 5Q .....MS Windows
3, 7Q.....Databases
4, 20 Q....General
5, 20Q....UNIX/C
6,5Q ....OOPS
Some questions.....
1,Sticky bit concept
2,Bourne shell.,no hup concept
3,Net work layers
4,Ethernet,Token Ring Unix...(Ans is Multitasking,Multi user)
6,Windows...(ans is pseudo multitasking)
7,IP Addresses
8,Normalisation(in data basese)
9,SQL Queries
10, semaphores
