Siemens Placement Papers and Sample Papers

THIS PAPER CONSISTS 6 PARTS. all are multiple choice q's
1)general
2)c/unix
3)c++/motif
4)database
5)x-windows
6)ms-windows
we have written q's not acc. to each part.total 50. q's. time is
sufficient.
if u have basic idea about all of the u can easily answer the paper.

d)none
20)struct {

abc.x;
(abc)-- x;
a)1,2,3
b)2&3
c)1&2
d)1,3,4

BEST OF LUCK

This is sisl paper given in iit kanpur. enjoy this.

All are multiple choice questions.60 questions to be answered in 60 mins.
Distribution of questions:
---10 questions from data structures and some general topics.
-----10 questions from Unix and C.
--7Questions from Data base.
----Remaining from Windows(x windows,MS Windows etc..)
The distribution is not exact.Only approximate.
Totally there are six sections as below:
1.General
2.Unix and c
3.RDBMS
4.C++/object oriented
TCP/IP
6not remembered.
The questions are as follows:
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.
Another section...
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
