Topic: Siemens Jan 2008 Paper

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, u can easily answer the paper.

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"); elseexit(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.





Some more questions are not remembered.

Here I am concatenating another mail from my friend.The number of questions from

different areas as mentioned before is not correct.The correct numbers are given

below Sections...

1, 5Q ...x windows

2, 5Q .....MS Windows

3, 7Q.....Databases

4, 20 Q....General

5, 20Q....UNIX/C

6,5Q ....OOPS
