CSC PAPER ON 14th JULY 2006 AT CSC NOIDA

in written thy giv two tests:-
1) quant/aptitude/logical ppr 40ques in 40minutes
2) technical test 75question in 40min
apti/quant/logical
it was a very tough test i hav given test of 6-7 companies but csc test was toughest
ther vr linear equations questions wich vr not at all easy
questions on sets
-permutaion combination
-arrangement logical ques
- distance speed ques
- time question

APTITUDE/QUANT/LOGICAL TEST QUESTIONS
-ques like 90% of 1 litree milk and 60% of 40 litre water result in 67% mixture so wht is compostion of milk in litres?
-ques like f has pririty over h and g has priortiy over i so now 4-5 ques based on this

-length is increased by 5 and breadth is decreased ny 10 thn total is 200m and whn length decreasd by 5 and breadth increasd by 15 thn total is 75 m, fing length

-a>b>c so wich is tru
ab>ac or a/b>b/c or som more options

-6 girls and 6 boys, all boys and all girls will sit together so no of possible ways

- cow is tied with rope from two sides 40 40 cm and forming an angle 24degree size of rope is 15cm so how much area in wich cow can graze

-7 orange and 5 apples cost 16.90 rs and 5 oranges and 7 apples cost 2.60 so no of oranges

-ther is a place wher ppl r either no or yes. if ram sain 2and 2 makes four thn he is yes and similarly if mohan said 2 -1 is 2 thn he is no. so now ques based on this

- paragraph given and u hav to conlude or find contradicting line

and rest all questions vr very tough so i dont remember thm at all


technical ques
-os
-dbms
-ds
-n/w
-microprocessor(806139...)
-java
-c c++


TECHNICAL WRITTEN TEST QUESTIONS
- wht is piggybanking used for (acknowledgement)

- wht combines router and bridge
(hub/brouter)

- tcp/ip is wht conection oriented or conectionless

- X.25 protcol is at wich layer

- wht is superkey (primarykey+attribute)

- wich join will u use to hav null values (outer)

- query was given find join type
select customer.is and order.is and name from customer, order
where cutomer.id= order.id (natural join)

- wich follow binary tree property

- som code of java given find no of dangling pointers

- linked list a->b and b pt to itself so wht type of linked list (infinite)

- which line is wrong abt linked list
(circular list can be only implemented in doubly linked list)

- os question on context switch and sytem call

- microporcesor ques like result of 2 input , 1 o/p line and three annd gates is (nand)

- which gate need to combine with or gate to make nand gate

- transfer RO to local and local to RO and shift RO 3 timed thn local to RO so result is
(RO=local)

- some instruction were given and u hav to find resultanf values of flags

- some instrcution was given find output shift 2 times right to 80008ff

- atomicity definiton was given and u hav to tell wich property it is(atomicity)

- questions vr given fill in the balnks three places (placemnt,replacemnt,replacment) order was correct

- wich normal from shld be saticsy to hav bcnf and one more condition was given

- som ques of physics given resistance and volts use so u hav to tell output (low voltage or high voltage or??)

- wich sort take o(n^2) time
quicksort

- some prog given outer fro loop from 1 to n and inner frm 1 to k so time is
O(nk)

-right output of preorder traversal som tree was given

- wht r abstract data types

CSC PAPER ON 14th JULY 2006 AT NOIDA

NETWORKS
1) whn u open web browser, thn wht will happen wht do u do first thing?
2) wht u write first thing, i said DNS or webaddress concept thtn he asked complete web adress like i told
http//:www.orkut.com
thn he asked meaning of each word-http,www,com etc
3) wht is URL
4) tel complete procedure how a site open after opening explorer
5) other layers understand DNS or not if not thn wht will happen (concept of mapping to ip adress comes here) thy asked how mapping takes place and at wich layer
6) dns procedure use wht tcp/ip or osi
7) how many layers in tcp/ip and wich layers are extra in osi model
8) tcp/ip conection oriented or conectionless
9) wht is DNs he was trying to ask in detail but as i havnot read so i said tht
10) wht is arp
11) wht is rarp
12) wht is ATM(asynchronous mode transfer)


DBMS
1) wht is primary key
2) if ther is no primary key how will u uniquely identify each tuple (i said composite key or super key)
3) diff between tuple and attribute
4) wht r anomalies explain each in detail (like insertion anomaly deletion and modification anomaly)
5) wht is foreign key constraint
6) if i want to delete a tuple from a table having reference in so other table thn wht will happen (concept of cascade comes else error)
7) wht r triggers explain
8) if i want to hav som tuples havind null value wht to do (outer join)
9) wht if i join two tables and no primary key (spurious tuples generate redundant data)
10) he asked me wht will u do if need to retrieve this so basically query
and select first four tuples
select *
from employee
where salary
thn apply rownum<=4 to select first four tuples
11) diff betweenoracle 9i and oracle 8
12) diff between dbms, rdbms, ordbms



OS
1) wht is os
2) wht is a process
3) diff between process and thread
4) if threads share data section wht will happen
(concept of semaphore and crtitcal section comes so )
5) wht is semaphore
6) wht other thing semaphore do except synchronisation
7) wht else happen in threads and process so deadlock concept comes
8) deadlocks, and i told abt 4 conditons of deadlocks also
9) in os wher do u use stacks and queues
(like stacks for saving process satate , on system call context switch etc and queue in scheduling so he asked do we hav only fifo scheduling)
10) so types of scheduling



Data Structure
1) u hav fifteen boxes in kitchen and ur mom asked u to make foos for 1 month, wht will u do to make food fast (thn concept of sorting came)
i said i will put name tag on boxes and thn sort thm in ascending order or i can put thm in order of color shade firstly lightest and thn little darker and soon but tht can create confusion so first is better way
2)u hav 1000 names in unorder manner and i asked u to pick any name of my choice randomly and thn giv me complete info of tht person so wht ds will u use
i said firstly i will sort thm thn i will use hashing/btrees as thy r faster in decreasing search domain,
thy asked wich sort will u use
i said radix as good for strings , he asked if one more name increase or decrease i said radix sort take linear time so doesnot affect much on time
he said if names r vary in length like one is venkateshraman other is raj i said sort from 3rd last letter or use padding.
3) wht is heapsort, concept . wher u can apply it
4) wht all ds u know
i said heaps binomial fiboncaai, liked list stacks queues trees arrays etc
5) advantage and disadvantage of linked list and array over each other in temrs of memory allocation
6) insert and delete a node in a linked list write a code(not from me)

basically thy asked asll application based question on data structure


java/c/c++
1) he write a java code of swapping to name via calling object as parameter and asked whther result will reflect in main or not
(as object passed as a reference so reuslt will be reflected)
2) in java we use call by reference or call by value
3) wht r interfaces
4) diff between interfaces and abstraction


NOTE
- before going for interview i hav heard tht thy ask ur fav subject note tht and thn asked ques accordingly but today thy start taking interview without asking any fav subjects from all of us
- so be prpeared for DBMS, os, ds, java, networks and c/c++(little bit)
- n/w questions vr all concept based no theory thy just want to see how things happen
-either u'll go offcampus or oncampus thy take 35 minutes to 1 hr interview of each person). mine was 35 minutes so u can see no of ques asked think abt my frnd whose interview was of complete 1 hr even whn we vr oncampus
