TECHNICAL TEST QUESTIONS
there will be 45 questions.
15(elec) + 5(netw) + 5(os) + 5(compilers and algos)
+ 5(database and misc.) + 5(datastructures) + 5(c progs).
1.A logic ckt is given and asked to identify the configuration.
2.multi vibrator with nor gates is given
ANS: astable multi sqr wave opt.
3.4 stage ripple counter with delay(f/f) 10msec. How much time it takes
for a state to change.
4.impedence of a parallell resonant circiut at resonance:
5.serial to parellel conversion is done by :
5.if the address bus is 20bits.then the memory space is :
6.filtering can be done with:
7.two progs are given. one satrts counting frm 0 to MAX and the other
stars frm MAX to 0. which one executes fast.
ANS:may be Max to 0.Think of it.
8.problem using three registers.
ANS: register A is multiplied by 11.
9.the config that is worst effected by low CMMR
ANS:Non inverting amplifier.
—- Another 6 questions are there. simple.
1.which is not used for error correction :
ANS :bit stuffing.
2.which of the following is not fctn of datalink layer:
ANS : Encryption.
3.voltage levels of rs232c:
4.which of the following is not used for client/server.
1. which of the following is true.
ANS:the primary key in databases design is very important.
2. ANS : SQL is a Non procedural query language.
3. ANS : Time for insertion is more than time for modification.
1.Data structure used to implement a menu:
ANS :doubly linked circular linked list.
2. some regular expression is given:WaW’.
ANS : may be it is context free grammar.
1.The feature of real time os is:
ANS: fast context switching.
2.ANS:os implements protection with the help of hardware(like virtual
addressing in 386/286 etc).
some small C programs are given asked to tell the function/errors etc.
one of the qstn(last in the paper) is an invalid statement. finish of all these very fast and think about those others. they are simple only.
3.whole logic is given in func s but they are working properly. the main logic is :
printf(“%s”,string); /* func to print */
ANS: hello and some extra characters until uccerence of \0 .
4. in a system integer takes 3bytes and char takes 1byte …….
ANS : sizeof struct smthing is 7 bytes.
It depends on the member.
1.Mr.Deep asks architect of 586/486/386/286 etc. otherwise DS,OS,C,TCP/IP.
2.Mr.Abhik asks about compiler design and TCP/IP.
Suggestions in attempting :
1.attempt easy questions first.
Technical test :
1.Attempt C programs first.
2.Network, os, data structures,compilers etc.
3.Electronics and electrical.
