There were
2 sets : software 'n hardware. software paper had 3 sections:
Section I – General Aptitude – 10 questions

Section II – System Concepts – 20 Questions

Section III – Programming Skills – C,C++, RDBMS – 20 Questions

in hardware paper, instead of programming section, digital was asked
...i suppose.vlsi was also asked.

SOFTWARE PAPER:

Section I – General Aptitude

1. Four persons picking balls. Peter one more than paul. Pam one more than

many of the qns were frm paging..sry, i don't know the subject. i don
remember most of the qns.

1. 8085 architecture:

a) Risc b) Cisc c) both d) neither

2. Memory space depends on

a) no. of address pins b) no. of data pins c) ALU

3. Which is context free language?

4. hit ratio calculation in OS?

5. 2 frames

Time page

1 some value

2 ,,

3 ,,

4 ,,

5 ,,

6 stop

what are the two pages in the frames when replacement method is used?

6. What is Zombie Prosess?

SECTION 3. PROGRAMMING

questions on loops in C, Data stuctures and RDBMS were asked.

some qns i remember:

1. which is better? 1st or 2nd or 3rd normal form or Boyce codd normal
form?

2. which is not a command in sql? drop, delete, create, insert.?

3. Class A

{

fn to print ‘A’;

}

Class B {virtual fn to print ‘B’ }

Class C {fn to print ‘C’}

a ptr object is created for class C, what will be printed? juz check out
that virtual fns concept in C++

4. Efficiency of sorting bubble, merge & memory efficiency for both best &
worst case?

5. which is memory inefficient? Quick, merge, bubble.

6. worst case for merge sorting? n log n, n2, n-1

7. which is correct or which will swap nos.. i think this is the qns..one
of
the choices were.:

a^=b^=a^=b (in C)

8. i= 20;

j= 50;

printf(“%d”, sizeof(i+j));

9. which takes less time to execute.? ordinary functions or recursive funs.
i think its recursive since stack winding and unwinding is there.

10.how much memory will be allocated to this union:

union a

{

char b;

int no:2; (bit field)

}

11. what is the argc value?

C:\ sample.exe val1 val2 val3

ans: 4

12. one qn about ptr to funciton :

how will a ptr to a ptr to a fun will be declared

void *(*ptr[]));

void *ptr[];

void (**ptr[]

.( this is wrong, the qn was of this type.. i remember only that. read the
concept well)
