PART --A
-------------------------------------------------------
1) abcD+abcd+aBCd+aBCD
then the simplified function is
( Capital letters are copliments of corresponding letters
A=compliment of a)
[a] a [b] ab [c] abc [d] a(bc)* [e] mone
(bc)*=compliment of bc
Ans: e
-------------------------------------
2) A 12 address lines maps to the memory of
[a] 1k bytes [b] 0.5k bytes [c] 2k bytes [d] none
Ans: b
-----------------------------------------
3) In a processor these are 120 instructions . Bits needed to impliment
this instructions
[a] 6 [b] 7 [c] 10 [d] none
Ans: b
------------------------------------------
4) In 8085 microprocessor READY signal does.which of the following
is incorrect statements
[a]It is input to the microprocessor
[b] It sequences the instructions
Ans : b
-----------------------------------------
5) Return address will be returned by function to
[a] Pushes to the stack by call
Ans : a
-------------------------------------------
6)
n=7623

-----------------------------------------------
7) If A>B then
F=F(G);
else B>C then
F=G(G);

are there ,then the ratio of F to G
[a] 7500:2500 [b] 7500:625 [c] 7500:625 if a=b=c else
7500:2500
---------------------------------------------------
8) In a compiler there is 36 bit for a word and to store a character 8bits are
needed. IN this to store
a character two words are appended .Then for storing a K characters string,
How many words are needed.
[a] 2k/9 [b] (2k+8)/9 [c] (k+8)/9 [d] 2*(k+8)/9 [e] none
Ans: a
----------------------------------------------------------
9) C program code
int zap(int n)
{
if(n<=1)then zap=1;
else zap=zap(n-3)+zap(n-1);
}
then the call zap(6) gives the values of zap
[a] 8 [b] 9 [c] 6 [d] 12 [e] 15
Ans: b
