There are 20 such questions. Questions are very easy.
Section2 consists of some questions from microprocessor, digital electronics, one question on turing machine (the question was very long) and some questions on C (some what trickybut solvable if enough time is left)
Some questions which I remember are
Find sqrt of 113 upto 3 decimal places.
20 bit address bus can address how much memory
find 2's complement of 111001001

10 to (x) 7
Conver 100011 in decimal
To represent A to Z and 0 to 9 how many bits are required. Assuming all the characters requires equal bits.
210 = Kilo byte
A op B = XXXX00XXXXXX0XXX
Find B and op, where op is a logical operator and X = don't care
To add 16 bits numbers how many full adders and half adders are required.
A full adder has how many input lines.
Find Y
#define count (x) sizeof (x)/sizeof (x[0])
what count (x) does?
X = 24, Y = 16
X^ = Y
Y^ = X
X^ = X
Y^ = X
Find value of X and Y (the exact question may be some what different)
#define inum 53268
While (.) { inum = inum & (inum1); … }
