Quick answer? Are we in the middle of a test?

Pretty straightforward if you think about it.
What kind of gate does XNOR represent ?

for 3 input variables, xnor logic is 'even function of 0's'.. and in some books it is written 'even func. Of 1's'.. don't know why is that so? Any explanation please :-|

XNOR is the opposite of XOR gate.
Have a read of this: XNOR gate - Wikitronics (http://electronics.wikia.com/wiki/XNOR_gate)
Sufficed to say XNOR with 3+ inputs behaves erratically.

Means both logics I've given can be correct?
