Key Points

In Boolean Logic, conjunctive normal form or CNF means the product of sums ( POS ) which clearly states that it is a product of clauses which in turn are the sum of literals.

For Example,

Y = (A + B) (A' + B)

Y is in the form of Conjunctive Normal Form. It is a product of (A + B) and (A' + B) which are Sums of A and B, A' and B.
