It's a good thing that you've actually understood the concept. As for an exact definition, if you look at 5 different texts their definitions of these concepts will differ somewhat. But the concept still stays the same.

Whats a class?
A. Its can be thought of as a user defined data type.A class defines the structure and behaviour which is shared by a set of objects.
Whats an object?
A. Its an instance of the class
well it can now be usderstood that the class is a logical construct; an object has a physical reality.

Class can be thought of as template, and objects are derived from that template. When objects are created memory is allocated to that object so that it could be further used.
