What is the difference between a class library and a framework

Question

I hear the whole day the terms class library, base class library, Framework, ...
What highlights a framework and what a base class library?

Answer 1

The distinguishing feature between a class library and a software framework is that in a framework, the flow of control is not determined by the user′s code, but by the framework.

This is also known as Hollywood principle (don′t call us, we call you).

By the way, there is also a nice Wikipedia article on this topic.
