It is not at all the same definition. A CDN is not a programming language library, which is how I had defined frameworks (with other qualifiers). All frameworks are (one or more) libraries in a programming language. A CDN is, ultimately, a network of running servers that serve up content. It's a distribution mechanism for content, not a method of building software applications (which is what frameworks are). You can use a CDN to deliver the code for a framework/library to a web browser (or anywhere else, really), but that is not the same as saying that it is a framework itself, because it is not.
A bunch of people in this thread, including myself, have been trying to help answer your original question (part of which is clarifying terms, since you seem to be confused about how things work, which is understandable for someone inexperienced), and yet you've been very combative and lashing out at people in spite of describing yourself as an amateur. When experts in the field correct your misunderstandings, it's wise to learn from the information you're given rather than telling everyone that they are wrong. Your attitude will not get you very far and will simply make people unwilling to help you learn.
