Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
Stackexchange is a forum. Because of all those traditional internet fora, some might think that a forum consists of threads, replies and private messages, but that's not nearly the only possible format. A forum is any place/website where people can convene for discussions about certain topics.
