I want to learn more about the different types of questions that can be asked on a question and answer site.

Great!  Let’s start with some basic definitions. A “question” is a statement or request for information, and an “answer” is a response to a question. Questions and answers are often called “posts”, because they are usually displayed in a list on a website. There are many types of posts on Q&A sites, including questions, answers, comments, polls, and discussions.
