Page
A page is often used to present “static” information about yourself or your site. A good example of a page is information you would place on an About Page. A page should not be confused with time-oriented content, which is called posts. Pages are typically “timeless” in nature and live “outside” your blog.
The word “page” has long been used to describe any HTML document on the web. In WordPress, however, “Page” refers to a specific type of content that is not time-oriented.
