This is an example of a WordPress page.
Pages are an idea both WordPress and TypePad embraced as a way to allow people to use their blogging tool to create web sites as well.
Because blogs were so much easier to maange and accessible to people without needing to understand code they became a great way to build a site that serves the needs of most web site owners.
When you “post” or add a content in a post in WordPress, it shows up on your blog, newest at the top. Many posts can show up in one page in a variety of ways, just the titles, titles and an excerpt with a link to the full post, or the full posts. Post titles show up, usually in your sidebar and usually archived by month or with the a list of the most recent posts, or both.
Pages are stand alone pages, as the name implies. When you create a page, the name is added to a navigation bar automatically. Usually this menu is at the top of your blog, depending on the style you choose.
You could have only pages and create a traditional web site.
Or you can have just posts and create a blog.
Or you can have both as does this demonstration site.
Normally you allow comments on posts but not on pages because they tend to be informational rather than social.
