No, this is not the same thing as a web page. Though the two terms are often used interchangably, they shouldn't be. So what's the difference? Well, to put it simply, a web site is a collection of web pages. For example, Amazon.com is a web site, but there are millions of web pages that make up the site. However, if you mix up the "web page" and "web site", don't worry, most people could care less.
