Although most Web authors are familiar with the acronym URL, which stands for uniform resource locator, the term URI isn't as common. URI stands for uniform resource identifier. The primary difference is that whereas a URL must point to a resource on the Web, a URI does not have this restriction. However, URIs must be unique. An analogy would be the word "heaven." It may or may not have a physical location, but either way it describes a unique concept.
