What the difference between a URI and URL?$$

URI stands for uniform resource identifier and URL stands for uniform resource locator. A URI can be a name, locator, or both for an online resource where a URL is just the locator. URLs are a subset of URIs. That means all URLs are URIs$$

They are the same thing.$$No difference.$$

A URL is a superset of a URI

A URI is a location while a URL is a resource.$$
