Differences between URI URLs

Uri stands for Universal Resource Identifier

URL stands for Universal Resource Locator

The URL is actually a subset of the URI,A URL is a subset of the URI popular protocols. These are protocols (http: //, ftp: //, mailto :)

 

I am a posting machine today! Anyway, for a while now I 've been quite confused about the difference between URLs (Uniform Resource Locators) and Uris (Uniform resource identifiers). I finally decided to do
A little research and try and identify the distinction. I found the following at the W3C's contemporary view of uniform resource identifiers:

"... A URL is a type of URI that identifies a resource via a representation of its primary access mechanisms (e.g ., its network "location"), rather than by some other attributes it may have. thus as we noted,
"Http:" Is a URI scheme. An http uri is a URL. The phrase "URL Scheme" is now used infrequently, usually to refer to some subclass of Uri schemes ..."

however, as is typical with W3C documents and specs, there's a little too much technical mumbo-jumbo floating around in that explanation to satisfy anyone who doesn't balance their checkbook in binary, so
I kept looking. kenth fly's web site provides provided the following:

"URI stands for Universal Resource Identifier and URL stands for Universal Resource Locator. often times people use the terms interchangably, which is not entirely correct. a URL is a subset of the URI popular
protocols. these are protocols (http: //, ftp: //, mailto :). therefore all URLs are Uris. the term URL is deprecated and the more correct term URI is used in technical documentation. all Uris are means to access a resource on the Internet and are a technical
short hand used to link to the resource. uris always designate a method to access the resource and designate the specific resource to be accessed. "

So... My terminology is apparently way out-dated and I need to start saying "Uri" instead of "url." Why? Because anything that has been deprecated is bad news (remember the edevil

<Blink> tag ?). Now I know, and knowing is half the battle.
