URI and URL

URI

URI stands for Uniform Resource Identifier. A uniform resource identifier (URI) is a string of characters used to identify a name of a resource.

URL

A uniform resource locator (URL) is a reference to a resource that specifies the location of the resource on a computer network and a mechanism (http, ftp etc.,) for retrieving it. A URL is a specific type of URI.

ftp://ftp.is.co.za/rfc/rfc1808.txt

http://www.ietf.org/rfc/rfc2396.txt

telnet://192.168.2.16:80/

Above all are URL’s, since they had access protocol mechanism like ftp, http, telnet. URI don’t specify the access mechanism.
