URI (Uniform Resource Identifier) vs URL (Uniform Resource Locator)

by Juan

.	URI	URL
Scope	Can be used outside of internet	Use for internet only HTTP, HTTPS, or FTP
Examples	urn:isbn:0-302-38006-X (identifies a book by its ISBN) mailto:[email protected] (identifies an email address) file:///path/to/file.txt (identifies a local file)	ftp://ftp.example.com/public/file.zip (file download location)

All URLs are URIs, but not all URIs are URLs.
