A URI (Uniform Resource Identifier) is an alphanumeric string that identifies a resource in a computer system; often on the Internet. A URI is comprised of several parts, with the scheme defining the purpose of the URI.
A URL (http://gototags.com) is a type of URI whose scheme is http or https.
There are many different schemes used in URIs, and a handful of very common ones:
- http (website)
- https (secure website)
- ftp (file transfer protocol)
- file (local file)
