There are several other types of URI, though URLs are the best known.

Yes. URNs and URCs, for example. The CNRI handle system and the Xanadu
addressing system are examples of URNs.
URLs describe how to locate a specific resource.
URNs describe a specific resource without defining any specific location.
URCs describe metadata about a specific resource.
For more information, RTFM (the RFCs or the W3C website).
