What is URI? Can anybody help me What is URI please?

Pierre Sirolli

A URI can be further classified as a locator, a name, or both. The
term "Uniform Resource Locator" (URL) refers to the subset of URI
that identify resources via a representation of their primary access
mechanism (e.g., their network "location"), rather than identifying
the resource by name or by some other attribute(s) of that resource.
The term "Uniform Resource Name" (URN) refers to the subset of URI
that are required to remain globally unique and persistent even when
the resource ceases to exist or becomes unavailable.
The following examples illustrate URI that are in common use.
-- ftp scheme for File Transfer Protocol services

-- gopher scheme for Gopher and Gopher+ Protocol services

-- http scheme for Hypertext Transfer Protocol services

-- mailto scheme for electronic mail addresses
-- news scheme for USENET news groups and articles telnet://melvyl.ucop.edu/ -- telnet scheme for interactive services via the TELNET Protocol
