List of Official URI schemes

An URI scheme is the top level of the Uniform Resource Identifier (URI) naming structure. All URIs and absolute URI references are formed with a scheme name, followed by a colon character (":"),

URI schemes are frequently erroneously referred to as "protocols", or specifically as URI protocols or URL protocol.
For.e.g The http scheme, for instance, is generally used for interacting with Web resources using Hyper Text Transfer Protocol.
