   Hi,
   NUmber Mapping (ENUM), also refers to "Telephone Number Mapping", is a proposed technology for mapping telephone numbers to the Domain Name System (DNS). ENUM includes a suite of protocols to unify the telephone system with the Internet by using E.164 addresses with DDDS and DNS. ENUM is a DNS-based protocol that is best suited to offer services that not only help facilitate, but expand on ways to complete calls over VoIP networks. It provides a user with a domain name on an E.164 server in order to associate a common international telephone number with a URI and provide other DNS-related services. The server is maintained by the Service Provider and is expected to become standard since it can successfully address locating URIs with nothing more than a common international telephone number.

   What Is Data Communications?
   
   
   Data communications is a specialized subset of telecommunications that refers to electronic collecting, processing, and distributing of data between computer system devices. This definition excludes the transmission of data to local peripherals such as disk, tape, and printers.
   Data communications is sometimes called networking because it involves the transmission of data over a network.
