locate Web sites and individual pages.
• They use domain name addressing.
• A domain name is a unique name associated with a
specific IP address by a program that runs on an
Internet host computer.
• This program, which coordinates the IP addresses
and domain names for all computers attached to it, is
called DNS (Domain Name System ) software.
• The host computer that runs this software is called a
domain name server.

Web resources.

that defines how one computer can communicate
and exchange data with another computer on the
Internet.
• Internet protocol (IP) – Defines the Internet’s
