File Transfer Protocol - A communications protocol governing the transfer of filesfrom one computer to another over a network.
Computers use IP addresses such as 205.171.9.242 to locate resources on the Internet. However, since people prefer to use simple names to long numbers, a \"human-friendly\" system using fully-qualified domain names was developed. DNS works by resolving fully-qualified domain names, such as www.qwest.net or mail.qwest.net, to a specific IP address. Fully qualified domain names are also referred to as FQDNs.
