  • 1.02 URL's Anatomy The protocol determines how the information will be transferred. FTP is a two-way system in which entire files are copied from the sending server or device into the receiver’s computer. HTTP is used to transfer files from a Web server into a browser on a user’s computer in order to view files from the Internet. The domain name is sort of like your zip + 4 code. The domain name includes the host server , a suffix , and sometimes a country code . Examples of host servers and their extensions: Microsoft.com, ecu.edu, bls.gov, ncsecu.org, bidlink.net, and http://www.nic.mil/ Examples of country extensions include .uk, .au, .ca The Internet is a huge global network of computer networks. The Web is a tool used to access information from the Internet. Browsers are used by the Web to transport data from the Internet to the user. FTP URLs link to files on other servers, but not on the Web.
