Internet Addresses have several parts

The first part of the address indicates how you access the information:

http - HyperText Transfer Protocol - use a web browser

ftp - File Transfer Protocol - use a program for downloading files

news - Net News Transport Protocol - use a program to read newsgroups

mailto - Simple Mail Transport Protocol - use an email program

The second part of the address, sometimes called the domain name, indicates the name of the computer providing the information (e.g., pbs.org)

The word after the last dot is the top-level domain. There are several major types of domains:

org - organization, usually nonprofit - pbs.org

com - commercial - apple.com

edu - educational - harvard.edu

gov - government - whitehouse.gov

net - network - earthlink.net

mil - military - hanscom.af.mil

There are also domain names based on country:

louvre.fr

Information after the domain name may indicate a specific file or it may describe how information is organized on the computer:

http://www.pbs.org/wgbh/nova/ - indicates an area of the computer with information about NOVA, a program produced by WGBH.

http://www.pbs.org/wgbh/nova/everest/ - indicates an area of the computer with information on a NOVA program about Mount Everest.

http://www.pbs.org/wgbh/nova/everest/climb/indexsouth.html - the end of the address shows the file name that produces the web site you see on the screen.
