The Internet

Let's start by putting the Internet & Web into proper context.

First, the Internet has many components in addition to the Web. It has Email. It has File Transfer. It has Newsgroups. It has...well, you get the idea!

Each computer on the Internet has one of two roles to play (some do both!):

1. Server Computers: Computers that provide services to other machines, such as hosting web pages, delivering email, allowing for dialup or network connections, and so forth. Examples include the computers for Yahoo!, AOL, and the server that handles your connection to a local Internet Service Provider.
   
   
2. Client Computers: Computers that make requests of Servers. An example would be your computer.

Both Servers and Clients on the Internet can communicate with each other because, regardless of the type of computer (Microsoft Windows, MacIntosh, UNIX, etc.), they all use the same language to connect: the Internet Protocol.
