enter the internet
Because the Internet is basically a network made up of so many networks, people can send their work out and spread
it out and make other people's computers do it. How about that?
The Internet is essentially a server-client network (see figure 6).
You may have seen Netscape or any other Internet program tell you that it is contacting a "host" or
a "server" — both mean the same thing. That server is the computer you are connecting to.
What makes the Internet powerful is the multitudes of servers, each with different, specialized
jobs: file servers transfer files upon request, mail servers send and receive e-mail messages,
newsgroup servers send and receive newsgroup messages, chat servers transfer Internet relay chat
messages... there are many, many different types of servers. They all give your computer what it
asks for, because they are there to serve your computer, the client.
