Overview of the Internet
The Internet is a network of networks, all agreeing to speak to each other in
a common language (protocol). Each network consists of many individual computers,
called hosts or nodes, connected together with some sort of cables to form a network.
Each host might handle one or more type of activity, or application. The most well
known applications that run on the Internet are:
- E-mail
- World Wide Web (WWW)
- Other parts of the Internet:
- File Transfer Protocol (FTP)
- Usenet Newsgroups
- Internet Relay Chat (IRC)
New applications for use over the Internet are being developed all the time.
This list is just a small sampling of the types of applications that the Internet
currently has on offer.
