The Internet is a global
network, connecting many smaller individual networks. For example, a computer
in your room is connected to another computer on campus. All the departments
on campus are then connected to a larger network in the state. The statewide
network is connected to regional, national and international networks.
The Internet is also
a set of "protocols" that allow you to communicate with people, move files
between computers, and find and share information. The protocols you are
likely to use are:
-
email - for communicating
with people across the Internet
-
http - (hypertext
transfer protocol) for making Web pages accessible
-
telnet - for
logging into other computers such as databases and host computers
-
ftp - (file transfer
protocol) for transferring files from one computer to another across the
Internet
