the Internet

The Internet is a global network, connecting many smaller individual networks. For example, a computer you use in the library is connected to another computer on campus. All the departments on campus are then connected to a larger network in the state. The Minnesota 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:

for communicating with people across the Internet
(hypertext transfer protocol) for making Web pages accessible
for logging into other computers such as databases and host computers
(file transfer protocol) for transferring files from one computer to another across the Internet
