About the Internet
How information is transmitted over the Internet
118
exchanges (MAEs). There are regional highways provided by large ISPs
and local streets provided by local ISPs.
Like a system of roads and highways, the Internet provides multiple routes
from one point to another. If one part of the Internet has too much traffic, or
is damaged, information is rerouted.
How information is transmitted over the Internet
All information sent over the Internet is communicated using a protocol
called TCP/IP. Because all of the computers on the Internet understand this
protocol, each one can communicate with every other computer on the
Internet. TCP and IP are separate parts of this protocol.
