- how much can you afford? But if you're running a mail or a web

technology types include analog modem, ISDN, xDSL, T1, etc. Each
of these technologies have their advantages and disadvantages. Some
technologies might be available in certain areas, but not in other

or switched connections:
there are 2 forms of connectivity - dedicated connections and switched
that are permanently connected to the Internet we call dedicated
connections. Connections that are sometimes connected to the
Internet we call switched connections. A T1 connection is an example
of a dedicated connection. A dialup modem is an example of a switched
