| Dial-up |
Dial-up pertains to a telephone connection in a system
of many lines shared by many users. A dial-up connection is established
and maintained for a limited time duration. The alternative is a dedicated
connection, which is continuously in place. Dial-up lines are sometimes
called switched lines and dedicated lines are called nonswitched lines.
A dedicated line is often a leased line that is rented from a telephone
company.
A dial-up connection can be initiated manually or automatically by your
computer's modem or other device.
