Connection types
Depending on your computer model, your location and your communication
needs, you have several ways to connect to the Internet.
Dial-up
Some computers include a telephone dial-up (‘modem’) connector. This
allows you to connect to the Internet using your telephone line. With a dial-
up connection, you cannot use the modem and the telephone
simultaneously on a single phone line. This type of connection is
recommended only if you have limited use of the Internet as the
connection speed is low and connection time is typically charged per hour.
DSL (e.g. ADSL)
DSL (Digital Subscriber Line) is an ‘always-on’ connection that runs over
the phone line. As DSL and phone do not use the same frequencies, you
can use your telephone at the same time you are connected to the Internet
(this requires a ‘micro-filter’ on each telephone socket to avoid
interference). To be eligible for DSL, you must be located near an DSL-
equipped phone exchange (service is sometimes unavailable in rural
areas). Connection speeds vary depending on your location, but DSL
generally provides very fast and reliable Internet connection. As the
connection is always-on, it is generally charged at fixed monthly rates.
Note: A DSL connection requires an appropriate modem. A modem is
usually provided by the ISP when you register. Many of these modems
include an ‘router’ that provides network and wi-fi access.
