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.
Cable
A cable connection provides fast and always-on Internet service via a
cable television line. This service is generally available in large cities.
