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.

You can use your telephone and watch cable TV at the same time you

are connected to the internet.

Cellular

A cellular connection allows you to use cellular networks (such as

those used by a mobile phone) to connect to the internet while away

from home. The socket for a SIM card may be built in to your

computer, or may require an external device, such as a USB modem

or even an appropriately equipped mobile phone.

Note

If your computer includes a SIM card slot, you require a compatible SIM card

and a contract with a cellular provider.

Before using the cellular features, check with your service provider to see if

any additional charges will be incurred, especially roaming charges.
