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.

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.

3G (WWAN or 'Wireless Wide-Area Network')

A 3G 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 3G features, check with your service provider to see if any additional charges will be incurred, especially
roaming charges.

Network connections

A LAN (Local Area Network) is a group of computers (for example, within an office building or home) that share a common
communications line and resources. When you set up a network, you can share files, peripheral devices (such as a printer) and
an Internet connection. You can set up a LAN using wired technologies (such as Ethernet) or wireless technologies (such as
WiFi or Bluetooth).

Wireless networks

A wireless LAN or WLAN is a wireless local area network, which may link two or more computers without using wires. Setting up a wireless
network is easy and allows you to share files, peripheral devices and an Internet connection.

Note: More detailed information is available in the InfoCentre wireless networks tutorial.

What are Benefits of a Wireless Network?

Mobility

Wireless LAN systems allow you and other users of your home network to share access to files and devices connected to the
network, for example a printer or scanner.
Also you can share an internet connection with other computers in your home.
