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).
