- Modems and routers
- Negotiating a connection
To connect from home you need several things. Apart from a computer, you'll need a phone connection, a modem or ADSL router, and some Internet software. Things will be easier if you're using a relatively recent operation system, such as Windows Vista/XP or MacOSX, but it's possible to connect with older or more obscure systems.
With a modem and the appropriate software, you can dial up another modem connected to another computer, and establish a network connection with it. Usually, this computer is linked into the Internet, and so you're online.
With an ADSL modem or router, a similar procedure happens, but a filter splits the telephone line into-voice and data (low and high frequencies) and your router negotiates a connection with the ADSL equipment in the telephone exchange.
