|Hi Frugal, you really need to provide more details asto exactly to what you want to do. Including answering Jolicloud above.|
You have asked two questions, one in the heading and the other in the message..
To connect your landline line to your pc (if being used for the internet):-
a) if broadband - the line is split between voice *AND* data.
voice is connected to your phone
data connects to a router, which is either connected to your pc directly or by wireless.
If the pc is close to the router, connect directly.
b) if not broadband, the line connects to a modem which then is connected to the pc.
The line can be used for voice *OR* data
I prefer an internal modem as this means less boxes and cables.
The modem dials a number to connect to the ISP.
Alternatively the phone can be used normally when the modem is not in use.
Normally modems and routers come with their own installation cd. If from the ISP there will be a walk through on how to connect to them.
Skype is good for using as an internet phone service. Depending on connection, os or pc, this might only provide voice, otherwise includes video. Depending who you are calling it can be *FREE*!
e.g. you are in TIbet, with a broadband internet connection and can talk and see your Mum and Family in Australia at no extra cost other than for the broadband.
You must research what is available at your location and is best for you.
e.g. my broadband service includes all calls (on the voice connection) nationally and internationally to 36 countries 24/7, and to some mobiles in the price.
Hope this helps.
Good Luck - Keep us posted.
