I have a ps3 but i dont have a computer in my house. Will a internet company be able to install internet straight to the ps3? If so what what will they bring and where will they connect it to? thanks

If You are getting a Cable Connection, yes, they will be able to, and as far as DSL is concerned, It shall work fine, As the PS3 is going to have a network card like any other machine and have a MAC address that an IP address will be assigned to. Now if you are getting:

A) Cable: they will need to install a Cable Modem and will need to get Co-ax wire close to your PS3

B) DSL: they will need to install a DSL modem on the closest phone jack.

Personally, I'd recommend the Cable, as Cable beats DSL in almost every category, depending on your ISP.
