Hi Paul; But as the Original Poster, of this simple question, I think you deserve a simple answer. You can learn all about cables, switches and routers later.

One end is connected to a fork or splitter on the incoming cable. Next I have a cheap AOpen router ($20 - $25 US or CAD$) which can take four computer installations connected by a RJ45 line. By luck this house was purchased with lines from every room. That means the router can handle anything up to 100 feet away. Buy as long a RJ45 line as you think you will need. At the risk of sounding like an old song. The incoming TV cable is connected to the splitter and the splitter is connected to the cable modem. The cable modem is connected to the cheap router; and, the cheap router is connected to the first or permanent computer: and the cheap router is then connected to the guest computer; and all works fine. -- Regards Bill
