Network Cable Wall Sockets

Greetings,

Now, we all take them for granted – we just plug our network cable (Cat 5) into the wall socket and we’re on the network. Basically I was wondering if anyone knew any online resources that can explain how to install those Wall Sockets.I have chosen a central point for my hub / switch so all I need to know is the guidelines for installing the network points – I already know how to make the network cables.
Any help would be greatly appreciated.
