Hope this is the right area for this question.
Basically I've moved into a new flat which has some ports I've never seen before in any previous house I've been in.
Ok, so this first picture I assume is just a standard telephone socket (my router is plugged in here)
The second image is in a box above the phone socket (I've taken the front cover off). I have no idea what this is for.
The third image shows some sockets which are in every room (some rooms have more than one of these). Looks like an Ethernet socket to me.
Right now, as I only have that one phone socket in a cupboard, that is where the router is kept, and I'm accessing the internet over WiFi.
Would it be possible to connect everything up using wires with these sockets, or have I got the wrong idea with what they are for?
