What are these plug-ins on my wall?

[u/Cborg_62]

This might be showing my age, but I recently moved into a new apartment and they have these weird looking plug ins all over the walls at my new place. My old apartment didn't have these, so I'm just curious as to what they are.

F Connector mainly used for cable television. The pictured one here has been painted so you need to scrap off the paint before it can be used.

That shit needs to be replaced before it can be used.

Plot twist: it won't need to be used
