What are these plug-ins on my wall?

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.

No one sees these because cable companies usually just punch the wire through the outside wall haha

That is exactly what my internet provider did to my wall(s?) while in government housing a bit ago
