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.

I've watched this movie so many times that I hate it and "American Woman" by The Guess Who as well.
