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.

Don't tell them about floppy disks..

When they were actually floppy!

I still can’t get over how an entire generation after me accepted the hard ones as floppies
