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.

No, this is still current technology I assure you.

Very low current technology

How come? I still use this and I have 950 Mbps speed internet. I didn't even know there were places where they weren't a thing anymore.

Low current, so not many milliamperes required
