Those were seen in a lot of late-90/early 2000s computers and were meant to hold modems and sound cards and such. However, there were very few cards made for those slots as everybody just used PCI slots.

I believe it stand for Communication and Network Riser. I've only seen modem/NICs in them, never a sound card. Dell used them, not sure about anyone else. I might have one in my junk bin, not sure. Not much good for anything.

If your using a PC that has one, you need an upgrade.
