What's the difference bw analog and digital?

I saw this topic https://bbs.archlinux.org/viewtopic.php?id=285244 and decided to try the command in it to see what it will show. Aside from the other devices, it showed this:

card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 1: ALC892 Digital [ALC892 Digital]
  Subdevices: 1/1

I know for sure the card is Realtek ALC892 bc when I bought the motherboard I was still using Windows and I needed to know what driver to use. But I wonder - what's the difference between analog and digital in this case and does it mean anything regarding performance/quality of sound?

most likely your motherboard has a digital/optical output as well as analog 3.5mm jacks

Re: What's the difference bw analog and digital?

Digital and analog are about how information is transferred. Digital does this using the numbers 0 & 1 , while analog uses fluctuating signals instead of numbers.
Analog is much older then digital .

CDs, DVDs and BluRays are digital audio/video media while audiocassette tapes, VHS tapes and LPs are analog audio/video media .
