Whenever I see a headphone plug, it has lines on it, those being from a number of 1 to 3. Why is this?

I think people have covered it already but basically 1 ring is mono, two is stereo and 3 is stereo + microphone
I actually helped someone out on the techsupport subreddit for this. They had a desktop pc with a separate microphone and headset port, while their headset had a single 3 ring jack
The desktop PC inputs werent capable of using the single cable with 3 rings so you can get a splitter to split it into two jacks if you need
