How do I find my network protocols?

Excuse me, I'm having a bit of trouble finding my network protocols. Could you possibly walk me through the process of how I can locate them? I'm not exactly sure where to start looking and I'd appreciate any guidance you could offer. Is there a specific software or tool that I should be using to find them? Or is there a series of steps I can follow on my computer or device? I'm hoping to resolve this issue as soon as possible, so any help you can provide would be greatly appreciated. Thank you in advance for your time and assistance.
