Easy simple way to create a networking between 2 computers using bluetooth

I am a beginner programmer for my school and have been given the task of networking a game. I have been searching the internet for the past couple of weeks and have found nothing that actually tells me how to use a network using the internet. it doesn’t necessarily have to be bluetooth but just something that allows me to run a game on 2 computers with one being the server and one being the client. if you could be as detailed as possible and please no links unless they sound like exactly what im looking for

Here’s a couple links that sound like exactly what you’re looking for:

Additionally, this guide is one I followed myself and talks all about setting up a client/server game:

The original guide link is broken, but a number of people have reposted it various places - just read through the thread.
