Learning materials for multiplayer??

I want to understand and learn more about networking and multiplayer stuff in unity. Is there any books, YouTube, and etc. that can help me.

Here’s a (paid) course that covers multiplayer using a popular networking library called Mirror: Unity Multiplayer: Intermediate C# Coding & Networking. Worth a look if you enjoy project-based learning.

thank you ill give it a try
