Hello everyone, I’d like to understand how do VLAN tags work. I am a kid starting my IT journey in my first job and I found out about VLAN tags but I have no idea what they do. What is the difference between tagged and untagged? Looking forward to your replies 😊
EDIT: Thank you guys so much for all your replies. I’ve read all of them and now I get it ❤️

So in a nutshell, VLAN tagging is a way to tell traffic apart based on where it should go. Think of your network like a street and a specific VLAN is a club on that street. (Like your management network) You don’t want just any data on the street to get into your club so you give it a wristband with your clubs name on it. That data is now tagged and can access the club. Data without a wristband is untagged and can’t get in.
