What Exactly Is a Network ID and How Does It Work? or Can Someone Explain the Purpose of a Network ID

"Can someone explain the purpose of a network ID in simple terms?"

Hey guys, I keep hearing about *network id* but tbh, I’m kinda lost. Like, what’s the point of it?

Is it just some fancy label for my wifi or does it actually do something important? And why do devices even need it?

Also, if it’s so crucial, how come I’ve never really noticed it before? 🤔

Would love a dumbed-down explanation—no tech jargon pls!

Thanks in advance!

(Also, bonus q: how do I even *find* my network id? Is it the same as my wifi name?)
