Socket.io connection resources question

This might be a stupid question, but I am new to WebSockets and still learning about them.

If I have 3 different server connect actions on a page and each of them has the socket connection turned on is this opening 3 different socket connections? Or are they all inside of one connection?

I might be using the wrong terminology, but basically I’m wondering what the best way to setup these server connect actions with sockets to take up the least amount of server resources.

Is it better to have all of the sever actions combined into one with sockets? Does it matter if there are multiple running on the same page?
