Virtual Switch Manager: External, Internal or Private?

Tried of reading far too technical jargon without seeing any simple answers.

I'm attempting to configure the virtual switch for the Hyper V I just activated on my Win8.1 Pro and wish to installed Windows Server 2012 on it.

So, I'm stumped at which to select, External, Internal or Private? We have a network of several computers but once Hyper V is successfully set up, I hope I'll be using my Windows 8 / Server 2012 on the same machine with the server hosting a news website on the net, on all the time. The NIC on this computer, one of two nics, is connected to a Frontier router to the internet, and also to a Cisco router to serve other computers. All control and setting of the Windows server will be only from this one computer. It's a pretty simple set up.

Once selected, is there any way to change the the virtual switch designation once created? Hate the idea of being locked into something, especially something I don't understand. So, that's why I'm here for the experts.

But which should I select, External, Internal or Private for the virtual switch?

There is a great explaination here......

For what you explain you would use "External" this is easily changed after you have configured it so you wont be locked in.
