How VMware sees Physical Adapters

$

Hello,

 

I'm trying to reinforce my understanding of vSS and vDS for VCAP study and I'm after some clarification.

 

When we're talking about Physical Adapters in VMware and when I see them in the GUI, am I right in assuming we're talking about one of these:

That is, a Physical Adapter with one port. And this looks like this in VMware:

If that is the case then I can relate to that quite easily. If a server has 8 NICs (or 6 in the example above) then that is correctly represented above. However, what if we're using one of these:

A four port NIC? How is that represented in VMware? Am I right in assuming like this:

What's confusing me is that when I create a vDS I'm asked how many uplink ports I need and underneath it says 'Maximum number of physical adapters per host'. Are these supposed to be one and the same thing?

Because if we stick to the 8 separate physical NICs all with 1 port each then I can understand that but at work we have two 4 port NICs and that's skewing my perception somewhat.
