Two Nics one workstation

my MB has an integrated Nic.
if I want to add a Nic can I just add one, or must I disable the ON BOARD  and install two PCI Express cards.... or do they make one card two interfaces?

Yes, you can just add one without disabling the onboard NIC and both can function.

Yes, there are cards with multiple  interfaces.  For example:

I see only 2 reasons to add additional card:

1) The motherboard NIC has failed... No need to disable it! It isn't working!  Just add the oter as a replacement.

2) You want connectivity to 2 networks... Possibly a WAN and a LAN... Just add the 2nd card and go... You might then use the workstation as a router as well, between the 2 networks it connects.

It is not necessary to disable the onboard NIC... Just don't plug a cable into it!

A couple more potential reasons to add another card are additional bandwidth and better reliability through reduncancy.

Of course, one has to be careful about proper configuration in any case.

What is the motivation in this case to add another NIC?
