And how is the name assigned ?

Yes, and it's also associated with the hardware. On a system with a
add-on PCI ethernet called eth0, if you remplace it by another PCI ethernet
(even if it's the same model, as the name is actually attached to the
ethernet address) it'll be called eth1. You have to edit sysconfig files
to have it named eth0 again.
