They implement "Bridge Adapter" (vboxnetflt) and "Host-only Adapter"
(vboxnetadp).

Bridge is what it sounds like, it will bridge the guest interface with a
physical interface. So, if you want your guest to be a part of
your network, select "Bridge Adapter" and the select your physical
ethernet interface in the drop-down list.

Host-only adapter can be used to create a virtual network among guests
and the physical machine. It creates a vboxnetX interface that acts like
it's connected to a separate ethernet segment to which the guests
are connected.

I don't know how the TAP stuff works.
