The "Host Bridge" is what connects the tree of PCI busses (which are
internally connected with PCI-to-PCI Bridges) to the rest of the
system. Usually the processor(s) and memory are on the "other" side
of the Host Bridge.

On typical PC implementations, this function is embedded in the North
Bridge.
