802.11g and 802.11b compatability

Stupid and probably very simple networking question: how compatible are the 802.11g and 802.11b protocols? Can a 802.11b networking card and 802.11g router be used together harmoniously?
An 802.11g router will handle both b and g. The drawback is that if you have a g device it will run at the lower b speed.

Not only that, but most 802.11g routers can run in 802.11b mode.

Yes, mostly. 802.11g routers are backwards-compatible with 802.11b cards, as long as they aren't too old. The 11b standard called for support of 8 different data rates, but 11g supports 12. If the 11b card isn't running recent firmware, it might not be able to join an 11g network.

I thought the spec was that it'll run at G in B/G mode until a B client connects, then everything drops to B.
