Difference - router vs access point

[MrGumby]

My ignorance is going to be showing but....can anyone explain what makes an access point different from a router?

More specifically, I have two wireless routers, USR and BT. The USR is in one corner of my house and connected to a broadband modem, the BT unused. Can I use the BT wireless router as an access point, to extend the wireless range of the USR?

Most routers do not support bridging (roaming) functions.

Thanks for that.

"Bridging" - that's the term I was looking for!
