In a wireless network, an access point sends and receives signals to any number of other, local wireless devices. These are usually adapters and routers.
An access point is different from a wireless router, in that it does not have a firewall and therefore is not appropriate to protect your local network against threats from the Internet. A basic wireless setup may not have an access point, but just a router (or a modem) and an adapter.
An access point extends the coverage within your network — it's put in a "dead spot", a place that's distant from the router, perhaps in a different room, or on a different floor.
