An network access point is where you can wirelessly or wired (depending on the router) gain access to network capabilities it is connected to (eg. internet, domains, remote desktop). The access point when wireless has a WEP/WPA authentication key to prevent unwanted connectors from gain access to those privileges mentioned. The connection goes from the internet modem, then to router (the access point), then to the device you wish to gain network for (whether wireless or wired)
