802.11n
A LAN network design term that refers to a switch interface connected to end-user devices, configured so that it does not use VLAN trunking.
access link
A wireless LAN device that provides a means for wireless clients to send data to each other and to the rest of a wired network, with the AP connecting to both the wireless LAN and the wired Ethernet LAN.
access point
In security, the recording of access attempts.
accounting
In both IPv4 and IPv6, a set of consecutive addresses. This term is typically used for public addresses, assigned by some numbering authority (IANA/ ICANN, an RIR, or an ISP).
address block
The general topic of how on one computer, two adjacent layers in a networking architectural model work together, with the lower layer providing services to the higher layer.
adjacent-layer interaction
In Cisco routers, a means for one router to choose between multiple routes to reach the same subnet when those routes were learned by different routing protocols. The lower the _____, the better the source of the routing information.
administrative distance
One of many DSL technologies, ______ is designed to deliver more bandwidth downstream (from the central office to the customer site) than upstream.
ADSL
