access interface - ANSWERSA LAN network design term that refers to a switch interface connected to
end-user devices, configured so that it does not use VLAN
, access point - ANSWERSA 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 connectinge to
Both the wireless LAN and the wired Ethernet LAN.
ARP - ANSWERSAddress Resolution Protocol. An Internet protocol used to map an IP address to a MAC
address. Defined in RFC 826.
ARP table - ANSWERSA list of IP addresses of neighbors on the same VLAN, along with their MAC
addresses, as kept in memory by hosts and routers.
Authentication - ANSWERSIn security, the verification of the identity of a person or a process.
autonomous system - ANSWERSAn internetwork in the administrative control of one organization,
company, or governmental agency, inside which that organization typically runs an interior gateway
protocol (IGP).
Bandwith - ANSWERSA reference to the speed of a networking link. Its origins come from earlier
communications technology in which the range, or width, of the frequency band dictated how fast
communications could occur.
Binary mask - ANSWERSAn IPv4 subnet mask written as a 32-bit binary number.
Boolean AND - ANSWERSA math operation performed on a pair of one-digit binary numbers. The result
is another one-digit binary number. 1 and 1 yields 1; all other combinations yield a 0.
Broadcast address - ANSWERSGenerally, any address that represents all devices and can be used to send
one message to all devices. In Ethernet, the MAC address of all binary 1s, or FFFF.FFFF.FFFF in hex. For
IPv4.
Broadcast domain - ANSWERSA set of all devices that receive broadcast frames originating from any
device within the set. Devices in the same VLAN are in the same broadcast domain.
