10Base2 An IEEE standard for using IEEE 802.3
protocol at 10 Mbps over thin Ethernet cable.
10Base5 An IEEE standard for using IEEE 802.3
protocol at 10 Mbps over thick Ethernet cable.
10BaseT An IEEE standard for using IEEE 802.3
protocol at 10 Mbps over unshielded twisted-pair
cable (the T stands for twisted pair).
100BaseVG An IEEE standard for using the new IEEE
802.12 protocol at 100 Mbps over unshielded
twisted-pair cable of type 5 or type 3.
100BaseT A proprietary standard for using IEEE 802.3
protocol at 100 Mbps over unshielded twisted-pair
cable. IEEE standards approval pending.
802.3 An IEEE standard for the physical layer that
specifies a CSMA/CD protocol. This is the standard
protocol used for Ethernet. Refer to CSMA/CD .
Address The unique code assigned to each device or
workstation connected to the LAN.
Age The process of removing an address from the
unit’s filtering database after the device has not
transmitted for a given period of time.
ANSI American National Standards Institute.
Application layer Layer seven, the uppermost part
of the OSI network layer model. This layer contains
the user and application programs.
ASCII American Standard Code for Information
Interchange, a standard that defines the values that
are used for letters, numbers, and symbols.
