forwarding
The process by which the bridge transfers a packet received from one LAN to the port for
transmission onto the other LAN.
IEEE 802.3 standard
Part of the Institute of Electrical and Electronics Engineers 802 family of LAN standards.
The 802.3 standard defines the physical layer (layer 1) and part of the data link layer
(layer 2) of the ISO OSI reference model for a CSMA/CD LAN. The IEEE 802.3
standard evolved from Ethernet, but the two networks are not fully compatible with each
other.
LAN
local area network
A general-purpose communications network that interconnects a variety of devices within
a limited geographical area. Two common LANs, IEEE 802.3 and Ethernet, have
compatible cabling requirements, and can co-exist on a common installation, but have
different protocols. A LAN might connect computers on adjacent desks, within a
building, or within several buildings of a campus. See also extended LAN.
LAN cable
The medium through which data moves in a LAN. LAN cables come in many types. For
example, thick (10 mm) coaxial cable, thin (5 mm) coaxial cable, fiber-optic cable, and
twisted-pair cable.
LED
light emitting diode
A small light on a device that is often used to provide status information.
loopback connector
A connector that loops transmitted messages back to their origin for comparison with the
original transmission. This allows a test of the bridge's network port I/O circuitry.
