Cable
Thin filaments of glass or other transparent material sheathed in an insulator
through which a light beam may be transmitted for long distances by means of
multiple internal reflections. A waveguide used to transmit digital information.
Flow Control
A method for a receiver to control the information flow from a transmitter. It
eliminates data overflow at the receiver.
FPGA
Acronym for Field Programmable Gate Array.
Full Duplex
A communication method where both ends can transmit and receive
simultaneously.
H
Half Duplex
A communication method where one end transmits while the other end receives,
then reverses the process.
Hub
A device for local area networks (LANs) that is used to interconnect multiple

I
IGMP Snooping
IGMP snooping is the process of listening to IGMP network traffic. IGMP
snooping, as implied by the name, is a feature that allows a layer 2 switch to
“listen in” on the IGMP conversation between hosts and routers by processing the
layer 3 IGMP packets sent in a multicast network.
IP Address
An Internet Protocol (IP) address is a numerical identification (logical address)
that is assigned to network devices, in this case the TC3848-1. Each TC3848-1 in
the network will have its own unique IP address.
