Glossary
Media converter:
for example, Ethernet (100Base-TX) to fiber optic (100Base-FX).
Multicast bundle:
they are transmitted to all devices on the network regardless of whether any devices are con-
figured to receive them. Multicast bundles allow point-to-multipoint connections and can
be used with repeater hubs or switching hubs. Advantages include the ability to distribute
digital audio to any number of devices simply by configuring those devices to receive the
same bundle. Disadvantages are that all available network bandwidth is used, devices
receive all bundles and must decide for themselves whether to receive or ignore the data,
and any 10Base-T data ports (e.g., computers, printers, etc.) will be flooded with data. It can
be stressful for switching hubs, which must work hard to transmit all incoming data to all
output ports. Contrast with Unicast Bundle.
Network topology:
star, ring, tree, and bus. Ethernet networks utilizing hubs are typically wired in a star topol-
ogy, although a network may consist of various topologies.
Performer:
synchronize to the conductor. See also Conductor.
Repeater hub:
ports.
RJ-45 connector:
1000Base-T Ethernet devices.
RS-232C:
tance of approximately 15 meters, typically using 9- or 25-pin D-sub connectors.
RS-422:
sion distance of approximately 1 kilometer and higher data rates and greater immunity
to interference than RS-232C.
RS-485:
with support for multiple receivers and transmitters, offering bidirectional half-duplex
communications over a single twisted pair.
Sampling rate:
Serial Bridge:
transmitted over the network. Due to the process of packetizing and re-serializing serial
data, data sent over the Serial Bridge is delayed approximately 10 milliseconds.
Straight Ethernet cable:
nects to pin 1, pin 2 to pin 2, and so on). Straight cables are used to connect Ethernet devices
to networks. You can easily tell whether an Ethernet cable is crossover or straight by looking
at the wiring of both connectors. If the wiring is identical, it's a straight cable. If it's different,
it's a crossover cable. Contrast with Crossover Ethernet cable.
STP (Shielded Twisted Pair):
twisted together.
Switching hub:
address of each device on the network and automatically route network traffic accordingly,
so each device receives only data addressed to it.
