10BASE-T
10 Mbps Ethernet on twisted-pair (Category 3)
cable.
100BASE-T
The twisted pair version of 100 Mbps Ethernet.
Requires Category 5 cabling.
1000BASE-T
A recent LAN standard for implementing 1000
Mbps Ethernet on Category 5 cable. Also called
Gigabit Ethernet.
Auto-MDIX
A protocol which allows two Ethernet devices to
negotiate their use of the Ethernet Transmit (Tx) and
Receive (Rx) cable pairs. This allows two Ethernet
devices with MDI or MDI-X connectors to connect
without using a cross-over cable.
Baud
A unit of measurement that denotes the number
of bits that can be transmitted per second. For
example, if a modem is rated at 9600 baud it is
capable of transmitting data at a rate of 9600 bits
per second.
Bandwidth
The maximum capacity of a network channel.
Usually expressed in bits per second (bps). Ethernet
channels have bandwidths of 10, 100, and 1000
Mbps (Gigabit).
bps
Bits Per Second is the unit used for measuring line
speed, the number of information units transmitted
per second.
Broadcast
A transmission initiated by one station and sent to
all stations on the network.
Byte
The amount of memory needed to store one
character such as a letter or a number. Equal to 8 bits
of digital information. The standard measurement
unit of a file size.
Category 5
A performance classification for twisted pair cables,
connectors and systems. Specified to 100 MHz.
Suitable for voice and data applications up to 155
Mbps.
RJ FIELD GLOSSARY
56
Category 5 e
Also called Enhanced Category 5. A performance
classification for twisted pair cables, connectors
and systems. Specified to 100 MHz. Suitable for
voice and data applications up to 1000 Mbps.
Category 6
A performance classification for twisted pair cables,
connectors and systems.Specified up to 250 MHz.
CSMA/CD
Carrier Sense Multiple Access/Collision Detect. The
Medium Access Control (MAC) protocol used in
Ethernet.
Data rate
The speed of the data transmission, measured in
bps (bits per second) or Mbps.
Duplex (Full, Half)
Full duplex is a communications method that allows
for the simultaneous transmission and reception of
data. In Half Duplex communication, transmissions
and receptions can occur in either direction but not
at the same time.
Ethernet
The
use. A protocol is a set of rules enabling data
communications. Ethernet can operate over several
different media including fiber optic, coaxial cable
and twisted-pair cable.
IEEE 802.3
IEEE Working Group for CSMA/CD, the protocol
used in Ethernet transmissions.
IGMP snooping
The ability of a switch to observe Internet Group
Multicast Protocol (IGMP) traffic in order to learn
IP Multicast group membership. The purpose is to
restrict multicast transmissions to only those ports
which have requested them.
LAN
Local Area Network. A network of directly-
connected machines (located in close proximity),
providing high speed communication over physical
media such as fiber optics, coaxial cable, or twisted
pair wiring.
