10BASE-T
IEEE 802.3 specificatiion for 10 Mbps
Ethernet over two pairs of Category 3, 4, or 5
UTP cable.
100BASE-TX
IEEE 802.3u specification for 100 Mbps Fast
Ethernet over two pairs of Category 5 UTP
cable.
1000BASE-LH
Gigabit Ethernet over two strands of 9/125
micron core fiber cable.
1000BASE-LX
IEEE 802.3z specification for Gigabit Ethernet
over two strands of 9/125 micron core fiber
cable.
1000BASE-SX
IEEE 802.3z specification for Gigabit Ethernet
over two strands of 50/125 or 62.5/125
micron core fiber cable.
1000BASE-T
IEEE 802.3ab specification for Gigabit
Ethernet over two pairs of Category 5, 5e, or
6 100-ohm UTP cable.
1000BASE-X
IEEE 802.3 shorthand term for any 1000
Mbps Gigabit Ethernet based on 8B/10B
signalling.
Auto-negotiation
Signalling method allowing each node to
select its optimum operational mode (for
example 10, 100, or 1000 Mbps and half or
full duplex) based on the capabilities of the
node to which it is connected.
Bandwidth
The difference between the highest and
lowest frequencies available for network
signals. Also synonymous with wire speed,
the actual speed of the data transmission
along the cable.
BOOTP
Bootstrap Protocol used to load the operating
system for devices connected to the network.
Collision
A condition in which packets transmitted over
the cable interfere with each other. Their
interference makes both signals unintelligible.
Collison Domain
Single CSMA/CD LAN segment.
CSMA/CD
Carrier Sense Multiple Access/Collision
Detect is the communication method
employed by Ethernet and Fast Ethernet.
Dynamic Host Control Protocol (DHCP)
Provides a framework for passing
configuration information to hosts on a
TCP/IP network. DHCP is based on the
Bootstrap Protocol (BOOTP), adding the
capability of automatic allocation of reusable
network addresses and additional
configuration options.
End Station
A workstation,server, or other device that
does not act as network interconnection.
Ethernet
A network communication system developed
and standardized by DEC, Intel, and Xerox,
using baseband transmission, CSMA/CD
access, logical bus topology, and coaxial
cable. The successor IEEE 802.3 standard
provides for integration into the OSI model
and extends the physical layer and media
with repeaters and implementations that
