10BASE-T
IEEE 802.3 specification 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.
Auto-Negotiation
Signalling method allowing each node to select its optimum operational mode (e.g., 10
Mbps or 100 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.
Collision
A condition in which packets transmitted over the cable interfere with each other. Their
interference makes both signals unintelligible.
Collision Domain
Single CSMA/CD LAN segment.
CSMA/CD
CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the communication method
employed by Ethernet, Fast Ethernet, or Gigabit Ethernet.
End Station
A workstation, server, or other device that does not forward traffic.
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 operate on
fiber, thin coax and twisted-pair cable.
