100BASE-TX
IEEE’s specifications for 100 Mbps Ethernet using twisted-pair cable (100W Cat. 5 STP
or UTP). The maximum length of cable for a point-to-point connection is 100 meters
(328 feet).
100BASE-FX
IEEE’s specifications for 100 Mbps Ethernet using multimode fiber optic cable. The
100BASE-FX Switch Module can be used to support fiber optic cable with SC or
ST-type connectors. The maximum length for a point-to-point connection is 2
kilometers (1.24 miles) at full duplex, or 412 meters (0.25 miles) at half duplex.
Collision
A condition in which two packets transmitted over a medium interfere with each other.
Their interference makes both signals unintelligible. The transmitting devices have to
halt transmission for a random period of time before trying to send data again.
Configuration
The way to set up a computer, server, or local area network.
Connection
A logical binding between two or more users of an interconnection service.
Daisy-Chain Port
An MDI RJ-45 port used to attach compatible devices in a daisy-chain configuration
using straight-through twisted-pair cable. To attach a device, either run a connection
from the daisy-chain port on one device to a station port on the other device, or cascade
the two devices by running crossover cable between MDI-X station ports on both
devices.
