Fast Ethernet
100Mbps technology based on the Ethernet/CD network access method.
Flow Control – (IEEE 802.3x)
A means of holding packets back at the transmit port of the connected end station. Prevents packet loss at a congested switch port.
Forwarding
The process of sending a packet toward its destination by an internetworking device.
Full Duplex
A system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential throughput of a link.
Half Duplex
A system that allows packets to be transmitted and received, but not at the same time. Contrast with full duplex.
IP Address

IPX
Internetwork Packet Exchange. A protocol allowing communication in a NetWare network.
LAN
Local Area Network. A network of connected computing resources (such as PCs, printers, servers) covering a relatively small geographic area (usually
not larger than a floor or building). Characterized by high data rates and low error rates.
Latency
The delay between the time a device receives a packet and the time the packet is forwarded out of the destination port.
Line Speed
See baud rate.
Main Port
The port in a resilient link that carries data traffic in normal operating conditions.
MDI
Medium Dependent Interface. An Ethernet port connection where the transmitter of one device is connected to the receiver of another device.
