Section 5 -Glossary
console port
The port on the Switch accepting a terminal or modem connector. It changes the parallel arrangement of data
within computers to the serial form used on data transmission links. This port is most often used for dedicated local
management.
CSMA/CD
Channel access method used by Ethernet and IEEE 802.3 standards, in which devices transmit only after finding
the data channel clear for some period of time. When two devices transmit simultaneously, a collision occurs and the
colliding devices delay their retransmissions for a random amount of time.
data center switching
The point of aggregation within a corporate network where a switch provides high performance access to server farms,
a high-speed backbone connection, and a control point for network management and security.
Ethernet
A LAN specification developed jointly by Xerox, Intel, and Digital Equipment Corporation. Ethernet networks operate
at 10Mbps using CSMA/CD to run over cabling.
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.
