Collision Domain
Single CSMA/CD LAN segment.
Customer Premises Equipment (CPE) 
Terminating equipment, such as terminals, phones, routers and routers, supplied by 
the phone company, installed at customer sites, and connected to the phone 
company network.
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.
Fast Ethernet
A 100 Mbps network communication system based on Ethernet and the CSMA/CD 
access method.
Fiber to the Home (FTTH)
A network where an optical fiber runs from the service provider to the subscriber's 
premises or home. 
Gigabit Ethernet
A 1000 Mbps network communication system based on Ethernet and the CSMA/CD 
access method. 
Full Duplex
Transmission method that allows two network devices to transmit and receive 
concurrently, effectively doubling the bandwidth of that link.
IEEE
Institute of Electrical and Electronic Engineers.
IEEE 802.3
Defines carrier sense multiple access with collision detection (CSMA/CD) access 
method and physical layer specifications.
