10Base2 - Ethernet specification for thin coaxial cable, transmits signals at 10 Mbps (megabits per second)
with a distance limit of 185 meters per segment.
10Base5 - Ethernet specification for thick coaxial cable, transmits signals at 10 Mbps (megabits per second)
with a distance limit of 500 meters per segment.
10BaseF - Ethernet specification for fiber optic cable, transmits signals at 10 Mbps (megabits per second) with
a distance limit of 2000 meters per segment.
10BaseT - Ethernet specification for unshielded twisted pair cable (category 3, 4, or 5), transmits signals at 10
Mbps (megabits per second) with a distance limit of 100 meters per segment.
100BaseT - Ethernet specification for unshielded twisted pair cabling that is used to transmit data at 100 Mbps
(megabits per second) with a distance limit of 100 meters per segment.
1000BaseTX -Ethernet specification for unshielded twisted pair cabling that is used to trasmit data at 1 Gbps
(gigabits per second) with a distance limitation of 220 meters per segment.
A
Asynchronous Transfer Mode (ATM) - A network protocol that transmits data at a speed of 155 Mbps and
higher. It is most often used to interconnect two or more local area networks.
AppleTalk - Apple Computer's network protocol originally designed to run over LocalTalk networks, but can
also run on Ethernet and Token Ring.
B
Backbone - A cable to which multiple nodes or workstations are attached.
Bit - Binary digit in the binary numbering system. Its value can be 0 or 1. In an 8-bit character scheme, it takes
8 bits to make a byte (character) of data.
BNC Connector (Bayone-Neill-ConcELSan) - Standard connector used to connect 10Base2 coaxial cable.
Bridge - Devices that connect and pass packets between two network segments that use the same
communications protocol.
C
Cable - Transmission medium of copper wire or optical fiber wrapped in a protective cover.
Client/Server - A networking system in which one or more file servers (Server) provide services; such as
network management, application and centralized data storage for workstations (Clients).
CSMA/CD - Carrier Sense Multiple Access Collision Detection is a network access method in which devices
that are ready to transmit data first check the channel for a carrier. If no carrier is sensed, a device can
transmit. If two devices transmit at once, a collision occurs and each computer backs off and waits a random
amount of time before attempting to retransmit. This is the access method used by Ethernet.
Coaxial Cable - Cable consisting of a single copper conductor in the center surrounded by a plastic layer for
insulation and a braided metal outer shield.
Concentrator - A device that provides a central connection point for cables from workstations, servers, and
peripherals. Most concentrators contain the ability to amplify the electrical signal they receive.
E
E-mail - An electronic mail message sent from a host computer to a remote computer.
End User - Refers to the human executing applications on the workstation.
Ethernet - A network protocol invented by Xerox Corporation and developed jointly by Xerox, Intel and Digital
Equipment Corporation. Ethernet networks use CSMA/CD and run over a variety of cable types at 10 Mbps
(megabits per second).
Expansion Slot - Area in a computer that accepts additional input/output boards to increase the capability of
the computer.
