ANSI/EIA Standard - 440A: Fiber Optic Terminology
, copyright 1989 by the
Electronics Industries Association (EIA). Copies can be purchased from the
Electronic Industries Association, 2001 Pennsylvania Avenue N.W., Washington,
D.C. 20006. Definitions are identified by the symbol (E) after the definition.
v
The
Information Technology Vocabulary
, developed by Subcommittee 1, Joint
Technical Committee 1, of the International Organization for Standardization and
the International Electrotechnical Commission (ISO/IEC JTC1/SC1). Definitions of
published parts of this vocabulary are identified by the symbol (I) after the
definition; definitions taken from draft international standards, committee drafts,
and working papers being developed by ISO/IEC JTC1/SC1 are identified by the
symbol (T) after the definition, indicating that final agreement has not yet been
reached among the participating National Bodies of SC1.
Numerics
10BASE2.
The IEEE 802.3 Ethernet standard that supports a transmission rate of 10 Mbps using RG 58 A/U and RG
58 C/U coaxial cable and BNC connectors. 10BASE2 is sometimes called thin Ethernet or thinnet.
10BASE5.
The IEEE 802.3 Ethernet standard that supports a transmission rate of 10 Mbps using a 50-ohm coaxial
cable with Type N connectors over a distance of up to 500 m (1640 ft) without using repeaters. 10BASE5 is
sometimes called thick Ethernet or thicknet.
10BASE-FL.
The IEEE 802.3 Ethernet standard that supports a transmission rate of 10 Mbps using optical fiber.
10BASE-T.
The IEEE 802.3 Ethernet standard that supports a transmission rate of 10 Mbps using two twisted-pair
wires (Category 3 telephone wiring). 10BASE-T is the most widely deployed 10-Mbps Ethernet transmission protocol in
use today.
100BASE-T.
The IEEE 802.3 Ethernet standard that supports a transmission rate of 100 Mbps using 2 twisted-pair
wires (Category 5 telephone wiring).
A
access control.
In computer security, the process of ensuring that the resources of a computer system can be
accessed only by authorized users in authorized ways.
access control list (ACL).
(1) In computer security, a collection of all access rights for one object. (2) In computer
security, a list associated with an object that identifies all the subjects that can access the object and their access
rights; for example, a list associated with a file that identifies users who can access the file and identifies their access
rights to that file.
accessory.
An IBM designation for a separately orderable part that (a) has no type number, (b) is for purchase only,
and (c) does not receive normal IBM maintenance.
active-backup.
A type of bond group that provides high availability. Two or more ports are combined under a logical
bond group with one link active and the other link or links left idle. The idle links are ready to take over in the event
that the currently active link fails. See bond group.
