Abbreviations, Acronyms, and Terms to Know

This glossary defines some of the abbreviations, acronyms, and key terms used in this document.

10Base-5	An Ethernet implementation in which the physical medium is a
	doubly shielded, 50-ohm coaxial cable capable of carrying data at 10
	Mbps for a length of 500 meters (also referred to as thicknet). Also
	known as thick Ethernet.
10Base-2	An Ethernet implementation in which the physical medium is a
	single-shielded, 50-ohm RG58A/U coaxial cable capable of
	carrying data at 10 Mbps for a length of 185 meters (also referred to
	as AUI or thinnet). Also known as thin Ethernet.
10Base-T	An Ethernet implementation in which the physical medium is an
	unshielded twisted pair (UTP) of wires capable of carrying data at
	10 Mbps for a maximum distance of 185 meters. Also known as
	twisted-pair Ethernet.
100Base-TX	An Ethernet implementation in which the physical medium is an
	unshielded twisted pair (UTP) of wires capable of carrying data at
	100 Mbps for a maximum distance of 100 meters. Also known as
	fast Ethernet.
ACIA	Asynchronous Communications Interface Adapter
AIX	Advanced Interactive eXecutive (IBM version of UNIX)
architecture	The main overall design in which each individual hardware
	component of the computer system is interrelated. The most
	common uses of this term are 8-bit, 16-bit, or 32-bit architectural
	design systems.
ASCII	American Standard Code for Information Interchange. This is a 7-
	bit code used to encode alphanumeric information. In the IBM-
	compatible world, this is expanded to 8-bits to encode a total of 256
	alphanumeric and control characters.
ASIC	Application-Specific Integrated Circuit
