American Standard Code for Information Interchange

See ASCII.

AppleTalk

An Apple Computer, Inc., trademark for their network protocol suite.

ASCII

American Standard Code for Information Interchange. A set of 8-bit binary numbers representing the alphabet, punctuation, numerals, and other special symbols used in text representation and communications protocols.

asynchronous

Pertaining to a communication method in which each event occurs with no relation to a timing signal.

atomics

Refers to nontabular objects in a group of objects in a MIB.

authentication

Utilizes Kerberos to verify a user’s identity by validating a Kerberos user name and password on a remote Kerberos host (KDC).

authentication trap

An SNMP trap message that is sent to each community with TRAPS enabled whenever an unauthorized Internet host tries to access the access server, or when an Internet host uses an unauthorized SNMP GET or GETNEXT message.

autobaud

The process by which the access server automatically determines the line speed and other characteristics of a terminal attached to one of its ports.

autoconnect

A feature whereby the access server automatically attempts to reconnect a port to a network resource in the following situations: the port becomes disconnected from a resource, the user enters a CONNECT command and the specified resource is unavailable, or the user logs in to a port that has a preferred service defined.

automatic failover

See failover.

bootptab file

This is the file that BOOTP uses to store information necessary to downline load software. The bootptab file is normally shown as /etc/bootptab.
