   10BaseT

      twisted pair cable.  See also: Ethernet, twisted pair.

   802.x

   :-)
      This odd symbol is one of the ways a person can portray "mood" in
      the very flat medium of computers--by using "smiley faces".  This
      is "metacommunication", and there are literally hundreds of such
      symbols, from the obvious to the obscure.  This particular example
      expresses "happiness".  Don't see it?  Tilt your head to the left
      90 degrees.  Smiles are also used to denote sarcasm.

   abstract syntax
      A description of a data structure that is independent of machine-
      oriented structures and encodings.
      [Source: RFC 1208]

   Abstract Syntax Notation One (ASN.1)
      The language used by the OSI protocols for describing abstract
      syntax.  This language is also used to encode SNMP packets.  ASN.1
      is defined in ISO documents 8824.2 and 8825.2.  See also: Basic
      Encoding Rules.

   Acceptable Use Policy (AUP)
      Many transit networks have policies which restrict the use to
      which the network may be put.  A well known example is NSFNET's
      AUP which does not allow commercial use.  Enforcement of AUPs
      varies with the network.  See also: National Science Foundation.

   Access Control List (ACL)
      Most network security systems operate by allowing selective use of
      services.  An Access Control List is the usual means by which
      access to, and denial of, services is controlled.  It is simply a
      list of the services available, each with a list of the hosts
      permitted to use the service.

   ACK
      See: Acknowledgment
