:-)
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.
