1. operating system A name, usually short and easy to
remember and type, that is translated into another name or
string, usually long and difficult to remember or type. Most
command interpreters (e.g. Unix's csh) allow the user to
define aliases for commands, e.g. "alias l ls -al". These are
loaded into memory when the interpreter starts and are
expanded without needing to refer to any file.
2. networking One of several alternative hostnames with
the same Internet address. E.g. in the Unix hosts
database (/etc/hosts or NIS map) the first field on a line
is the Internet address, the next is the official hostname
(the "canonical name" or "CNAME"), and any others are
aliases.
Hostname aliases often indicate that the host with that alias
provides a particular network service such as archie,
finger, FTP, or World-Wide Web. The assignment of
services to computers can then be changed simply by moving an
alias (e.g. www.doc.ic.ac.uk) from one Internet address to
another, without the clients needing to be aware of the
change.
3. file system The name used by Apple computer, Inc. for
symbolic links when they added them to the System 7
