system can look in

exist elsewhere in the filesystem, but relevant applications
aren’t likely to find them unless

/Network. Each of these
Fonts folders exists inside a separate
domain, Mac OS X’s term for

The system defines four domains.
The term “domain” is a contender for the most overloaded word used to describe Mac OS X. While reading this section, try not to confuse the concept of filesystem domains with that of Internet domain names (such as “oreilly.com”) or NetInfo domains (as covered in Chapter 12).
