What exactly is an n-tier application?
Does it only apply to distributed computing?
Where is a good source of information that I can read so I could see if it applies to anything that I might be doing?
Am I right in saying that a standard client/server model is two tier?

An n-tier application is an application logically/physically separated into several layers.

Not necessarily. It can be applied to desktop applications.
