Thin versus Fat Clients
Thin and Fat (or thick) clients describe how much of the application logic resides on the client.
Little or no application logic resides on a thin client.
All or most of the application logic resides on a fat client.
Thin clients are becoming popular because they are easier to manage, since only the server application logic generally needs to be updated.
The best example of a thin client is World Wide Web architecture which uses a two-tier, thin client architecture (Figure 2-6).
