Single and multiple application server instances

Question:

What is the difference between single and multiple instance
application servers in a multi-tier application?

Answer:

This can best be thought of from the point of view of the 

application server and how many clients can it support.  

One multi-instance server can support multiple clients.

A single instance server can only support one client.

Multi-instance servers create multiple data modules in one

instance of the server. Single instance servers are launched

for each client.
