Answer / sanjay
Instance could be defined as a combination of one or more
process addition with memory allocation. it might be central
instance, dialog instance or database instance. each n every
instance have certain number of work processes with instance
specific memory area.
dispatcher and workprocess could be a part of instance but
not defined as a complete instance without memory.
server comes from the logic of parent and child relationship
in between two applications. one the parent application is
known as domain server, and others child applications are
known as clients, and managed from the server.

In plain terms 'Server' means a object/componenet that
services request.
Instance in SAP
=================
An Instance in SAP is a combination of Application Server &
Database Server i.e.
When you use the SAP GUI to connect to the Application
Server, the application server in turn communicates to the
database server to service your requests.
The entire Instance is divided into subcomponents
(Application server, Database server) so that the
complexity is reduced, maintenance & deployement becomes
easy. The above are some of the advantages, to understand
what it all means hou have to get hold of some material
that dwelves on 'Client-Server' ARchitecture
