What are the differences between system fresh and client fresh?

Answer

Client Refresh is a process / mechanisum, in which data in
a target client(development, quality) is usually
overwritten by upated data from a production client. There
are two ways by which it can be achived (1) Client Copy &
(2) Client Export

I guess System Refresh is usually carried out to check the
backup & restore mechanisum in a test enviornment.

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
