Client server 1 Overview
The application logic is distributed across at least one client and at least one
server.
Each component can be on the same or different computer than others.
Each component runs as a process, therefore communication between them is
at layer 4 (the Transport Layer).
Normally the ‘server’ provides some sort of service to the Clients.
Communication is usually initiated by the Clients.
Clients typically do not interact directly.
