Two tiered.. THE three applicationslayers are mapped ontoTwo computer system -the client &the server. client can be-thin client orfat client.Three tier– The three applicationslayers are mapped onto three logicallyseprate processors that executes ondifferent processors.
Another type of network architecture peer to peer ,because each node or instance ofprogram can simultaneous act as both client& a server.
The client queue client allows end points to be simple clients, while the server consists ofsome external s/w, which also acts as a passive queue database. This allows greatlysimplified s/w implementation.
