Explain the Request or Response interface
The Request/Response interface is ideal for a message based client-server interaction. By modeling components to interact via a request and response interface, it is very easy to implement messaging as the vehicle for communication. In order for the Request/Response interface to be a truly acceptable model for procedural interaction, asynchronous callbacks have to be introduced. This was due to the synchronous nature of the interface. Messages are asynchronous and inherently Request/Response in nature. As such, they operate very well in this model.
