Cooperative processing is computing which requires two or more distinct 
processors to complete a single transaction.  Cooperative processing is 
related to both distributed and client/server processing. It is a form of 
distributed computing where two or more distinct processes are required to 
complete a single business transaction. Usually, these programs interact 
and execute concurrently on different processors. Cooperative processing 
can also be considered to be a style of client/server processing if 
communication between processors is performed through a message 
passing architecture.
