1. Message passing models (Erlang, for example) do not have any shared state; all synchronization and communication is done by exchanging messages. Shared memory models communicate by reading/writing to shared memory blocks, which are protected by semaphores or similar. Message passing's pro

1.If we delivery less information to computers,we prefer to using message passing than shared-memory model. Message passing: information through the operating system provide links between trips to the Exchange. Pros: message delivery method is useful only in the minority when the information

1. I think the suitable situation to use message passing is when you are going to exchange smaller amounts of data. The benefits of using message passing are it is easier to implement than shared memory for inter-computer communication. Message can be exchange directly or indirectly through mailb
