1. -Message passing model is more suitable to use when you are doing something more simple , and protect data from being edited by other who shouldn’t access the file. -Shared-memory model can simulate the message passing model , but vice versa, it does not work, Shared-memory model has a disa

1.Distributed memory machines use message passing to communicate data between processors at programmer-determined points in the program’s execution. Message passing offers the potential of high performance and allows easy and relatively inexpensive scaling the system by adding more workstations to t

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 mailbox

1.Reason 1: caches are useful when two or more components need toexchange data, and the components perform transfers at different speeds. E.g., the CU registers and the disk are wo such components. Caches solve this problem byproviding a buffer of intermediate speed to store part of the data
