Protection must provide a means for specifying the controls to be imposed
together with a means of enforcement.
When a single sender sending a message to a single receiver is called
multicasting addressing.
In non-blocking primitives, the process remains suspended in receive until a
message arrives, even if it takes hours.
A Multi thread model to construct server can be characterized with
parallelism and having blocking system calls.
