Types Of Interprocess Interaction
Technology Expanded Memory (Mapped Memory)

Interprocess
So far, we have considered the interaction of flows of one process. The
main feature of this interaction is the ease of technical implementation of
data exchange between them - one process flow using one address space
and therefore, can freely access the co-usage of variant data as if they were
their own. Since there are no technical difficulties with the implementation
of data exchange, the main problem that needs to be solved in this case is
the synchronization of flows.
On the other hand, each thread is executed within the address space of a
process, so the task of organizing interaction between the flows of different
processes is often a problem. The question itself about interprocess
interaction ( interprocess communication or IPC ) .
For streams of different processes, the issues of synchronization are also
relevant, but in most cases, they are not based on the concept of shared data
(such default data for processes are missing). In addition, the challenge of
securing exchange between protected address spaces is added. Approaches
to its solution define different types of interprocess interaction.

Types Of Interprocess Interaction
Implementation of inter processing is accomplished by three basic
methods: message passing, memory allocation, and displayed memory.
Another method of IPC is to consider the signal technology discussed
earlier.
Technology Expanded Memory (Mapped Memory)
In a number of operating systems, the displayed memory is the basic system
mechanism on which other types of interprocess interaction and system
decisions are based. Of course, the display memory used in conjunction
with the file system interface, in this case, talking about the files displayed
in the memory ( memory-mapped files ).
This technology is to ensure that a special system call (usually mmap ()) a
