1 - About
Each process has its own virtual memory, which grows when the process requests more memory from the operating system, and shrinks when the process relinquishes unused memory.

3.1 - Shared
Shared memory is a method to
share data between processes.
Both processes define the same memory area as
shared, and they can then exchange information simply by writing into it.
This (used to be, and still is somewhat) faster than the alternative of sending network or pipe-based messages between processes.
