Paging: Difference between revisions

In a paged system, each process may execute in its own 4 GiB area of memory, without any chance of effectingaffecting any other process's memory, or the kernel's. Two or more processes may opt to share memory by mapping the same physical page(s) to addresses in their own address spaces. The virtual address of each mapping do not need to be the same. Consequently, a virtual address in one address space won't point to the same data in other address spaces, in general.
