The commit charge for each process does not include other major contributions to the process's virtual address space, such as mapped files.
22.
The R4000 has an advanced translation lookaside buffer ( TLB ) where the entry contains not just virtual address but also the virtual address space id.
23.
The "'Kernel Virtual Address Space "'( KVA ) is the virtual memory area in which all Linux kernel threads reside.
24.
TKB also supported overlays; this allowed individual routines to be swapped into the virtual address space as needed, overlaying routines not currently being used.
25.
The additional capability of providing virtual address spaces added another level of security and reliability, thus making virtual memory even more attractive to the market place.
26.
If there are multiple page or segment tables, there are multiple virtual address spaces and concurrent applications with separate page tables redirect to different real addresses.
27.
In many operating systems, paging is used to create an independent virtual address space for each task, preventing one task from manipulating the memory of another.
28.
Sharing of virtual address space and inter-context communications could be provided by writing the same values in to the segment or page maps of different contexts.
29.
IA-32 segments are subdivisions of the computer's " linear address space ", the virtual address space provided by the paging hardware.
30.
The effect of the randomization depends on the CPU . 32-bit CPUs will have 32 bits of virtual address space, allowing access to 4GiB of memory.
