Where is virtual address stored? The virtual address space is kept in secondary storage (disk). The virtual part of virtual memory means that the operating system maintains an image of the address space in secondary storage. Because an image of the address space is kept in secondary storage, it can be larger than the physical memory.
Where is the kernel address space? The operating system supports a flat 32-bit virtual address space. The bottom 2 GB of the address space is for user processes, while the top 2 GB is for the kernel. The kernel address space is statically mapped into the address space.
