On 32-bit x86 systems, the total virtual address space is of 4GB. By default, Windows allocates half of this address space to processes for their unique private storage and the other half for its own protected system memory utilization. Since 2GB is not enough virtual address space to map very large databases, which Windows mechanism can be used by 32-bit applications to allocate up to 64GB of physical memory and to map views into its 2GB virtual address space?
A. Tracer
B. Driver signing mechanism
