2. Virtual memory compression - Wikipedia

   en.wikipedia.org/wiki/Virtual_memory_compression

   By reducing the I/O activity caused by paging requests, virtual memory compression can produce overall performance improvements. The degree of performance improvement depends on a variety of factors, including the availability of any compression co-processors, spare bandwidth on the CPU, speed of the I/O channel, speed of the physical memory, and the compressibility of the physical memory ...

3. Commit charge - Wikipedia

   en.wikipedia.org/wiki/Commit_charge

   This is composed of main memory (RAM) and disk (pagefiles). The corresponding performance counter is called "Committed Bytes". Limit is the maximum possible value for Total ; it is the sum of the current pagefile size plus the physical memory available for pageable contents (this excludes RAM that is assigned to non-pageable areas).

4. Virtual memory - Wikipedia

   en.wikipedia.org/wiki/Virtual_memory

   Virtual memory combines active RAM and inactive memory on DASD [a] to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, [b] is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" [3] which "creates the illusion to users of a very large (main) memory".

5. Memory virtualization - Wikipedia

   en.wikipedia.org/wiki/Memory_virtualization

   Virtual memory systems abstract between physical RAM and virtual addresses, assigning virtual memory addresses both to physical RAM and to disk-based storage, expanding addressable memory, but at the cost of speed. NUMA and SMP architectures optimize memory allocation within multi-processor systems. While these technologies dynamically manage ...

6. RAM limit - Wikipedia

   en.wikipedia.org/wiki/RAM_limit

   Bank switching allows blocks of RAM memory to be switched into the processor's address space when required, under program control. Operating systems routinely manage running programs using virtual memory, where individual program operate as if they have access to a large memory space that is being simulated by swapping memory areas with disk ...

7. Page (computer memory) - Wikipedia

   en.wikipedia.org/wiki/Page_(computer_memory)

   A page, memory page, or virtual page is a fixed-length contiguous block of virtual memory, described by a single entry in a page table.It is the smallest unit of data for memory management in an operating system that uses virtual memory.
