Windows内存管理

哎, Windows核心编程被翻译的太烂了。
我需要在这里将内存管理这一章的一些内容给解释清楚：

Partition：Each process's virtual address space is split into partitions.
Region（区域）：是通过VirtualAllocEx函数进行保留的一段虚拟地址空间（The act of allocating a region is called reserving.）
Virtual Memory==Physical Storage==Physical Memory(That is RAM)+ Page File(Or a Memory Mapping file on disk)
Reserve（保留）：The act of allocating a region（in Vritual Address space） is called reserving.
Commit（提交）：allocate physical storage(not RAM) and then map this storage to the reserved region.
Block（块）： A block is a set of contiguous pages that all have the same protection attributes and that are all backed by the same type of physical storage
Process Address Space：A 4G virtual address space

Reserve：开始地址向小的方向调整为分配粒度64K的倍数         保留大小为Page Size的倍数
Commit：开始地址向小的方向调整为Page Size的倍数               保留大小为Page Size的倍数

Memory-mapped file：When a program's file image (that is, an .exe or a DLL file) on the hard disk is used as the physical storage for a region of address space, it is called a memory-mapped file。
