虚拟地址

To associate an absolute address, virtual address or device identifier with a symbolic address or label in a computer program.

在计算机程序中，将绝对地址、虚拟地址或设备标识符与符号地址或标号联系起来。

A disk array that is capable of changing its algorithm for virtual data address to physical data location mapping dynamically (i.e., while the array is operating).

一种磁盘阵列，它能够动态地改变将虚拟地址映射为数据的物理地址的算法（在磁盘阵列正在运行的时候）。

Given a 32 bit virtual address from kuseg, we get the physical address as follows

对于kuseg的一个32位虚拟地址，通过如下方法得到物理地址

And you generally _never_ want to use the physical address, because you can't use that from the CPU (the CPU only uses translated virtual addresses), and you can't use it from the bus master.

实际上你从来不需要使用物理地址，因为你不能在CPU上使用这个地址（CPU只使用映射后的虚拟地址）你也不能在外设上面使用这样的地址。

According to virtual router advertise, virtual address of master device is used to upstream access device, which enables downstream traffics to have the same flow direction with that of upstream traffics via routing.

虚拟路由通告的方法则把主设备中的虚拟地址通告给上行接入设备，从而下行流量可以通过上行设备的选路，使上下行数据流向保持了一致。

Systems which use multiple page tables provide multiple virtual address spaces - concurrent applications think they are using the same range of virtual addresses, but their separate page tables redirect to different real addresses.

系统使用多个网页表格提供多个虚拟地址空间-并行应用程序认为他们使用的是相同的虚拟地址范围内，但其独立的页面重定向到不同的表真正地址。

When the hardware is unable to find a physical frame for a virtual page, it will generate a processor interrupt called a page fault .

如果硬件无法找到虚拟地址对应的物理地址，就会产生一个叫做"页错误"的处理器中断。

If there is only one, different applications which are running at the same time share a single virtual address space, ie they use different parts of a single range of virtual addresses.

如果只有一个，不同的应用程序是运行在同一时间共享一个虚拟地址空间，也就是说，它们使用不同地区的一个单一的范围内的虚拟地址。

Because multiple memory locations must be accessed to resolve each virtual memory address, virtual address translation using page tables is a expensive operation.

由于分解每个虚拟内存地址都必须访问多个内存定位，用页表进行虚拟地址的转换是很繁琐的操作。

This operation will then give us a system virtual address which we can then use to read the memory.

这个操作可以给我们一个系统虚拟地址，我们可以使用这个虚拟地址来读内存。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
