段寄存器

一个逻辑地址包含了段寄存器的说明符及偏移量

A logical address consists of a segment register specifier and offset .

更新段寄存器时，与其相应的段描述符必须在核心内存中修改，然后重新载入段寄存器。

In order to update a segment register , the corresponding segment descriptor must be modified in kernel memory and then reloaded into the segment register .

实际上，检查ds和es段寄存器的内容很重要，因为它们可能被恶意的用户修改。

In particular , it is possible to check the values of the ds and es segmentation registers , which might have been forged by a malicious user .

现行参数栈段寄存器

Current parameter stack segment register

所有进程都使用相同的段寄存器，即它们共享相同的线性地址空间集合的情况下，内存管理相对更简单些。

Memory management is simpler when all processes use the same segment register values that is , when they share the same set of linear addresses .

这一描述与照片相符。指令段描述符寄存器

The description checks with the photograph instruction segment descriptor register

指令段描述符寄存器外部设备命令指示符

指令段描述符寄存器

Instruction segment descriptor register

要使用给定的段描述符，它的值需载入段寄存器中。

To use a given segment descriptor , its value is loaded into one of the segment registers .
