推荐答案

您询问一般的指针？

在大多数操作系统中，他们的逻辑地址。

On most operating systems, they are logical addresses.

操作系统负责将它们转换成物理地址通过虚拟内存和分页机制。这是透明的程序。这就是为什么一个被误导的节目打边界和GPFS。

The operating system is responsible for translating them into physical addresses through the virtual memory and paging mechanism. This is transparent to the program. That's why a misguided program "hits the boundaries" and GPFs.

在一些老的系统（如DOS），他们将身体，让您在内存的其他部分覆盖的东西。

On some old systems (e.g., DOS), they would be physical, allowing you to overwrite stuff in other parts of memory.
