不过，共享内存段依然不能跨越象限边界。

However, Shared memory segments still can not cross quadrant boundaries.

All right so it has to live in RAM as opposed to the hard drive because otherwise things would be terribly slow as you know so it's much better if your programs live while they're running in RAM and they end up in what's called the tech segment.

好的，它存在内存中，而不是硬盘中,因为，否则程序会非常的缓慢,程序在内存中运行会好得多,它们在技术段,的地方结束。

你可能不会倒胃口地调用,但是段错误是涉及内存段冲突。
