内存破坏发生在，当向有效数据段内的一个内存位置写数据却写到了你意图使用的内存块的边界之外。

Memory corruption happens when writing to a location lying inside the legal data segment but outside the boundaries of the memory block you intended to use.

最初可以使用内存块的一个空链表来创建一个抽象缓冲区。

You can initially create an abstract buffer with an empty linked list of memory block.

在POWER 6中，引入了可变页面大小支持(VPSS)，这意味着当应用程序需要更大的内存块时，系统将使用更大的页面。

For POWER6, variable page size support (VPSS) was introduced, which means that the system will use larger pages as the application requests larger chunks of memory.

Well, again, just as I said verbally a moment ago, if you're going here, you're literally touching, trying to read or change memory that's beyond the boundaries of a chunk of memory that you're supposed to be touching based on its length.

嗯，再次强调，就像我刚才说的，如果你从这里出发，你将依次接触到，试着读取或者改变内存,如果超出了你可以使用的,内存块长度的界限。

I have no idea what's here at the moment so I'm just going to draw a question mark because that memory might have been used previously for some other purpose, but we know it's currently available to us so we have four bytes of memory.

我不知道在此刻这里是什么,所以我画一个问号，因为那块内存可能在之前,为其它的目的而使用过，但是我们知道它可以为我们所使用,这样我们就有4个字节的内存。

It's just some random chunk of four bytes that happens to be available at this point in time, but I can put something there.

只是一些随机的四字节的内存块,在这里是可以使用的，但是我可以在那里放置东西。
