存储转发交换机将帧存储在内部存储器中,检查错误然后将其转发至目的地。 存储转发操作确保了网络流量的高正确率,因为错误的数据帧被丢弃,而不会在网络中转发,如图6-9所示。

如果您想在系统提供的备用存储器之外保存和恢复首选项,您可以在xml格式的文档中执行这些操作。
If you want to save and restore preferences outside of the system-provided backing storage, you can do so in an XML-formatted document.
该系统将包含一个处理器、一个存储器和一个操作界面。

Or take this value out of memory, run it through some other simple operation, stick it back in memory.
或者从记忆存储器中取出一个结果,在类似的操作中运行,再插回到存储器中。
A low-level language, we used to call this assembly programming, you're down at the level of, your primitives are literally moving pieces of data from one location of memory to another, through a very simple operation.
一个低级的语言,我们曾经将其称为假设编程,你们只是处于用基本要素,把一些数据碎片,从记忆存储器的一个地方,通过简单的操作来转到另外一个地方。
