Rather than storing every pixel of every frame of video separately, video algorithms store information that can be used to predict the color values of pixels.
该版本不是对视频的每一帧的每个像素进行分别的存储，而是通过存储的信息来预测像素点的颜色值。
To reveal the difference in the application code, each panel is further split into two horizontal frames, with the upper frame showing the online store and the lower part showing snippets of the code.
为显示应用程序代码的差异，每个面板进一步分为两个水平框架，上面的框架显示在线商店，下面部分显示代码段。

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。
