大多数边界是很明显的：网络连接、进程与进程的通信、文件系统、操作系统接口等等，但是有些边界就不好辨别。

Most boundaries are obvious: network connections, process-to-process communication, file systems, operating system interfaces, and so on, but some boundaries are more subtle.

这样就能够避免网络延迟、进程间通信的开销以及操作系统中的上下文切换，从而进一步提高速度。

This avoids network latency and the overhead of inter-process communication, as well as context switching in the operating system, further contributing to extreme speed.

就时间和空间而言，共享内存可能是所有现代操作系统都具备的最高效的进程间通信通道。

In terms of time and space, Shared memory is probably the most efficient inter-process communication channel provided by all modern operating systems.

And if you've ever heard the word driver software that you install in your computer so that your computer, your operating system, Windows or Mac OS, knows how to talk to that piece of hardware, it's that driver software that then empowers the operating systems to send those commands as well, up, the data is laid out on the disk.

并且如果你听说过安装到,电脑中的驱动软件这个词的话，你的操作系统，比如Windows或者是苹果操作系统，通过这个驱动软件我们的电脑，才能知道如何与这个硬件进行通信,正是因为这个驱动软件，操作系统才能根据数据，左右移动的指令来读取磁盘里的数据。
