假如，现在你要写一个计算加法的小程序，这个程序需要的输入来自于一个文件，计算完成后的结果则输出到另一个文件中。由于计算机只认识 0 和 1，所以无论用哪种语言编写这段代码，最后都需要通过某种方式翻译成二进制文件，才能在计算机操作系统中运行起来。而为了能够让这些代码正常运行，我们往往还要给它提供数据，比如我们这个加法程序所需要的输入文件。这些数据加上代码本身的二进制文件，放在磁盘上，就是我们平常所说的一个“程序”，也叫代码的可执行镜像（executable image）。
首先，操作系统从“程序”中发现输入数据保存在一个文件中，所以这些数据就被会加载到内存中待命。同时，操作系统又读取到了计算加法的指令，这时，它就需要指示 CPU 完成加法操作。而 CPU 与内存协作进行加法计算，又会使用寄存器存放数值、内存堆栈保存执行的命令和变量。同时，计算机里还有被打开的文件，以及各种各样的 I/O 设备在不断地调用中修改自己的状态。
对于 Docker 等大多数 Linux 容器来说，Cgroups 技术是用来制造约束的主要手段，而 Namespace 技术则是用来修改进程视图的主要方法。
