但是,比如一个打印机驱动程序突然把接磁盘驱动所需的核心代码删除掉,操作系统就会出现部分停顿。
But if, say, a printer driver suddenly erases the kernel code needed to access the disk drive, the operating system will have part of its brain cut out.
在后台,代码为磁盘(在这里加载 LISP 翻译器)、读卡器(在这里读取作业)以及打印机(在这里产生输出)配置仿真器。
Under the covers, the code configures the simulator for the disk (where it loads the LISP interpreter), the card reader (where it reads the job), and the printer (where it emits the output).
例如,打印机可以定位代理主机并传递代码以便为该打印机注册打印服务。
A printer, for instance, could locate a surrogate host and deliver code in order to register a printing service on behalf of the printer.
