The UNIX operating system is made up of three parts; the kernel, the shell and the programs. The kernel of UNIX is the(71)of the operating system: it allocates time and memory to programs and handles the filestore and communications in response to(72). The shell acts as an(73)between the user and the kernel. When a user logs in, the(74)program checks the username and password, and then starts another program called the shell. The shell is a command line(75)(CLI). It interprets the commands the user types in and arranges for them to be carded out. The commands are themselves programs: when they terminate, the shell gives the user another prompt(% on our systems).

    正确答案：C
    解析：试题(71)分析：该题考查嵌入式操作系统的定义，嵌入式操作系统是在boot loader对嵌入式设备进行初始化引导启动后，管理运行在设备上的所有其他程序的软件。故C选择software符合嵌入式系统的定义，为该题的正确选项。
    嵌入式操作系统是在引导装入程序(boot loader)对嵌入式设备进行初始化引导启动后，管理运行在设备上的所有其他程序的软件。嵌入式系统在实现应用程序的同时，能保证软件的存储空间和操作的时间满足一定的要求。嵌入式操作系统都较小，一般仅包含初始引导装入程序、操作系统内核、设备驱动程序和用于存储用户数据的文件系统。嵌入式系统与常见的操作系统在结构上非常相似，区分它们的主要因素有预安装设备、功能有限和仅执行特别设计的任务等。
      试题(72)分析：该题考查嵌入式系统各个组成部分的功能定义，其中boot loader处于整个软件系统的底层，用于对硬件的初始化引导，相当于PC中的BIOS，故该题选项为D。
      试题(73)分析：嵌入式系统在实现应用程序的同时，对软件的存储体积和操作的时间有一定的要求，故B选项storage符合对存储的定义，为正确答案。
      试题(74)分析：嵌入式操作系统对程序运行的时间根据优先级的高低限定了时间，对其完成操作的时间进行了限制，保证这个系统的正常运行。故选项为A。
    试题(75)分析：嵌入式操作系统中包含设备驱动程序和文件系统，后者用于对用户数据和其他文件的存储。故选择为C。
