一个操作系统负责决定哪一个任务在给定的时间将使用处理器，并且控制对共享资源的访问。
The operating system is responsible for deciding which task should be using the processor at a given time and for controlling access to Shared resources.
使用者对操作系统、硬件和软件的控制能力水平。
How much control the consumer has over the operating systems, hardware, and software.
你写的操作系统是你自己的，你自己拥有对它最终的控制，而限制你的可能就是只有天空了------Albert：也就是说，几乎是没什么限制你对它的控制。
Your OS is exactly that - yours. You have ultimate control, and the sky is the limit!
对于云交付模型，使用者对部署的应用程序、操作系统、硬件、软件、存储和网络的控制能力不同，这会影响云安全策略。
It is influenced by how much control a consumer can have over deployed applications, operating systems, hardware, software, storage and networking for a cloud delivery model.
随着对操作系统安全性的深入研究，将会引入新的访问控制方法。
New access-control methods will also be introduced as research into operating system security continues.
操作系统调度程序决定哪个线程获得对互斥锁的控制权—通常，等待时间最长的读线程先读取数据。
The operating system scheduler determines which thread gets control of the mutex next-typically, the reader thread that has waited the longest gets to read the data first.
操作系统可以使用虚拟控制台作为各种处理工作(如安装工作、对崩溃故障进行的恢复工作，以及执行启动相关的操作)的控制台。
The virtual console is used by the operating system as a console for various processes, such as installations, recovery from crashes, and performing boot-related operations.
当操作系统检测到一个线程空闲时，把对硬件的控制权交还给系统管理程序，这会使线程进入 nap模式。
The way it works is that the OS detects when a thread is idle and then gives control of the hardware back to the hypervisor, which puts the thread into nap mode.
一旦Flash悄无声息的进入iphone操作系统，苹果公司对顾客的控制力就会被大大削弱。
Were Flash ever to find its way in through the back door to the iPhone operating system, Apple’s armlock on its customers would be severely weakened.
在我们对Linux系统进行探索的过程中，你还会注意到操作系统的很多属性是由shell脚本控制的---在Linux系统中，是不存在任何秘密的。
You will also notice during our adventure that many features of the operating system are controlled by shell scripts. In Linux, there are no secrets!
注意，容器存储在常规操作系统文件中，对加密密钥的访问受该文件上的ACL控制。
Note that the container is stored in a regular operating system file and access to the encryption key is being regulated by the ACLs on the file.
现阶段对操作系统的强制访问控制框架的正确性验证的研究主要集中于对授权钩子放置的验证。
Current researches on correctness verification for the mandatory access control framework of operating systems mainly focus on authorization hooks placement verification.
最后，集成控制器所有模块，建立实验平台，对整个控制器进行实验研究，从而验证控制器硬件电路及嵌入式控制软件、嵌入式操作系统的有效性。
At last, integrate all module of controller, set up experiment platform, perform experiment on entire controller, prove validity of controller hardware, embedded software and embedded system.
