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.
如果有用户或应用程序以绑定模式连接(使用共享内存)，操作系统将使用ID和密码对其进行身份验证。
If there are users or applications connecting in bindings mode (using Shared memory), the operating system will authenticate them using an ID and a password.
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.
换句话说，操作系统不会强制您通过锁来共享资源，所以，所有需要该资源的进程都必须协同使用该锁。
In other words, the operating system doesn't enforce the resource sharing through the lock, so all processes that need the resource must cooperate to use the lock.
现在可以指定创建操作系统平台或者SHMMAX参数所允许的最大共享内存段。
You can now specify that segments for shared memory be created as large as your operating system platform or the SHMMAX parameter allows.
可以使用清单1中的命令行选项控制缓存的最大大小，但是请注意，这个最大大小可能受到操作系统共享内存限制的约束
You can control the maximum size of the cache by using the command line option in Listing 1, but note that this maximum size may be constrained by operating system restrictions on shared memory
真正的虚拟化是在2005年的Integrity虚拟机中引入的，这种技术支持分区拥有操作系统的完整副本和共享资源。
Real virtualization was then introduced with Integrity virtual Machines in 2005, allowing partitions to have their own full copy of the operating systems and the sharing of resources.
除了操作系统对段施加的限制之外，没有定义对Domino共享内存增长的限制。
There is no defined limit to the growth of Domino shared memory other than the operating system imposed limit of segments.
注意，一些操作系统设置可能会限制可分配的共享内存量，例如Linux上的SHMMAX通常设置为大约20mb。
Note that there are operating system Settings that can limit the amount of Shared memory that can be allocated — for instance, SHMMAX on Linux is typically set to about 20mb.
操作系统自动地确保在试图通过TCP连接特定端口的多个远程IP地址之间共享资源。
The operating system automatically ensures that resources are shared across multiple remote IP addresses that are attempting to connect through TCP to a specific port.
就像我们在17章和15章看到的那样，多进程不得不用复杂的机制去处理操作系统的共享内存和文件描述符。
Multiple processes have to use complex mechanisms provided by the operating system to share memory and file descriptors, as we will see in Chapters 15 and 17.
基于该系统设计和实现了一个全局共享内存系统，使操作系统充分利用整个系统上的物理内存，减少应用程序的执行时间。
A global Shared memory system is implemented based on the system, and it can allow operating system to use system-wide memory to decrease the execution time of the application.
在实践中，很多用户使用的操作系统仍然是WINDOWS系列，而如何与UNIX系统互联和资源共享是个难题。
In practice, the operating system that many consumer use is still WINDOWS serial, but how to use the UNIX system connect with each other and how to share resource is a problem.
资源共享是操作系统程序和多个用户程序共用系统中的资源。
The sharing of resources is the operating system procedures and procedures for multiple users to share system resources.
操作系统和驱动程序之间的数据通信采用共享内存和异步通知相结合的方式进行。
Data communication of the operating system and the driver selects sharing memory and asynchronous notice unify to carry on.
操作系统和驱动程序之间的数据通信采用共享内存和异步通知相结合的方式进行。
