操作系统

All resources and operation in system disk will not be saved acquiescently after shutting down or restarting operating system. Conversely, default security strategy of user disk is saving operation in this disk.

由于操作系统要求的安全性较高，系统盘默认的安全策略是操作系统不保存用户对系统盘所作的任何操作，而用户数据要求的安全可靠性相对较低，灵活性较高，用户盘默认的安全策略是操作系统保存用户对用户盘所作的任何操作。

At the time OS/2 was introduced in late 1987, the most common personal computers were IBM-compatible computers running the Microsoft Disk Operating System and computers manufactured by Apple Computer Corporation running Apple's system for the Macintosh.

OS/2，或称"第二代操作系统"，是20世纪80年代中期由IBM公司和微软公司为个人计算机开发的一种操作系统。1987年末，OS/2推出时，最常见的个人计算机是运行MS-DOS的IBM兼容机和由苹果计算机公司生产、运行其麦金托什个人计算机操作系统的计算机。

In response, industry analysts believe that Microsoft aware that the Internet has begun to play the role of PC operating systems, coupled with the virtualization technology of the increasingly popular, has more than 20 years of rule the Windows operating system be eliminated only a matter of time, so then launched One called "Midori" operating system project.

对此，行业分析人士认为，微软意识到了互联网已开始扮演PC操作系统的角色，再加上虚拟化技术的日渐盛行，已统治20多年的Windows操作系统被淘汰只是时间问题，因而随之启动了一项名为"Midori"的操作系统项目。

However, it is necessary for us design an architecture which allows subsystems to be merged into an integrated node computer in order to save cost. At the same time, it must be ensured that residual design faults in low criticality subsystem cannot corrupt high criticality subsystem while they cooperate with each other.

为设计高可信的任务关键实时操作系统，探索了基于时间隔离与空间隔离保护机制构建高可信任务关键实时操作系统的新思想，其目的是把设计缺陷所导致的失效影响控制在一个较小的时空范围内，使实时操作系统在其支撑范围内提供尽可能强的可信防范机制，在用户应用程序与系统资源之间进行符合防危策略的调度，防止发生灾难性事故。

And we can also understand OS\\\s fundamental principle more profoundly through studying the source code .
