OS的设计中也包含了防止不同进程中间产生的相互干扰问题。 当然,不是所有的OS都有privileged mode,一些比较简单的电子元器件或者机器人中就不需要privileged mode 注意在这种情况下一个程序错误可能直接导致整个os崩盘。。。 小结 现代操作系统不同功能之间的关系全貌(例子)+早期windows OS设计: linux和windows系统的一...
An operating system is software that enables users to run applications on a computing device. It handles input, output, network connections, storage, resource allocation, and more. Applications can interact directly with hardware, but most are designed for an OS. Early systems in the 1940s-1950...

Operating System Errors There are many ways that an operating system itself can become corrupted or damaged, but these issues are relatively rare. In Windows, the most severe is theOperating System Not Found error messagethat implies an OS can't even be found!
Performance:System calls are optimized for performance, as they are written in low-level languages and are designed to be as simple and efficient as possible. System calls in os provide a standardized interface for applications to interact with the operating system, ensuring the security, stability...
