5.10 Explain why implementing synchronization primitives by disabling interrupts is not appropriate in a single-processor system if the synchronization primitives are to be used in user-level programs. 如果同步原语要用于用户级程序,请解释为什么在单处理器系统中通过禁用中断来实现同步原语是不合适的。 答: ...

The Process Control Block, also known as the Task Control Block (TCB) or the Control Block, serves as a fundamental building block for process management within the operating system. It plays a pivotal role in process scheduling, synchronization, communication, and resource allocation. Understanding...
