深入浅出信号量机制

Several Ways of Learning Semaphore Mechanism

《操作系统》是高校计算机专业的一门非常重要的专业课程,理论性较强,尤其信号量机制一直是大家公认的学习操作系统的难点之一。学生不好懂,也不愿意学。该文从生活中常见的比较有意思的互斥同步的实例出发,介绍了使用信号量机制解决互斥和同步关系的方法。简单易懂,趣味性较强,寓教于乐,轻轻松松掌握抽象难懂的理论知识。

'Operating system' is very important professional courses to the students of studying computer science in university.It is very theoretical.Especially,semaphore mechanism has been recognized to be one of the difficulties in learning 'Operating system'.It is difficult to understand,and some students are unwilling to learn.In this paper,some examples of mutual exclusion synchronization are introduced.They come from the common life and interesting.These examples are simple and easy to understand.By these examples,it turning easy for students to master abstract and difficult theory in 'Operating system'.
