.银行家算法

操作系统在若干个并行进程间分配数量一定的共享资源，既要使每个进程均能满足其对资源的要求，使之完成其运行任务，同时又要使整个系统不会产生死锁所采用的方法，即银行家算法。银行家算法是解决资源共享问题的一种算法，是研究如何将有限的资源合理分配给多个进程使用，同时系统又不会发生死锁问题的一种算法。

-. Banker' s algorithm operating system distribution among a number of parallel processes a certain number of shared resources, not only that every process can meet the requirements for resources, so that the task to complete its operation, the same time so that the whole system will not produce deadlock the methods used, the banker' s algorithm. Banker' s algorithm to solve the problem of resource sharing, an algorithm is to study how the rational allocation of limited resources to more than one process, while the system deadlock problem without an algorithm.
