Deadlocks - Operating System Concepts
7 CHAPTERD eadlocksPractice three examples of Deadlocks that are not related to a computer- System : Two cars crossing a single-lane bridge from opposite directions. A person going down a ladder while another person is climbing upthe ladder. Two trains traveling toward each other on the same that a System is in an unsafe state. Show that it is possible forthe processes to complete their execution without entering a :An unsafe state may not necessarily lead to deadlock , it just means thatwe cannot guarantee that deadlock will not occur. Thus, it is possiblethat a System in an unsafe state may still allow all processes to completewithout deadlock occurring. Consider the situation where a System has12 resources allocated among processesP0,P1,andP2. The resources areallocated according to the following policy:MaxCurrentNeedP01055P1422P2936 Currently there are two resources available.
Allocation[i] is as defined in Section 7.5? Explain your answer. Answer: Yes. The Max vector represents the maximum request a process may make. When calculating the safety algorithm we use the Need matrix, which represents Max — Allocation. Another way to think of this is Max =Need+Allocation. Accordingtothequestion,the Waitingmatrixfulfills
