Operating SystemA computer system has 6 tape drives, with *n* processes competing for them. Each process may need 2 tape drives. The maximum value of *n* for which the system is guaranteed to be deadlock free is (i) 6 (ii) 5 (iii) 4 (iv) 320232mOPERATING SYSTEMA system contains six units of resource, and n processes that use the resource. What is the maximum value of n for which the system will be deadlock free if the maximum requirement of each process is 3?20197mOperating SystemDefine deadlock. List four necessary conditions for occurrence of deadlock. A system contains six units of resource, and *n* processes that use the resource. What is the maximum value of *n* for which the system will be deadlock free if the maximum requirement of each process is 3?201914mOPERATING SYSTEMConsider a system consisting of four resources of the same type that are shared by three processes, each of which needs at most two resources. Show that the system is deadlock-free.20227m
