WebFeb 18, 2024 · Resource-Allocation Graph. Deadlocks can be described more precisely in terms of a directed graph called a system resource-allocation graph. This graph consists of a set of vertices V and a set of edges E. The set of vertices V is partitioned into two different types of nodes: P - {Pi, Pi,,.., P,,\, the set consisting of all the active ... WebDeadlock Prevention in Operating System Deadlock requires four circumstances to occur. For unshareable single instance resources, a deadlock occurs only when all four conditions occur at the same time. We can prevent deadlock if we prevent these four conditions.
