Deadlocks are able to be described in terms of a directed graph called as a system resource-allocation graph. This graph contains of the following:
Pi Rj indicates that process pi has requested an instance of resource type Rj and is waiting currently for the resource. This is called as the request edge.
Rj Pi indicates that an instance of resource Rj has been allocated to process Pi. This is called as the assignment edge.
