To make sure that deadlocks never occur, the system is able to use a deadlock prevention or deadlock prevention scheme. Deadlock prevention supplies a set of methods for ensuring that at least one of the necessary conditions cannot hold. Deadlock avoidance needs that the operating should be given advance information concerning with resources a process will request and use during its lifetime. If a system makes sure that a deadlock will never occur nor provides a mechanism for deadlock recovery and detection then we will reach a situation of deadlock but won't recognize what happened. To hold off the deadlock condition away from the system we must keep track of the resources each time, thus we will get the number of resources that are free and the resources that are being used and being requested.
