What are the methods for handling deadlocks?
The technique for handling the deadlocks are:
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.

What are a safe state and an unsafe state? Answer: A state is safe if the system can allocate resources to every process in some order and still avoid a deadlock. A system is
How can the deadlock be prevented? To evade deadlocks first we will have to obtain the information about how resources are to be requested. And as well we should make sure that
