Operating System | Methods for Handling Deadloc

Methods for Handling Deadlocks deal the deadlock problem in one of three ways: 1.use a protocol to prevent or avoid deadlocks, ensuring that the system will never enter a deadlocked state. 2.allow the system to enter a deadlocked state, detect it, and recover. 3.ignore the problem altogether and pretend that deadlocks never occur in the system. •The third solution is the one used by most operating systems, including Linux and Windows. •It is then up to the application developer to write programs that handle deadlocks. •To ensure that deadlocks never occur, the system can use either a deadlock prevention or a deadlock-avoidance scheme. •Deadlock prevention provides a set of methods to ensure that at least one of the necessary conditions cannot hold. •Deadlock avoidance requires that the operating system be given additional information in advance concerning which resources a process will request and use during its lifetime.
