Hold and wait  = To ensure that hold and wait never occur in the system we must guarantee. That whenever the process request for a resource, it does not hold and other resource. i) We can process request for a resource to the process that is required for its execution before starting its execution. Problem:- = For eg- If there 3 resources that is required by a process and we have given all the resources before starting execution of the process then there might be a situation that initially we required only two resource and after one hour we want third resource and this will cause starvation for the another process that wants this resource in that waiting time that resource can be allocated to other process and complete there execution.

  Set of processer are waiting for each other in a circular fashion.  For eg= there are 3 processes p0,p1,p2  Such that p0 is waiting for the resource held by process p1 and process p1 is waiting for the resource held by process p2 and further process p2 is waiting for the resource held by p0. Methods of handling deadlock  1 Deadlock Prevention. 2 Deadlock Avoidence. 3 Deadlock Detection and Resolution. Deadlock Prevention. = It ensures that the four condition for resource deadlock do not occur simultaneously. This can be done by following methods: (i) We only use the lock for non-shareable resources and if the resource is shareable then we will not use the lock here. (ii) That ensures in case of shareable resources, multiple process can access it at same time. Problem:- = Here the problem is that we can only do it in case of no-shareable resources like printer we can have use mutual exclusion.

  If a process is holding some resource and request other resource that are required and these resources are not available immediately then the resource that current process is holding are preemptive
