What is deadlock? How do you avoid it?

Answer Posted / kavya

deadlock is sate in which each of the process is waiting for other process to complete.
this problem can be solved in two ways
1. deadlock prevention
2. deadlock avoidance
deadlock prevention is to make sure that any of the four necessary conditions for deadlock to occur doesn't hold good.
four necessary conditions are
a) mutual exclusion
only one process at a time can use a resource
b) hold and wait
if process require more resources it must hold the allocated resources and wait for the required resources
c) no preemption
none of resources are taken back by operating system until a process releases it
d)circular wait
all the process are waiting for resources in a circular manner
deadlock avoidance:
In this method data related to process like resources allocated , resources needed, arrival time etc are studied and occurance of deadlock is predicted. If deadlock is in safe state then resources are allocated or else they are not .
