#Chapter4
#Deadlock
If two or more processes are waiting on happening of some event, which never happen then we say these processes are involved in deadlock and then it is known as deadlock.

#ConditionsForDeadlock are
Mutual exclusion
No preemption
Hold and wait
Circular wait

Mutual exclusion: It means that the resource process using should be used in mutual exclusive way. It (resource) should not be used by more than one process at one time.

No pre-emption: No type/ chance of pre-emption would be there.

Hold and wait: Process P1 is holding R1 resource and waiting for R2 resource while on the other hand process P2 is holding R2 resource and waiting for R1 resource. P1 and P2 should not release any resource, if they do this then deadlock will not happen.

Circular wait: The above example is an example of circular wait, if there is circular wait, than deadlock can occur. Let’s see another example
