deadlock and starvation

Question

Which of the following statement is correct?

S1: If deadlock occurs then starvation occurs.

S2: if deadlock occurs then starvation do not occur?

Comments

both false

If deadlock occurs, starvation may or maynot occur, vice versa

Answer 1

Deadlock: is when all the processes do not get access to resources because every process is waiting for some another process and there is cycle.

Starvation: is when a low priority process does not get access to the resources it needs because there is a high priority process accessing the resources. The entire system of processes hasn't come to halt in this case.

---

Since, only low priority process do not have access to resources in starvation, while in deadlock no process has access to the resources they need therefore deadlock is an extreme case of starvation with the criteria of extremeness being the total count of process not getting access to the resource.

---

Deadlock and starvation are related as both are the cases of process not having access to resource.

as a ANSWER -i will select S1

Answer 2

every deadlock is a starvation'

but every starvation is not a deadlock

 

so i ,ll go with s1
