GATE - 1993 [Operating System]
Question:
Consider a system having m resources of the same type. These resources are shared by 3 processes A, B and C, which have peak demands of 3, 4 and 6 respectively. For what value of m deadlock will not occur?
|
A |
7 |
|
B |
9 |
|
C |
13, 15 |
|
D |
13 |
|
E |
15 |
Solution:
Option (C) is Correct.
A requires 3, B-4, C-6;
→ If A have 2, B have 3, C have 5 then deadlock will occur i.e., 2+3+5=10.
→ If we have one extra resource then deadlock will not occur i.e., 10+1=11.
→ If we have equal (or) more than 11 resources then deadlock will never occur.
Thank You
