Consider a system having m of 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 n deadlock will not occur?

The correct option is A 13
Consider a system having m of 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 13 value of n deadlock will not occur.
Consider the peak demand situation of resources (A, B, C)=
(3,4,6).
Total
of max needs < (no. of resource instances + no. of processes)
(3+4+6)<
m+3.
m>10.
Hence m should be eleven or above. Only 13 qualify the criteria.
Deadlockrefers to a specific condition when two
or more processes are each waiting for another to release a resource, or more
than two processes are waiting for resources in a circular chain.
