Given below are two statements. Assertion (A): For a dedicated resource like processor, if at the same time more than one process wants to use the resource, then the CPU can be utilized by only one process at a tim E. Reason (R): Due to lack of available resources, conflicts are resolved so as to achieve serializability for dedicated resources.
Show Hint
Dedicated resources are allocated in a controlled manner so that conflicts among processes can be avoided.
Both (A) and (R) are correct and (R) is the correct explanation of (A)
Both (A) and (R) are correct but (R) is not the correct explanation of (A)
(A) is correct but (R) is not correct

The Correct Option isA
Solution and Explanation
Concept:
A dedicated resource is a resource that can be assigned to only one process at a time.
Step 1: Check Assertion.
CPU is a resource. If multiple processes want CPU at the same time, the CPU scheduling mechanism allows execution in an organized manner.
For a dedicated use situation:
\[
\text{Only one process uses the resource at a time.}
\]
So, Assertion is correct.
Step 2: Check Reason.
When resources are limited, conflicts may occur between processes. These conflicts are resolved by scheduling and serializing the access to the resource.
So, Reason is also correct.
Step 3: Check explanation.
The reason explains why only one process can use a dedicated resource at a time.
\[
\therefore \text{Correct Answer is (A)}
\]
