Question:

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.

The Correct Option is A

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. \[ \therefore \text{Correct Answer is (A)} \]
