Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Concurrency allows multiple transactions to execute simultaneously.
This improves utilization of CPU and I/O resources.
Step 1: Understand concurrent execution.
Instead of waiting for one transaction to complete before starting another, multiple transactions can proceed together.
Step 2: Effect on system performance.
Concurrent execution:
• Improves resource utilization
• Reduces idle time
• Allows more transactions per unit time
Step 3: Identify the main objective.
The primary goal is \[ \boxed{\text{Increasing Throughput}} \] which means increasing the number of completed transactions per unit time.
