Detailed Explanation: Computer-based training (CBT) generally has a lower cost per trainee compared to traditional in-person training because it reduces travel, instructor fees, and classroom overhead. CBT can also reach a large audience simultaneously and provides the flexibility of self-paced learning, which is often more efficient. As per the BoK, cost-effectiveness and flexibility are major advantages of CBT over traditional methods, especially when training needs to be scalable across large or geographically dispersed groups.
