Scenario: In a LINQ to DataSet query, you encounter the concept of deferred execution. Explain what deferred execution means and provide an example of when it might be advantageous.

Deferred execution means that the execution of the LINQ query is delayed until the results are actually needed. This postponement allows for better performance optimization, especially when dealing with large datasets, as it avoids unnecessary computations until the results are required. For example, when dealing with complex queries or when the query result is not immediately needed, deferred execution can be advantageous in terms of resource utilization.
