Ans Data Parametrization is done to make the script reusable where the values are not required to be hardcoded.

QUE-10 What is Workbench?
Ans A Workbench in JMeter is a temporary area of storage for the test elements. It also contains non-test elements like HTTP Proxy Server, which can be configured to record scripts via browser in JMeter. Any element placed in the workbench doesn’t get saved after with the test plan’s JMX script.
