Other Components: Databricks also has other components like Databricks SQL and various developer tools, each with its versioning.

You can usually find the exact version of a specific component in your Databricks environment in the interface or by running particular commands within a notebook or cluster. For example, to get the Spark version, you can run the Spark. version in a PySpark notebook.
