Valid answers are:

•   A DataSet can represent an entire relational database in memory, complete with tables, relations, and views.
•   A DataSet is designed to work without any continuing connection to the original data source.
•   Data in a DataSet is bulk-loaded, rather than being loaded on demand.
•   There's no concept of cursor types in a DataSet.
•   DataSets have no current record pointer You can use For Each loops to move through the data.
•   You can store many edits in a DataSet, and write them to the original data source in a single operation.
•   Though the DataSet is universal, other objects in ADO.NET come in different versions for different data sources.

The answer is server-side code since code-behind is executed on the server.  However, during the code-behind's execution on the server, it can render client-side code such as JavaScript to be processed in the clients browser.  But just to be clear, code-behind executes on the server, thus making it server-side code.
