Answer / Manharan Singh Rajput

"The architecture of ADO.NET revolves around data providers, which provide a common object model for database access independent of the underlying database system. It consists of four key components: Connection (represents the connection to the data source), Command (contains the SQL command or stored procedure to be executed), DataReader (a forward-only, read-only stream that retrieves data from a DataSource one row at a time), and DataAdapter (used for filling DataSets/DataTables with data and updating the DataSource based on changes made in the DataSet)."
