72. Can you explain the difference between an ADO.NET Dataset and an ADO Recordset?
Ans: 1. A DataSet can represent an entire relational database in memory, complete with tables, relations, and views.
2. A DataSet is designed to work without any continuing connection to the original data source.
3. Data in a DataSet is bulk-loaded, rather than being loaded on demand.

75. What security measures exist for .NET Remoting?
Ans: None.
Ans: None.
76. What are channels in .NET Remoting?
Ans: Channels represent the objects that transfer the other serialized objects from one application domain to another and from one computer to another, as well as one process to another on the same box.

77. What are remotable objects in .NET Remoting?
Ans: 1. They can be marshaled across the application domains.
2. You can marshal by value, where a deep copy of the object is created and then passed to the receiver. You can also marshal by reference, where just a reference to an existing object is passed.

78. Do you know the proxy of the server object in .NET Remoting?
Ans: This process is known as marshaling. It handles the communication between real server object and the client object. We can say that It’s a fake copy of the server object that resides on the client side and behaves as if it was the server.
79. Give your idea when deciding to use .NET Remoting or ASP.NET Web Services?
Ans: 1. Remoting is a more efficient communication exchange when you can control both ends of the application involved in the communication process.
2. Web Services provide an open-protocol-based exchange of informaion. Web Services are best when you need to communicate with an external organization or another (non-.NET) technology.
