1 Network Operating Systems Organizational Communications and Technologies Prithvi N. Rao H. John Heinz III School of Public Policy and Management Carnegie Mellon University

2 Readings High Speed and Wireless LANs(Stallings and van Slyke) Class Notes

3 Objectives List several popular network operating systems Cite features of a network operating system Recognize services provided by NOS List several client/server NOS List several peer-to-peer operating systems

4 Network Operating Systems Fundamental function of network (review) File transfer Remote program execution Virtual terminal service NOS service layers more flexible Common elements of NOS Support for multiple station access Data integrity features (transaction, security) Provide shared access to network resources

5 Network Operating Systems Client/Server Novell Netware Microsoft LanManager Microsoft WindowsNT Banyan Vines Peer-to-peer Novel Netware Light Artisoft Lantastic Appletalk Windows for Workgroups
