2. What is BIG NOSE? Operating System and Networking workbench consisting of Four Ethernet Local Area Networks (LAN) each containing a variety of Operating Systems Software Hardware Client/Server Functionality Easily unconnected from the campus network to ensure no interference with campus-wide network security and service Absolutely NO administrative restraints on any users

3. Why is BIG NOSE Necessary? Computer Science students require absolutely unrestricted access to operating systems and networks if they are to be well trained. Campus laboratories always restrict student access to computer networking and operating system functions. It is the Computer Science student who will, in the future, write the software and administration functions that are out of his or her reach in general purpose laboratories. In order to truly understand the functionality of a network or operating system, one must experiment with it. This includes modifying it and rebuilding it.

4. BIG NOSE Configuration Four Local Area Networks connected in series named: 1. Donovan 2. Larkin 3. Merilan 4. Greenberg Each LAN contains four Hosts named: Donovan – Captain1, Captain2, Captain3, Captain4 Larkin – Captain1, Canal1, Canal2, Canal3 Merilan – Canal1, Voyager1, Voyager2, Voyager3 Greenberg – Voyager1, Yukon1, Yukon2, Yukon3 Captain1, Canal1, and Voyager1 are multi-homed hosts.
