Unformatted text preview: CIS 3003 – Homework 11 1. A LANs physical topology is not the same as its logical topology. 2. One advantage of a star configuration is that if one cable connection fails, the other connections continue operating. 3. If a LAN was physically wired as a ring, in which cables run between subsequent devices rather than to a central hub, a failure in any cable connection would adversely affect the entire network. 4. In a logical ring topology, data flows sequentially from one computer to the next in an orderly pattern around the ring. 5. In a logical bus configuration, a bus interconnects all computing nodes via a continuous cable. 6. Historically, the two most common access control procedures for shared LAN approaches have been token passing and CSMA/CD. 7. Token passing access method is deterministic. 8. Using the token passing method, each node communicates only during its specified turn. 9. CSMA/CD is a non-deterministic access method. 10. With CSMA/CD, any device may transmit information at any given moment, provided no other devices are already transmitting....
