The topology I would recommend for the Surfing Shoppe Lab is the Star topology. The seven computers would connected via a centralized device called a switch. Since the star topology has a central connection point, this design is more flexible than a ring or bus topology which requires every node to be directly connected to one another node or utilize a main Ethernet cable or coaxial cable path. Every node within a star network is only directly connected to a hub, switch or router using Ethernet cable. The five researchers would have access to the printer networked via the switch in the main room. During times when the researchers need to remote access the specialized lab computers, the Session Layer won’t be disrupted from other computers that are shut down for the night or have lost connectivity. Protocols in the Session layer coordinate and maintain communications between two nodes on the network (Dean, 2012). Troubleshooting is less painstaking and the entire network does falter should one or more nodes lose connectivity.

1. Unit 3 review questions:

a) The Bus physical topology consists of a single cable that connects all nodes on a network without intervening connectivity devices. p. 199 b) A (n) serial backbone is the simplest kind of backbone. p. 205 c) Fast Ethernet operates at 100Base-T. p. 215

d) Switching is a component of a network’s logical topology that determines how connections are created between nodes. p. 209 e) One thing all Ethernet networks have in common is their access method, known as CSMA/CD (Carrier Sense Multiple Access with Collision Detection). p. 211
