11. The primary function of the _______ is to translate network addresses into their physical counterparts and decide how to route data from the sender to the receiver. 2 points
20.a. Access Methodology is one type of topology discussed in the chapter. It is based on sharing media through different forms including CSMA/CD and Token Passing. In CSMA/CD the sender listens to see if someone is already “on the line” with the designated carrier. If the data cannot be transmitted the carrier returns a jamming signal in which the sender interprets and the process is repeated after some time. In Token Passing a monitor from client to client. The client with the token is the only one with control of the network. When there is a break in transmission, the token continues being passed along the network. This method works better with larger systems.

b. Logical Topologies are methods of transporting data from one workstation to its destination. In the sequential method, or ring logical topology, the data is passed from workstation to workstation until one recognizes the data as being meant for it. In broadcast method, the data is sent out to the entire network and each node decides if the message was meant for it.
c. Physical Topologies is the physical connections between the workstations. Most often these are in the star layout with a server as the center and workstations branching out from it. There are however the bus (computers in a linear arrangement) and ring (computers joined on both ends creating a loop) layouts with less effectiveness.
