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.
.
21 b. slows down

22. The figure below is a description of a _______________________ topology. [3 points]







23. a. It is a 3-byte token.

24. c. A hub failure cannot disable a LAN segment

25. The figure below describes a ________________________________ topology. [2 poin

26. a. Business
1) IP convergence by building a high-speed ATM network designed to handle data, voice, and video.
2) Next year GPB will add voice to its network. GPB will add a Mitel SX200 PBX which will connect its voice system to its membership server.
b. Application
1) Microsoft Office, Oracle database.
2) Real Networks RealVideo server, online video editing and exchange.
c. Data
1) data, voice and video
d. Network
1) They decided that ATM was the only technology that would let GPB send voice and video on the network over which all of its data is running. It was best suited to handle multiple protocols and highspeed multimedia applications.
2) In desktop application it is indeed rare.
e. Technology
1) They offered products at 1/3 list, and Madge was only major player supporting Novell’s IPX protocol.
2) 180 ATM workstations.
3) ATMs multiprotocol support allow it to run IPX as well as other applicable protocols.
