List the 5 network topologies.
|
1. Bus
2. Star 3. Ring 4. Mesh 5. Hybrid |
|
|
Mesh topology description:
|
All Systems are interconnected with the other devices
|
|
|
Ring topology description:
|
All systems are connected through a bus with the ends joined. A token is passed around the ring and stops while a device passes data.
|
|
|
Usual speed of a Ring network?
|
16Mbps
|
|
|
Bus 10Base2 topology description:
|
All devices are tapped into a bus with a BNC 'T' the ends of the cable are terminated with a resistor.
|
|
|
What is the rating of a BNC Terminator for 10Base5 or 10Base2 network?
|
50 Ohm BNC Terminator
|
|
|
What is an advantage of Mesh topology?
|
Very robust. This network functions with redundant links and alternate pathways. Multiple devices could be "down" and the net would still function 24x7hour access.
|
|
|
Disadvantage of Mesh topology?
|
Expensive.
|
|
|
Mesh Topology is used in what situations, primarily?
|
Network Backbones... ties devices together that are mission critical.
WAN links primarily. |
|
|
Star Topology advantages?
|
Price! Speed!
