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!
