Nennen, skizzieren und erläutern Sie drei verschiedene Netzwerktopologien

1. Point-to-Point/Line topology

8: Nennen, skizzieren und erläutern Sie drei verschiedene Netzwerktopologien

  • -  Direct connection between two nodes physically and logically

  • -  agreement on communication protocol

2. Bus Topology

- physical:
 Shared line between a number of nodes
 concurrent access must be handled
 one failing node can render the bus useless

- logical:
 One-to-many communication (Information sent by one node is transmitted to all

other nodes) 3. Star Topology

- physical:
 All nodes are connected to one "central" node

- logical:
 one node manages communication

4. Ring Topology: - physical:

every node has exactly two connections, first node is connected to last node - logical:

transmission token is passed between nodes
