- WAN topologies
LAN topologies - Physical
- Logical
- Describes the possible connections between pairs of networked end-points that can communicate
LAN Topologies(Physical) - Bus
- Star
- Ring
- Switched
- Daisy chains
- Hierarchies
- All networked nodes are interconnected, peer to peer, using a single, open-ended cable
- Both ends of the bus must be terminated with a terminating resistor to prevent signal bounce
Bus topology Advantages of Bus topology - Easy to implement and extend
- Well suited for temporary networks that must be set up in a hurry
- Typically the least cheapest topology to implement
- Failure of one station does not affect others
Disadvantages of Bus topology - Difficult to administer/troubleshoot
- Limited cable length and number of stations
- A cable break can disable the entire network; no redundancy
- Maintenance costs may be higher in the long run
- Performance degrades as additional computers are added
Ring topology - started out as a simple peer-to-peer LAN topology
- Each networked workstation had two connections: one to each of its nearest neighbors
- Data was transmitted unidirectionally around the ring
- Sending and receiving of data takes place by the help of TOKEN
Token Passing - Token contains a piece of information which along with data is sent by the source computer
- This token then passes to next node, which checks if the signal is intended to it
