Network topologies: bus, star, ring and mesh
Flashcards do conjunto (5)
- 1BUS TOPOLOGYAdvantages:
easy to set up
cheap
Disadvantages:
problems with the back bone can bring the whole network down
limited distance can be covered
many data collisions slow the network down - 2—Advantages:
robust - problems with a connection do not affect the whole network
fewer data collisions than bus so faster
Disadvantages:
needs more expertise to maintain
can be expensive to set up because more building work involved and more network hardware and software needed
- 3—Advantages:
Very fast - no collisions
Disadvantages:
Problems with the backbone can bring the whole network down
Data passes through every node - this makes the network vulnerable to malfunctions
- 4—Data can be transmitted from different devices simultaneously. This topology can withstand high traffic.
2) Even if one of the components fails there is always an alternative present. So data transfer doesn’t get affected.
3) Expansion and modification in topology can be done without disrupting other nodes.
1) There are high chances of redundancy in many of the network connections.
2) Overall cost of this network is way too high as compared to other network topologies.
3) Set-up and maintenance of this topology is very difficult. Even administration of the network is tough.
- 5—It is an extension of Star and bus Topologies, so in networks where these topologies can't be implemented individually for reasons related to scalability, tree topology is the best alternative.
2. Expansion of Network is possible and easy.
3. Here, we divide the whole network into segments (star networks), which can be easily managed and maintained.
4. Error detection and correction is easy.
5. Each segment is provided with dedicated point-to-point wiring to the central hub.
6. If one segment is damaged, other segments are not affected.
1. Because of its basic structure, tree topology, relies heavily on the main bus cable, if it breaks whole network is crippled.
2. As more and more nodes and segments are added, the maintenance becomes difficult.
3. Scalability of the network depends on the type of cable used.
