Which topology uses the least cable?
Short answer. Bus, which is why it is the cheapest.
Why is mesh costly?
It needs the most links, so the most cable.
Plus and minus
| Topology | Plus | Minus |
|---|---|---|
| Bus | Cheap | Backbone risk |
| Star | Easy fixes | Hub risk |
| Ring | No clashes | One break |
| Mesh | Reliable | Costly |
Remember
| Cheap means risk |
| Reliable means cost |
The cheapest topology is not the best one. Bus is cheap but risky. Star is easy to fix, but needs its hub. Ring avoids clashes but one break hurts. Mesh is reliable but costly. Remember. Cheap means risk. Reliable means cost.
