Which network topology is the easiest to install and requires the least amount of cable?

Question

BlackTom AI · Accepted Answer

Bus topology uses a single central cable (the backbone) to which every device is attached, so installation is straightforward and cable usage is minimal.

1) Relevant knowledge points and concepts
- Bus topology: one continuous backbone cable with devices tapping into it.
- Star topology: each device has a dedicated cable to a central hub/switch.
- Ring topology: devices are connected in a closed loop; each device links to two neighbors.
- Mesh topology: devices are interconnected with many point-to-point links (full mesh uses n(n−1)/2 links).
- Installation effort and cable quantity are determined by the number of separate links and the total cable runs required.

2) Step-by-step reasoning
- Bus: run one main cable along the network area; attach each node with a short tap. The primary run is a single continuous cable (plus short drops).
- Star: run an individual cable from the central hub to each node, so the number of cable runs scales directly with the number of nodes.
- Ring: must provide a link between each node and its neighbor around the loop — effectively n link segments for n nodes.
- Mesh: many point-to-point links; in a full mesh the number of links is n(n−1)/2.

3) Intermediate illustrative calculation (example with n = 6)
- Bus: 1 backbone run + 6 short taps (one long run covers most distance).
- Star: 6 separate runs from hub to nodes (6 runs).
- Ring: 6 links around the loop (6 runs).
- Mesh (full): 6·5/2 = 15 links.
Even comparing segment counts and total wiring effort, bus uses one main run and minimal extra drops, so total cabling and installation work are lower.

4) Why the correct answer is correct
- A single backbone reduces total cable length and simplifies physical layout and connections, making bus topology the easiest to install and the least cable-intensive option.

5) Why other options are incorrect
- Ring topology: needs a loop connecting all nodes (more links than a single backbone).
- Star topology: requires an individual cable from each node to the hub (more runs and centralized equipment).
- Mesh topology: requires many point-to-point links (highest cable usage and complexity).

6) Conclusion
Therefore, the correct answer is bus topology, which matches the provided answer.
