Consider a hybrid network that combines a star and a ring topology. A central hub H connects directly to computers A, B, C, and D. Additionally, computers D, E, F, G and the hub H are connected in a ring, with each adjacent pair linked by a cable. Each star link is \(5\ \text{m}\) long and each ring link is \(4\ \text{m}\) long. For a pure bus topology connecting the same 12 computers, a single backbone cable of \(30\ \text{m}\) is used together with a \(5\ \text{m}\) drop line from each computer to the backbone. Calculate the total cable length required for the hybrid topology and for the bus topology, and state which topology uses less cable.

Answer Options

A. Hybrid: 40 m, Bus: 90 m, Bus uses less cable
B. Hybrid: 44 m, Bus: 90 m, Hybrid uses less cable
Correct Answer C. Hybrid: 40 m, Bus: 90 m, Hybrid uses less cable
D. Hybrid: 40 m, Bus: 100 m, Hybrid uses less cable
Correct Answer
C
Correct Option:
Hybrid: 40 m, Bus: 90 m, Hybrid uses less cable
