Question 1: [5]
For six devices in a network, what is the number of cable links required for a mesh, ring, and star and bus topology?
Question 2: [5]
Draw a hybrid topology with a ring backbone connecting two bus backbones each bus backbone connecting three star networks.
Question 3: [5]
Suppose we want to build a small network in school building, which topology you will prefer and why? Explain your answer with solid reasons.
Solution:
Answer Question#1
Mesh Topology = 30 Cables
Ring Topology = 6 Cables
Star Topology = 5 Cables
Bus Topology = 7 Cables
Mesh Topology
n=6
n(n-1)
Star topology contain of 7 devices. 7th hub device.. but in this question, just asked for 6 devices, so for 6 devices 5 cables..
Bus topology have 6 links but cables are 7, 7th cable straight.
Question 3: [5]
Suppose we want to build a small network in school building, which topology you will prefer and why? Explain your answer with solid reasons.
Answer: For school network we will prefer the Star topology because it is efficient and fast. Lets see why we are preferring this topology in our school.
Explanation:
1. Easy to install
2. Easy to maintain as compare to other topologies
3. If we want to install a system it will take only 1 minute
4. Not costly as compare to other topologies
5. If a system is down our network will not diatribe as compare to bus and star topologies.
