# CS601 Data Communication Assignment#01 Solution Spring 2011

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 schoolbuilding, which topology you will

Hey, you are wrong about Mesh Topology

correct it

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?
Mesh Tepology:

Ring topology:

Star topology:

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.
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.

anything that physically connects two adjacent nodes

e.g: cables, wires etc

AS DEFINED IN LECTURE HANDOUT 2

CS601's IDEA SOLUTION is wrong because it contain N(N-1) for mesh topology while its formula is {N(N-1)}/2
