Steps invloved to solve this assignments
Question-1 Suppose ElecTech is a multinational electronics company which has branches in different countries. Recently it has decided to open its new branch in Pakistan. In the new branch, the company wants to deploy computer networks for its different departments each having 13 computers. Following are key requirements for deploying the computer networks:
1. Finance department wants to use fast speed and highly secure network without involving any intermediate device in place.
2. HR department wants to use centrally managed network.
3. Admin department requires connecting all computers in a linear fashion.
4. Finance, HR and Admin departments want to connect their networks with each other in such a way that the data transmission among these departments should be carried through some Token passing mechanism.
Considering the above mentioned scenario and requirements, you are required to fill the following table by mentioning the most suitable topology and number of links required against each requirement:
Requirements | Most Suitable Topology | Requirements Most Suitable Topology No. of links required |
---|---|---|
1 | ||
2 | ||
3 | ||
4 |
Solution:
Reference See the Page 31-34 (please check it yourself)
formulas tu calculate links for topology;
Here N = number of computers connected on the network
For Mesh topology: Links Calculation formula n(n-1)/2 = 13(13-1)/2 =78
Links required for ring topology = n = 13
Links required for star topology = n = 13
Links required for Bustopology = n-1 = 12
Requirements | Most Suitable Topology | Requirements Most Suitable Topology No. of links required |
---|---|---|
1 | Mesh Topology | 78 |
2 | Star Topology | 13 |
3 | Bus Topology | 12 |
4 | Tree Topology | 13 |
Solution
Reference See the Page 31-34
Links Calculation formula n(n-1)/2
N = number of computers connected on the network
