Introduction to Computer Networks — Question 3
Back to all questions"Learn Together" is an educational NGO. It is setting up its new campus at Jabalpur for its web based activities. The campus has 4 compounds as shown in the adjacent diagram.
Center to center distances between various Compounds as per architectural drawings (in metres) is as follows :
| Main Compound to Resource Compound | 110 m |
| Main Compound to Training Compound | 115 m |
| Main Compound to Finance Compound | 35 m |
| Resource Compound to Training Compound | 25 m |
| Resource Compound to Finance Compound | 135 m |
| Training Compound to Finance Compound | 100 m |
Expected Number of Computers in each Compound is as follows :
| Main Compound | 5 |
| Resource Compound | 15 |
| Training Compound | 150 |
| Accounts Compound | 20 |
(a) Suggest a cable layout of connections between the compounds.
(b) Suggest the placement of the following devices with justification :
(i) Repeater
(ii) Hub/Switch
(a) The cable layout for these compounds is given below:
Main compound - Resource compound - Training compound - Finance compound
(b)
(i) A repeater should be placed between the Resource Compound and the Finance Compound due to the 135-meter distance, as it is used to regenerate and amplify signals to cover longer distances without losing quality.
(ii) A hub or switch connects multiple devices within a compound, allowing them to communicate with each other and the broader network. So, there should be one hub per compound.
