Question

Sanjeevani is a big group of educational institutions with its head office in Hyderabad. It is planning to set up a new University in Amritsar. The Amritsar University Campus will have four blocks/buildings − ADMIN, ACADEMIC, HOSTEL, SPORTS. You, as a network expert, need to suggest the best network-related solutions for them to resolve the issues/problems mentioned in points (i) to (v), keeping in mind the distances between various blocks / buildings and other given parameters.

Amritsar University Campus

Block to Block distances (in Mtrs.)

FROM	TO	DISTANCE
ADMIN	ACADEMIC	60 M
ADMIN	HOSTEL	160 M
ADMIN	SPORTS	80 M
ACADEMIC	HOSTEL	40 M
ACADEMIC	SPORTS	120 M
HOSTEL	SPORTS	150 M

Distance of Hyderabad Head Office from Amritsar University Campus = 2000 km.

Number of computers in each block is as follows:

ADMIN	25
ACADEMIC	600
HOSTEL	120
SPORTS	50

1. Suggest the most appropriate location of the server inside the Amritsar University Campus. Justify your choice.
2. Draw the cable layout to efficiently connect various blocks within the Amritsar University Campus.
3. Name any two wired media that can be used to connect various computers of a block inside Amritsar Campus.
4. For the academic purpose, the University will provide its own 24 x 7 FM channel within the University Campus. Which communication medium, out of the following, is used by FM?
   1. Radio Waves
   2. Micro Waves
   3. Infrared Waves
5. 
   
   1. The students will be attending a lot of online academic sessions and workshops. These will involve audio-visual communication. Write the full name of the protocol which will be used for such a communication through the internet.
      OR
   2. Where should a repeater be installed in Amritsar University campus to boost the signal between blocks? Justify your answer.

Answer 1

1. ACADEMIC Block ⇒ The server should always be placed in the block with the most computers to reduce network traffic and improve efficiency. The Academic block has 600 computers, significantly more than the others.
2. To minimise cable cost, we use the Shortest Path (Minimal Spanning Tree) layout:
   • ACADEMIC to HOSTEL (40 m)
   • ACADEMIC to ADMIN (60 m)
   • ADMIN to SPORTS (80 m) Total Cable Length: 
3.  Two wired media to connect computers
   1. Twisted Pair Cable (specifically CAT6/Ethernet for connecting computers within a block).
   2. Fibre Optic Cable (best for high-speed connectivity between different blocks).
4. Radio Waves
5. Protocol and Device placement
   1. Full name of the protocol for audio-visual communication: VoIP (Voice Over Internet Protocol).
   2. Between ADMIN and HOSTEL (or any distance exceeding 100m). ⇒ A repeater is required to boost the signal when the distance between two blocks exceeds 100 meters. Since the distance between ADMIN and HOSTEL is 160 meters, a repeater is necessary to prevent signal degradation.
