Discuss here about the solution of Assignment no 3....

Assignment Scenario:
Suppose that XYZ Pvt. Ltd is an IT vendor and Service Provider company located in ISLAMABAD. There are five offices of this company; Office A, Office B, Office C, Office D and Office E in the city at different locations.  These offices work together as a network to provide IT products and IT services to customers on their demands.
These offices are connected together through a certain network topology that allows them to communicate with each other through a central node.  For example, Office A (node 1) sends some information regarding a certain product to Office E (node 5) which is 30 Km away from Office A.  This information is received first at central node which is Office C from where information is forwarded (transmitted) to the requested Node Office E. Likewise all the nodes communicate to each other through Office C.

Based on the given scenario, you are required to answer the following questions.



Question No. 1 =2 marks                                                                                                               
In your opinion, which network topology is being used in order to fulfill the communication needs of the Offices (A, B, C, D and E) in the given scenario?    
 
Question No.2=4 marks


After suggesting the correct topology for the given scenario , you have to highlight
·1    Two benefits of using the suggested topology
·2    Two possible problems faced by all offices in exchange of information (communication)

Question No.3 =4marks

You are required to draw network topology diagram for the given scenario. You can use rectangle for nodes and arrows for communication in the diagram.

Question No 1:                                                                                                                           Marks 10

 

Assignment Scenario:

Suppose that XYZ Pvt. Ltd is an IT vendor and Service Provider company located in ISLAMABAD. There are five offices of this company; Office A, Office B, Office C, Office D and Office E in the city at different locations.  These offices work together as a network to provide IT products and IT services to customers on their demands.

These offices are connected together through a certain network topology that allows them to communicate with each other through a central node.  For example, Office A (node 1) sends some information regarding a certain product to Office E (node 5) which is 30 Km away from Office A.  This information is received first at central node which is Office C from where information is forwarded (transmitted) to the requested Node Office E. Likewise all the nodes communicate to each other through Office C.

 

Based on the given scenario, you are required to answer the following questions.

 

 

 

Question No. 1                                                                                                                             2 Marks

                                                                                                                             

In your opinion, which network topology is being used in order to fulfill the communication needs of the Offices (A, B, C, D and E) in the given scenario?   

Solution: According to the given scenario Star topology is used because only central hub is used to communicate with each other through a central node!

 

Question No.2                                                                                                                              4 Marks

 

After suggesting the correct topology for the given scenario , you have to highlight

  • Two benefits of using the suggested topology
  • Two possible problems faced by all offices in exchange of information (communication)

Solution :

Benefits of using the Star topology

1)  Easy to connect new nodes or devices. In star topology new nodes can be added easily without affecting rest of the network. Similarly components can also be removed easily.
2)  Centralized management. It helps in monitoring the network.
3)  Failure of one node or link doesn’t affect the rest of network. At the same time its easy to detect the failure and troubleshoot it

 

Two possible problems faced by all offices in exchange of information (communication)

 

1)  Too much dependency on central device has its own drawbacks. If it fails whole network goes down.
2)  The use of hub, a router or a switch as central device increases the overall cost of the network.
3)   Performance and as well number of nodes which can be added in such topology is depended on capacity of central device.

 

Question No.3                                                                                                                              4 Marks

 

You are required to draw network topology diagram for the given scenario. You can use rectangle for nodes and arrows for communication in the diagram.

Solution:

 

 

thank you Tariq sir for the solution,,,

Dear Students Don’t wait for solution post your problems here and discuss ... after discussion a perfect solution will come in a result. So, Start it now, replies here give your comments according to your knowledge and understandings....


 

Assignment Scenario:

Suppose that XYZ Pvt. Ltd is an IT vendor and Service Provider company located in ISLAMABAD. There are five offices of this company; Office A, Office B, Office C, Office D and Office E in the city at different locations.  These offices work together as a network to provide IT products and IT services to customers on their demands.

These offices are connected together through a certain network topology that allows them to communicate with each other through a central node.  For example, Office A (node 1) sends some information regarding a certain product to Office E (node 5) which is 30 Km away from Office A.  This information is received first at central node which is Office C from where information is forwarded (transmitted) to the requested Node Office E. Likewise all the nodes communicate to each other through Office C.

 

Based on the given scenario, you are required to answer the following questions.

 

Q1: In your opinion, which network topology is being used in order to fulfill the communication needs of the Offices (A, B, C, D and E) in the given scenario?   

Q2: After suggesting the correct topology for the given scenario , you have to highlight

  • Two benefits of using the suggested topology
  • Two possible problems faced by all offices in exchange of information (communication)

Q3: You are required to draw network topology diagram for the given scenario. You can use rectangle for nodes and arrows for communication in the diagram.

 

Solution;-

 

Q1:-

Answer:   According to the above mentioned scenario the “Star Topology is used” as

mentioned when “Office A” wants to send a message to “Office E” the message is first received at ‘Office C” which is central point and then the message is transmitted to “Office E” thus we can consider “Office C” as server.

 

Q2:-

Answer:  Two benefits for using this type of topology (star) are as under:-

  • If any of the nodes goes down the rest of the network is not affected.
  • Good security no one can interact with each other without going through the main “Office C” (supposed as server or central unit)

 

Two disadvantages of the star topology are as under:-

  • Expensive network due to amount of cable used in it every computer has its own cable to be connected to Central point/ server
  • If the main central Server clashes or stop working then no body will be able to send message to others or use files and access the network

 

Q3:-

Office  B

 

Office  E

 

Office  D

 

Office  C

 

Office  A

 

Answer:  The diagram for the star topology is as following
