CS601 Data Communication Assignment No 1 Solution & Discussion Due Date:08-11-2012

Q. 1. Different topologies behave differently when a connection fails. You are required to discuss the effect on the network when only one device connection fails in the following cases:  [2 x 6 = 12 Marks]

 

  1. Seven devices are connected through a ring topology.
  2. Six devices are connected through a dual ring topology.
  3. Four devices are connected through a mesh topology.
  4. Twelve devices are connected through a star topology (Note: Do not consider the hub failure).
  5. Fifteen devices are connected through a star topology and only the hub is failed.
  6. Eight devices are connected through a bus topology.

 

Note: Your answer for Q.1 should be in the same order as given in the question statements.

 

Q. 2. Suppose a small company wants to develop a computer network of 18 computers in its main office. Due to limited resources the company wants a network architecture where a single communication medium can be shared among all other nodes. Considering this scenario, you are required to suggest the suitable line configuration and name all the possible ways through which your suggested line configuration can be implemented. [3 Marks]

 

 

Note:

 

  • Assignment should be in your own wordings not copied from Internet, handouts or books.

 

  • Your answer should be “to the point”.

i think in bus topology if a node get failed it doesn’t affect the network.

thanks

Q. 1. Different topologies behave differently when a connection fails. You are required to discuss the effect on the network when only one device connection fails in the following cases: [2 x 6 = 12 Marks]

Seven devices are connected through a ring topology.
Ans: disable all the network
Six devices are connected through a dual ring topology.
Ans: network traffic doesn’t effect
Four devices are connected through a mesh topology.
Ans: network traffic doesn’t effect
Twelve devices are connected through a star topology (Note: Do not consider the hub failure).
Ans: doesn’t affect the network.
Fifteen devices are connected through a star topology and only the hub is failed.
Ans: Network is affected.
Eight devices are connected through a bus topology.
Ans: Network is affected.

Note: Your answer for Q.1 should be in the same order as given in the question statements.

Q. 2. Suppose a small company wants to develop a computer network of 18 computers in its main office. Due to limited resources the company wants a network architecture where a single communication medium can be shared among all other nodes. Considering this scenario, you are required to suggest the suitable line configuration and name all the possible ways through which your suggested line configuration can be implemented. [3 Marks]

Ans:

I suggest Multiple line configuration in this situation.

attique Gud keep it up 

CAN ANY ONE EXPLAIN THE QUESTION NO 2?

Ans:- In the given situation we can use the following line configurations in which a single communication medium can be shared among all communication devices :-
• Bus Topology
• Star topology
• Ring topology
But the most suitable line configuration is bus topology because of the following characteristics
• Reduced cost
• Less amount of cabling
• No need of a central powerful server
• A single communication cable is needed that is shared among all other devices

plz agar ap is ko zara explain kary to acha ho mujy kuch samj ni aye plz plz

Different topologies behave differently when a connection fails. You are required to discuss the effect on the network when only one device connection fails in the following cases:  [2 x 6 = 12 Marks]

 

  1. Seven devices are connected through a ring topology.

    Ans: disable all the network

  1. Six devices are connected through a dual ring topology.

    Ans: network traffic doesn’t effect

  1. Four devices are connected through a mesh topology.

    Ans: network traffic doesn’t effect

  1. Twelve devices are connected through a star topology (Note: Do not consider the hub failure).

      Ans: doesn’t affect the network.

  1. Fifteen devices are connected through a star topology and only the hub is failed.

    Ans: Network is affected.

  1. Eight devices are connected through a bus topology.

    Ans:  Network is affected.

 

Q. 2. Suppose a small company wants to develop a computer network of 18 computers in its main office. Due to limited resources the company wants a network architecture where a single communication medium can be shared among all other nodes. Considering this scenario, you are required to suggest the suitable line configuration and name all the possible ways through which your suggested line configuration can be implemented. [3 Marks]

 (Understanding of question/ not exact answer)

"We have to suggest line configuration and all possible ways to implement line configuration."

First of all line configuration means the layout of the network( the way in which devices are connected to the link.

as required in the question we hv to implement a line configuration in which all devices share a common communication medium.following are topologies in which a central medium is shared: ( In other way we can say that in the given situation we can implement line configuration using the following ways) :-

  • Bus Topology
  • Star Topology
  • Tree topology

2nd question

1st ka last walay ma agar koe mistake ha to plz urgent bta do any 1

in question 2nd i just choose 

  • Bus topology
  • Star topology

Tree topology net working due to 

  1. low cost
  2. easy mantinance
  3. easy to adding n removing nodes
  4. no any effect at fails on any node

syed nashit hmm gud
