Q 1 Suppose you are installing a new network for a company that is growing rapidly. The current design calls for 28 computers, with expansion to 80 in the next six months. Because of the speed at which the network is expected to grow, you want to make sure that adding new devices in the network and troubleshooting will be as easy as possible. So, considering these factors, which topology you will prefer for this type of network? Give proper reasoning to support your answer. (5 Marks)

Q.2 How does the logical topology differ from the physical topology? Can a single physical topology support multiple logical topologies? Answer with proper reasons. (5 Marks)


Q 3 Suppose you have been asked to put together a proposal for a new computer network of a company. You have been asked to specifically list the advantages to networking. Of the following equipment the company owns, which devices can be shared on a network? (5 Marks)

Choose all that apply:


  1. Keyboard
  2. Mouse
  3. Scanner
  4. Monitor
  5. CD-ROM drives
  6. Light pen
  7. Printer




Note:


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



  • Your answer should be “to the point”.

Muhammad Usman not only scanner and printer

cd room also shared but it not a good practice to share CD ROM of any sytem because every system have a CD Rom by it self... i never c in any large office to doing this kind of practice. u only can c this kind of practice in any small printing and composing center.

1st Solution:-

STAR would be more appropriate as it is good with multiple computers connected in a big network plus it can also perform troubleshooting and new devices can be easily added in this network at any time.
According to me STAR would be more suitable as it is good with many computers connected in a network plus can also perform troubleshooting and new devices can be easily added in the network.

No 2nd Solution:-

The physical describe of devices on a network, each and every LAN has a topology, or the mode that the devices on a network are arranged and how they communicate with each other. The want that the workstations are linked to the network through the real cables that transmit data -- the physical structure of the network -- is called
the physical topology.
The logical topology, is contrast, is the way that the signals act on the network media,
on the way that the data passes through the network from one device to the next without regard to the physical interconnection 
of the devices.

Because multipoint topologies share a ordinary channel, each device needs a way to
identify itself and the device to which it wants to send information. The method used to
categorize senders and receivers is called addressing four types of physical topologies are often
used in computer networking:

1. Star
2. Bus
3. Ring
4. Hybrid

Question 1:                                                                                                                               Marks 15       

 

Assume as a network manager in a company you have to link their different offices in different cities. To connect all the offices as a network and make sure the network is protected from unauthorized use and provide reliable communication, you are required to answer the following questions:

                         

  1. Name the network type which is used according to the given scenario?

 

  1. Which OSI layers deal with error control?     

                               

  1. To ensure unauthorized use of data, it should be encrypted and decrypted during the transmission. Which OSI layer performs encryption and decryption?

 

  1. Which layer in OSI model functions as a link between user support layers and network support layers?

 

  1. What is the effect of Compression in data transmission?

 

Question 2:                                                                                                                               Marks 05       

 

Draw a hybrid topology with a star backbone and three ring networks. You can use any drawing tool to draw the topology and copy paste in assignment file.

 

BEST OF LUCK
