    Assignment

    Scenario:

    Suppose Prime Ministers (PMs) of two countries (ABC and XYZ) are holding an important meeting through video conferencing. The native languages of both countries are different; however, both the PMs have agreed upon to use English language for discussion. There are two meeting Halls (Hall-1 and Hall-2) in PM house of ABC country, both having different computer networks. Hall-1 has a computer network of 18 computers where each computer is directly connected to other computer in the network whereas Hall-2 has 8 computers connected with each other through a self-deciding central device to forward data only to intended destination, and the same hall has been used for the meeting of the PMs. Both the halls are connected with each other through an intermediary networking device. Meeting is being held in a smooth flow where each PM can listen and speak to each other at the same time.
    After carefully reading the above scenario, give the answer of each of the question given in the following table:

    S. No. Question Answer
    1 Which type of topology is used in the Hall-1?
    2 What is total number of links required in the identified topology for the Hall-1?
    3 What is total number of ports being used in the identified topology in the Hall-1?
    4 What computer topology is being used in the Hall-2?
    5 Identify the connecting device that is being used in the identified topology for the Hall-2?
    6 Which category (geographical wise) of network exists is in Hall-1?
    7 Which category (geographical wise) of network exists is in Hall-2?
    8 Identify the type of network being created when the networks of both countries are connected with each other for meetings of PMs.
    9 Identify the communication mode which is enabling both the PMs to listen and speak to each other at the same time?
    10 Which layer’s device will be used to connect the networks of both countries for video conferencing?

    Best of Luck!

    Question No. 1

    Scenario

    “Global Consultants” is a consultancy company in Lahore. A couple of days ago, they have decided to open another office in Islamabad. In the new office, they want to establish a computer network for different departments. Following are the department details:

    1. In the “Marketing department” there will be 9 computers that are interconnected with each other to provide efficient communication among them.
    2. In the “Admin department” there will be 5 computers that are connected via a central hub.
      At the end of the day, the admin department of the Islamabad office will pass all the data to a secure main server in Lahore.

    After carefully reading the above scenario, write down the answer of each of the questions given in the following table:

    Questions: Answer:
    Identify the topology that will be used in the “Admin Department”.
    Identify the topology that will be used in the “Marketing department” department.
    Number of links that will be required for the identified topology of “Marketing department”?
    Which type of computer network (LAN or WAN) will be designed within the “Admin department”?
    Number of links that will be required for the identified topology of “Admin Department”?
    Which TCP/IP layer will be responsible for passing the data to the main server in Lahore?

    Question No. 2

    @zaasmi said in CS601 Assignment 1 Solution and Discussion:

    What is total number of ports being used in the identified topology in the Hall-1?
    17

    Formula to find out total number of ports being used in the identified topology?

    =n-1
    Where n is 18
    =18-1
    =17 ports being used in the identified topology

    2
    What is total number of links required in the identified topology for the Hall-1?
    153

    Formula to find out total number of links required:
    =N(n-1)/2
    =18(18-1)/2
    =18(17)/2
    =306/2
    =153 Links Required
