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? Mesh Topology 2 What is total number of links required in the identified topology for the Hall-1? N(N-1)/2 18(18-1)/2 18(17)/2 306/2 153 3 What is total number of ports being used in the identified topology in the Hall-1? n-1 18-1 17 4 What computer topology is being used in the Hall-2? Start topology 5 Identify the connecting device that is being used in the identified topology for the Hall-2? Hub 6 Which category (geographical wise) of network exists is in Hall-1? Local area network(LAN) 7 Which category (geographical wise) of network exists is in Hall-2? Local area network (LAN) 8 Identify the type of network being created when the networks of both countries are connected with each other for meetings of PMs. Wide area network (WAN) 9 Identify the communication mode which is enabling both the PMs to listen and speak to each other at the same time? Full duplex transmission 10 Which layer’s device will be used to connect the networks of both countries for video conferencing? Session initiation protocol (SIP) Best of Luck!
