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.
