Assignment Question
Question:                                                                                                                                   Marks 15      Suppose a company hires you as network manager and you have to setup their small office as first task that has 10 computers, 2 printers and 1 scanner. To connect all the computers and peripheral devices as a network, you are required to answer the following questions: i)                    Which topology do you think will be feasible in such case? Explain with proper reasoning (1-2 lines).                                                                                                                       (5) ii)                  If Mesh topology is followed then how many number of links and ports are required? (Calculation is necessary to show)                                                                                 (5)                                                               iii)                To which category does the given network belong to?                                                  (2) iv)       Which mode of communication (simplex, half duplex, full duplex) is suitable when a             computer communicates to a printer for printing? Also give one more example of that mode.                                                                                                                               (3)  Solution i)        Which topology do you think will be feasible in such case? Explain with proper reasoning (1-2 lines).                                                                                                                     Ans: Mesh topologies are use in this case.  Mesh topology is only one topology are use in which all devices in the network are interconnected to each other. ii)       If Mesh topology is followed then how many number of links and ports are required? (Calculation is necessary to show)                                                                                      Ans: 1st number of nodes Formula: n (n-1)/2 n= Total number of devices =13(13-1)/2 =13(12)/2 =78   2nd number of ports Formula: n-1 =13-1 =12                                                    iii)     To which category does the given network belong to?                                                        Ans:    LAN (Local Area Network) iv)       Which mode of communication (simplex, half duplex, full duplex) is suitable when a             computer communicates to a printer for printing? Also give one more example of that mode.                                                                                                                               Ans: Simplex:                      In simplex data can travel only one direction. Example: CPU to Monitor
