    The document contains three questions. Question 1 asks to define the functions of each OSI layer and differentiate between hardware and software layers, and explain why the Network layer in OSI is called the Internet layer in TCP/IP. Question 2 provides instructions for completing hands-on projects from the online lab on subnetting. It lists three projects and says to include screenshots and descriptions. Question 3 provides a case study task where a company needs to subnet their network address using VLSM. It includes a network diagram and table to complete with subnet information.

    Question 3 Case study task [7 Marks]

    Advanced Digital Computer Company needs to subnet their allocated network address 192.168.128.0/20 for their corporate network,
    given in the diagram below (Figure 1).

    Figure 1: Network Diagram

     
    Complete the table below according to the following requirements using the original network address 192.168.128.0/20:
    1. Use VLSM addressing, ie the minimum number of bits to include all required hosts.
    2. The gateways are the last usable host address(es) of each subnet.
    3. The printer is the 5th usable host address of each subnet, except for the WANs.
