Task

This assessment aims to develop and gauge student understanding of the key topics covered so far by answering the following questions. Answering these questions will help you build some understanding for the next assessment item as well as for the entire subject. It is expected that answers to the assignment questions be succinct (i.e. precise and concise) with all sources of information fully referenced as per APA referencing style. You have to reference the text book and any additional material you have used in your answers.

Note that the guide for APA referencing is provided in the resources section of Interact site of this subject.

Answers MUST be written in your own words. No marks will be awarded for any answer that contains more than 10% direct quote (referenced or unreferenced). One or two sentence answers will be too short and only receive low marks. Answers longer than 1.5 pages (12 point font, single line spacing) may incur a penalty if too much non-relevant information is stated. For mathematical questions it is expected that you show intermediate steps of your working. Just stating the correct solution will result in low marks, on the other hand if the working is correct and you only made minor mistakes, you will still be awarded marks, even though the final answer is wrong.

Question 1 [3 Marks]

Write functions of each layer of OSI reference model, also differentiate between hardware and software layers. Explain your view; why Network layer of OSI model is called Internet layer in TCP/IP networking model?

Question 2 [5 Marks]

Complete the Hands-On Projects as listed in the Online Lab section of Module 2 from the subject interact site. In order to complete these activities, students should insert screenshots in the assignment document along with a brief informative description of each step taken to complete the project. Marks will be deducted if the description is not provided.

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 address192.168.128.0/20:

1. Use VLSMaddressing,ietheminimumnumberofbitstoincludeallrequired hosts.


2. The gateways are thelastusablehostaddress(es)ofeachsubnet.


3. The printer is the5thusablehostaddressofeachsubnet,exceptfor theWANs.
