Write a tutorial review paper of about 5000 words on three aspects of Data Communications. The first part will be on Digital Communications, the second part on TCP/IP Networks and the third on network security protocols. The three topics can be related or independent and should either extend that presented in the module or be within the scope of Data Communications but have not been covered in the lecture course.

The Digital Communications aspect should include some relevant simulation and / or analysis using 'MATLAB' or 'Simulink'; details of how the simulation and / or analysis was performed as well as results should be included. A listing of your 'MATLAB' code should be included in an appendix at the end of the paper. You should also include a relevant simulation and analysis for the TCP/IP Networks part. You can optionally include a simulation for the network security protocols aspect.

The paper should be presented in a similar form to that used for some journals, with two columns of 12 point text with headings of 14 bold point text and should be consistent with the following guidelines:
