CCST9015 Questions Will you download a DVD from the Internet if you had a 60 Mbps connection? Why/ Why not?   Will you upload a DVD to the Internet if you had a 60 Mbps connection? Why/Why not?   Company A claims that it can provide you with a 60 Mbps bandwidth for DVD delivery for HK$300 per month …  

•  Is it technically possible? •  Will you buy into it?  

If you do have a 60 Mbps connection to the Internet, how can you use it to improve the lives of the people living below the poverty line?

Plagiarism    

Absolutely ZERO tolerance in plagiarism My unofficial definition: “Any copying and/or stealing of materials and/or ideas from any person other than yourself” is regarded as plagiarism. •  i.e. includes copying work from previous semester, from the Internet, from your classmates, etc.

 

 

 

In the case of an individual assignment, you will automatically get a ZERO mark for the assignment if acts of plagiarism is detected, including, but not limited to homework, project report, project peer-review, and project presentations. In the case of a group work, any act of plagiarism from any member of the group will result in ZERO mark for the entire group, unless such act has been reported by members of the group not involved in such act, in which case only the person(s) involved will receive ZERO mark. In addition, any person involved in act of plagiarism may be subject to further investigation by the relevant University disciplinary units.
