PY365 Week 3 Threaded Discussion

Using examples, outline the benefits and limitations of Intellectual Property Protection.

A number of courts have been faced with infringement claims arising in connection with Internet activities. In fact, most Internet-related disputes arise in the context of domain disputes. Please research the topic of Internet trademark infringement and provide at least one example. What is your opinion related to Internet trademark infringement?

PY360 Week 6 Discussion

Discuss three or more uses of computer simulation. Cite your sources in APA format.

Are we living in a computer simulation?

According to Michael J. Quinn, "Sometimes the effects of a computer error are trivial...At other times computer malfunctions result in a real inconvenience...On a few occasions, failures in a computerized system have even resulted in fatalities." Please provide an example for each of these three possibilities.

 

PY360 Week 5 Discussion

Provide at least two (2) examples of crimes on the Internet that were identified as crimes before the Internet existed. What has their impact been in an online environment?

Define hacker. Discuss how the term was used originally and how it is used now.
