List all instances (activities) you can think of in the last 12 months where you were (or may have been) in
violation of U.S. Copyright law. Be specific – exactly what did you do?
Copyright “T/F” Questions
Intellectual Property is an Ancient Principle.
Intellectual Property is recognized worldwide.
Without intellectual property, few people would produce original work.
Intellectual Property is necessary to create incentives for the production of original works.
Weakening intellectual property law would result in substandard literature, art, music, and the like.
Intellectual property follows directly from the notion of physical property.

from the data center to the client/server

from proprietary to commodity systems

direct vs indirect selling
