In general, I think it is like this: * Undergraduate (BS / BA - College) * Graduate (Masters, PhD) * Postgraduate (This can be ambiguous. It could mean, "after graduation" which means the same as "graduate" above. It could also mean post-graduate work, which could mean you already have a PhD and you're doing further research "post-doctorate research") http://en.wikipedia.org/wiki/Postgraduate_education

From what I know, there are many angel investors in the US. The highest concentrations of angel investors are in Silicon Valley / San Francisco, and New York City. There are many cities with strong startup ecosystems. The best website I can think of for you is Angel List. http://www.angel.co Many startup companies create profiles of themselves there and are able to meet angel investors through the website. In fact, I'd say almost every (?) startup company that is raising money has probably created a profile on Angel List. I would also look into incubators as well, and see if your company would be a good fit. Some of the more famous incubators are Y Combinator (http://ycombinator.com/) and Techstars (http://techstars.com). I hope that's a good start for you. Good luck with your startup.

As mentioned earlier, prevent and deter can sometimes mean the same thing. Deter is often used when the other party has a choice. It generally implies threatening to take an action in response. The police can deter a bad person from breaking the law. (The police are threatening to put someone in jail / hurt them.) Nuclear deterrence is based on mutually assured destruction. (You are deterring a country from using a nuclear weapon.) Prevent can be used more generally -- the thing that is happening may not be a person or organization. Prevention implies preparation. The goalie's job is to prevent the ball from going in the goal. (You can't deter a ball.) Locking your doors can prevent crime. Using a spellchecker can prevent typing mistakes. Wearing a condom can prevent disease transmission.
