What are some examples of computer hacking?

Just watch sWordfish, die hard 4 or war games. You'll understand what hacking is then... or at least the Hollywood perception. And that's why most people get into hacking anyway, by watching films centered around it. Though in reality, there is a lot less action, all those long weekends partyin will have to become long weekends of fixing networks and programming if you ever plan on getting good at hacking. The most exciting thing you will probably end up doing is crimping RJ45's onto an ethernet every few weeks.
