1. Absolutely none. Just the shear amount of time it takes to perform the simplest of hacks do not relate well to the time constrained formats of media.
2. The glossary of terms is right here on this website. Review some of the technical articles.
3. Mission Impossible, Die Hard, etc.. forget you ever saw any of them. The Goth Chic from the TV Show NCIS occasionally does a few realistic things. I stress occasionally. What they did in "The Italian Job" is doable, messing with traffic signals and getting traffic camera video feeds.
Actual criminal, for profit hacking is more along the lines of: Identity theft, Credit Card theft (cc info trades at pennies or less per card # and is usually only sold in bulk), Fraudelent goods and services, various scams and phishing attempts (fake paypal login sites).. for the most part - criminal hacking activity is aimed at individuals, less computer literate types and ripping them off.
There are cases in some countries where criminal organizations use DDoS as a blackmail threat, basically modern version of sending a few thugs to your store and burning a photo of it, then saying you need protection. Pay up or DDoS!
Criminals don't want to get caught, they want to make money. So they don't do the stupid shit. Hacks against banks, corporations and governments are either done by other governments (the "chackers") or by hacktivists looking to make a socio-political statement, or by a small handful of ego driven hackers who want to make their bones and be considered elite and get famous.
