Macworld link Terms most know: firewall, spam. Terms most don't know: podcast, RSS, phishing. Their study of 2000 Americans shows that knowing more of these types of terms correlates with being male, having a college degree, being online more frequently, and with being younger. I assume that the results would be the same if they interviewed Internet users in other countries as well. I don't think these results are surprising, and for the most part I don't think it's a problem either. People learn new terms all the time, as the need arises. One worry: Spreading the word about phishing is important (rather than waiting for people to learn about scams by falling victim), and perhaps banks and other official organizations that warn their customers are confusing people by using too many buzzwords.
