Sometimes in these cases I just go by exclusion. Just remember one of the two, and the other one automatically becomes "the other". For tun/tap I can actually tell which is which because I use them frequently, but for example you could just remember that tun stands for tunnel (I suppose) so it's for point-to-point connections and hence carries IP (while tap carries ethernet frames and can broadcast, but you don't need to remember this; it's easily deduced by contrast against the former). There can be of course dozens of other ways. Another one is using the words you want to remember to somehow form other words (perhaps funny or in any case easier to remember), which could have a connection with their original meaning. Again, silly example: for tap, you could remember wiretap, where the "wire" part should make you think "ethernet", which is where tap operates (I think this would work in my case; it might not for you, but of course each one of us has his own mental paths and associations). For RSA, you could remember "univeRSAl", which might mean that it is the algorithm you always tell people to use. Etc. etc. Hope the above suggestions make sense to you. Of course, besides the silly examples, the important point is that the best way is to build associations with things that *you* can easily remember.
