Sometimes in these cases I just go by exclusion. Just remember one of the |
27 |
two, and the other one automatically becomes "the other". |
28 |
For tun/tap I can actually tell which is which because I use them |
29 |
frequently, but for example you could just remember that tun stands for |
30 |
tunnel (I suppose) so it's for point-to-point connections and hence |
31 |
carries IP (while tap carries ethernet frames and can broadcast, but you |
32 |
don't need to remember this; it's easily deduced by contrast against the |
33 |
former). There can be of course dozens of other ways. Another one is |
34 |
using the words you want to remember to somehow form other words |
35 |
(perhaps funny or in any case easier to remember), which could have a |
36 |
connection with their original meaning. Again, silly example: for tap, |
37 |
you could remember wiretap, where the "wire" part should make you |
38 |
think "ethernet", which is where tap operates (I think this would work |
39 |
in my case; it might not for you, but of course each one of us has his |
40 |
own mental paths and associations). For RSA, you could |
41 |
remember "univeRSAl", which might mean that it is the algorithm you |
42 |
always tell people to use. Etc. etc. |

Hope the above suggestions make sense to you. Of course, besides the |
45 |
silly examples, the important point is that the best way is to build |
46 |
associations with things that *you* can easily remember. |
