To expand on the pedanticness: The letter in the D-subminiature line (aside: they really didn’t anticipate how small connectors were going to become) refers to the shell size (A through E, though not in size order). “DB” is frequently used colloquially as a prefix for any size in the line. There’s also some interesting variants like the DB13W3, which is a B-size shell containing 10 ordinary pins plus 3 coax connectors. RJ11/RJ45 refer to the connectors and the way they’re wired, together. For example, RJ14 is the same 6p connector as RJ11 but wired to support two phone lines instead of just one, and the same 8p8c connector we’d use for Ethernet but wired for 4 phone lines would be an RJ61. |
