That the >plug is in the hardware and the socket on a wire is immaterial. Hehe ... I've given up on using plugs and sockets to describe the electrical form of a connector, I just call them male and female connectors ... >But in this context, we've been describing the thing on the power supply by >form, not function, and calling it a plug. Strictly, I suppose it's a female >plug that plugs into a male socket. I guess the problem here is in the wider English language, a plug is something that fits in a hole. The question is, is the connector itself the 'something' (in which case the plug is on the line) or is the smallest contact in the connector (the thing we use to determine if the connector is male or female) is the 'something' (in which case the plug is on the computer). The inverse argument also applies for the socket. In this case, the purists might argue the second, the wider community (and by the looks of things, myself and Neil) might argue the first for the purpose of general discussion. Of course, we know why power generally comes out of a female connector (or commonly the "socket") and goes into a male connector (or commonly the "plug") - it's because if the power source is switched on without a power sink, an exposed male connector can be accidentally shorted with a simple flat metal object whereas it's a lot harder to short a female connector accidentally (and, for the most part, shorting the power sink isn't as big a deal as shorting the power source). There are exceptions of course - mini-DIN power connectors seem to rely on the fact that the outside sheath is far enough past the pins that it isn't likely to be shorted accidentally (not to say it can't be done accidentally of course) ... >The CPC site lists the bit on the PSU as a plug and the bit that gets plugged >into as a socket. > >There's probably an alt.sex. group just for that... Hehe ... of course, you then get into an argument about if a "jack" connector (as in audio jack or power jack) is male (sorry in advance to all those named Jack on this list!) ... IIRC IEEE Spectrum had a back-page article about that perhaps a year ago which was somewhat amusing ... *looks back* ... gee how I rant on when I've just woken up ... hehe - Raymond >Neil > > > > >************************************************************** >http://libretto.basiclink.com - Libretto mailing list >http://www.silverace.com/libretto/ - Archives > > -------TO UNSUBSCRIBE------- >Reply to any of the list messages.
