Talk:Bus (computing)
From Wikipedia, the free encyclopedia
It's actually a more general term than computing. So this probably means moving. Or at least there needs to be another page, and have them linked together. Hmm. electrical bus perhaps? --drj
Do we really need separate articles for parallel bus, serial bus, internal bus, external bus? Can they be all covered here?
Any chance of some of Serial access, Serial transmission, Serial port merging?
"Buses" or "busses"? In American English at least, the former is the plural of "bus", while the latter is the third-person present tense of "to buss", meaning "to kiss".
Is RS-232 a bus? Surely, it is not, it is strictly point-to-point and hence not a bus in any sense. The same goes for RS-422 and probably a few others too -- Egil
- A bus should connect more than two elements. I agree that RS 232 is not reasonably a "bus" and is never described as such in the EIA standard (at least the Rev C that I have). I'm taking it out. --Wtshymanski 15:57, 15 Apr 2005 (UTC)
Hello! I'm a newbie here and as I didn't find anything in Wikipedia about the controller area network (CAN) bus, I intended to create its entry. But I'm not sure if I should add a link to it in the Computer bus page or in the Electrical bus page. What do you suggest?
By the way, to have an idea about what is the CAN bus, look at: http://www.pcwebopedia.com/TERM/C/controller_area_network.html.
Thanks. -- Akira - Cleber Akira Nakandakare
- An article about CAN (controller area network is a very welcome contribution. It definitely think it should be listed on the Computer bus page, under Examples of External Computer Buses, Serial -- Egil 07:06 21 May 2003 (UTC)
I think that the view of RS-232 not being a bus is conceptual, as someone else suggested about CAT5 nework connections. As a specific example, Centronics parallel connections are supposedly point-to-point, but parallel scanners and parallel ZIP drives (not to menion SCSI-via-parallel and IDE-via-parallel) have been out for years, which can daisy-chain between the computer and a printer. There are multiplexers available to run several independent signals over a serial connection; these are litle different from USB hubs and the like. Scott McNay 01:43, 2004 Feb 26 (UTC)
- The PC-compatible world is full of stunts like that, but desparate work-arounds and expediencies in my opinion don't qualify the IBM PC parallel port as a "bus". It wasn't intended to be used as such, shucks, it wasn't even bidirectional till late in its evolution. --Wtshymanski 16:27, 15 Apr 2005 (UTC)
The following was on the main page in a hidden (html) comment: This is not a technical encyclopedia; this is a general-purpose encyclopedia. Thus, I think we should make an effort to make things understandable by non-techs, if possible, without sacrificing correctness or details. copied across and removed from article page by VampWillow 20:51, 12 Jun 2004 (UTC)
- A diagram is in order. I'll put it on my to-do list unless someone beats me to it. --Wtshymanski 16:27, 15 Apr 2005 (UTC)

[edit] Asynchronous vs synchronous buses
The article says "All the equipment on the bus has to talk at the same speed, and thus shares a single clock." Surely this isn't true, since, for example the Motorola 68000 family implmeented asynchronous buses, where data transfer would vary in speed depending on how fast a peripheral chose to assert the "DTACK" (data transfer acknowledge) signal. --Wtshymanski 16:16, 15 Apr 2005 (UTC)
[edit] Spectra and Multics
RCA Spectra machines did not run Multics...multics was in the GE and the Honeywell camp. Spectra was a pseudo IBM compatible system running operating systems TOS, TDOS and TSOS. I suspect the comments about the BUS could be correct...but for Spectra machines of those that ran Multics?

I agree. But with either answer, it would probably not be the first such system. I don't know what the first would be, but I would guess that Burroughs D825 would be an early example. http://research.microsoft.com/~gbell/Computer_Structures__Readings_and_Examples/00000280.htm Perhaps this is too obscure to be illustrative.

[edit] Three Bus Structure
Do you guys think it'd be worth mentioning the three-bus architecture? As I understand it, it's an important model and is used a lot in computer systems. I could write a little about it if it's a good idea. Haddock420 12:33, 13 January 2006 (UTC)
[edit] Article name
As nobody really calls the subject of this article a "computer bus" (do they?) I propose a name change, to "Bus (computing)" to fit in better with standard Wikipedia naming. Any comments? JulesH 09:50, 13 December 2006 (UTC)
I wholeheartedly agree - I was going to say exactly that. As nobody has responded within 5 days I'm renaming the page and setting the old name to be a redirect. I was going to edit all the links to here, but when I checked there were far too many for that to be viable. Perhaps a bot will sort that out later. Dan Pope 13:17, 18 January 2007 (UTC)
what is a another term for a computer bus? —The preceding unsigned comment was added by 204.29.116.62 (talk)
