I'm missing embedded systems in this context. If I'm looking for ISO/OSI there is only information about TCP/IP and PC's and so on. What if I use a simple microcontroller and want to comunicate with other hardware on a PCB?
Yes, we need to mention
I²S,
I²C,
Microwire,
Serial Peripheral Interface Bus,
System Management Bus,
1-Wire,
X10 (industry standard) ... please add them to the article. At least the article does mention
EIA-485, which is one of the more popular embedded system interfaces.
I tagged this article for lack of references because the only reference given does not touch upon most of the subject matter in the article and computers, networking, and telecommunications is an area of expertise where it is easy to have misconceptions which, if material is unreferenced, will work their way into WikiPedia. I have 25 years of experience in this field an still find that I suffer from the occasional misconception concerning the details of some subjects. I have discovered some of these misconceptions while looking for references to articles that I wrote on WikiPedia so I am sure that finding references is a Good Thing :-) -- mlewis000 00:56, 20 December 2006 (UTC)
A section about the Physical Layer Signalling (PLS) sublayer was added. That is however only used in 10Base-T Ethernet, and may be moved to that article, or described in a wider context. Different IEEE protocols divide the physical layer into several sublayers. In e.g. 100 Mbps and 1000 Mbps Ethernet versions, the PLS sublayer is replaced by a Physical Coding Sublayer (PCS). See for example the IEEE 802.3a model (page 4 at http://grouper.ieee.org/groups/802/3/ae/public/mar00/booth_1_0300.pdf).
Perhaps someone would like to make a table, with one column for each protocol version, where all sublayers are presented. You may start out from the above pdf file. Mange01 ( talk) 12:37, 14 April 2010 (UTC)
This article incorporates public domain material from Federal Standard 1037C. General Services Administration. Archived from the original on 2022-01-22. says that media access control is handled by the physical layer. Data Link Layer says it is handled there. Data Link Layer has only one reference which does not cover this question. I'm inclined to believe the federal standard. -- Kvng ( talk) 13:45, 29 July 2011 (UTC)
The result of the move request was: Move. Jafeluv ( talk) 17:33, 26 October 2011 (UTC)
– The TCP/IP and OSI layering models are not based on proper names of entities. The layers are discussed here as generic groupings, and compared across the different protocols. Many (possibly most) books have them in lower case; some mixed (uppercase "Physical" and lowercase "layer"). In general, there is little or no evidence for the acceptance or usage of these terms as proper names, even in books that capitalize them by convention (see some preliminary discussion on this at Talk:OSI model. WP style is to capitalize only proper names, not things that others capitalize for other reasons. Dicklyon ( talk) 03:44, 19 October 2011 (UTC)
I've worked on updating case in a few of these articles. Review and more would be appreciated. Dicklyon ( talk) 18:34, 26 October 2011 (UTC)
Thanks for helping, EnOreg. In the process, I found other related bits of over-capitalization to work on, like at Talk:Internet Protocol Suite where I did an RM to downcase that one per typically usage and sources. Also the sublayers in some of these articles need work: Talk:Logical_Link_Control#Requested_move. Dicklyon ( talk) 03:12, 27 October 2011 (UTC)
