Why is PHY capitalized?
[edit]Why is PHY capitalized? It might lead someone to suspect it's an acronym. — Preceding unsigned comment added by 71.82.150.182 (talk • contribs) 03:23, 17 January 2008 (UTC (UTC)
- Because it stand for Physical layer. By definition it is an acronym. —Preceding unsigned comment added by 69.74.48.25 (talk) 17:55, 22 April 2008 (UTC)
- It's an abbreviation, not an acronym. - 99.249.183.96 (talk) 01:12, 5 May 2009 (UTC)
- According to wikipedia's page on acronyms, it's an acronym and abbreviation. 109.192.119.234 (talk) 11:00, 21 June 2013 (UTC)
- If it were an acronym it would be PL surely? In fact this page could really do with an explanation of why it is PHY and not PL. PHysical laYer? That seems stupid. 62.189.28.130 (talk) 11:03, 23 November 2016 (UTC)

- The first place where "PHY" is used in IEEE Std 802-2014 is
media-independent control function: A parallel control plane that provides control functions for different medium access control (MAC) and physical layer (PHY) sublayers and provides a media-independent abstraction to higher layer protocols.
- which doesn't indicate how it's derived. It's probably "PHYsical layer". Guy Harris (talk) 18:34, 23 November 2016 (UTC)
General or Ethernet-specific?
[edit]A PHY typically includes a PCS (Physical Coding Sublayer) and a PMD (Physical Medium Dependent) layer.
Physical Coding Sublayer and Physical Medium Dependent sound quite Ethernet-specific. --Abdull (talk) 19:20, 16 June 2008 (UTC)
There are many kinds of PHY in many ARM processors such as Luminary,ST —Preceding unsigned comment added by 218.98.164.8 (talk) 07:33, 7 December 2008 (UTC)
- IEEE Std 802.11-2012 doesn't mention PCS, but it does have multiple PMDs. Guy Harris (talk) 18:40, 23 November 2016 (UTC)
Pronunciation
[edit]How is PHY pronounced? -- Henriok (talk) 12:45, 6 July 2010 (UTC)
- Same question here. I guess "fɪ" since it's and abbreviation not acronym, on the other hand "Ph. D." is pronounced "piː.eɪtʃˈdi", so maybe the same is true for PHY. I've never heard anyone speaking this word. GL1zdA (talk) 09:25, 22 February 2016 (UTC)
