The term descriptor is kinda ill suited as the name of this article. The term is easily confused with file descriptors and surely a better x86-specific name can be given to this article. --[[User:Sortie|Sortie]] 18:05, 5 July 2013 (CDT) |

Revision as of 09:56, 8 July 2013
In reference to the [Paging] references made on the page: AFAIK (Intel Documentation) there is no relation to Paging in desctiptors.
The P (Present) bit for selectors when 0 can generate a #NP (Segment Not Present), whereas the P (Present) bit in PDE/PTE (page directory/table entries), when 0, can generate a #PF (Page Fault). Forge 17:06, 5 July 2013 (CDT)

Renaming or splitting article
The term descriptor is kinda ill suited as the name of this article. The term is easily confused with file descriptors and surely a better x86-specific name can be given to this article. --Sortie 18:05, 5 July 2013 (CDT)
