Editing NetBIOS Frames (section)

{{short description|Microsoft Windows networking protocol}}
'''NetBIOS Frames''' ('''NBF''') is a non-[[routable]] [[network layer|network-]] and [[transport layer|transport]]-level data [[communication protocol|protocol]] most commonly used as one of the layers of [[Microsoft Windows]] networking in the 1990s. NBF or [[NetBIOS]] over [[IEEE 802.2]] [[Logical Link Control|LLC]] is used by a number of network operating systems released in the 1990s, such as [[LAN Manager]], [[LAN Server]], [[Windows 3.1x#Windows for Workgroups|Windows for Workgroups]], [[Windows 95]] and [[Windows NT]]. Other protocols, such as NBT ([[NetBIOS over TCP/IP]]), and NBX (NetBIOS-over-[[IPX/SPX]]) also implement the NetBIOS/NetBEUI services over other protocol suites.

The NBF protocol is broadly, but incorrectly, referred to as ''NetBEUI''. This originates from the confusion with NetBIOS Extended User Interface, an [[NetBIOS#NetBEUI|extension to the NetBIOS API]] that was originally developed in conjunction with the NBF protocol; both the protocol and the ''NetBEUI'' [[emulator]] were originally developed to allow NetBIOS programs to run over [[IBM]]'s new [[Token Ring]] network.<ref>{{cite web|url=http://ourworld.compuserve.com/homepages/timothydevans/intro.htm|title=NetBios NetBEUI NBF Networking Introduction|accessdate=2007-07-03 |archiveurl = https://web.archive.org/web/20070207171212/http://ourworld.compuserve.com/homepages/timothydevans/intro.htm <!-- Bot retrieved archive --> |archivedate = 2007-02-07}}</ref> [[Microsoft]] caused this confusion by labelling its NBF protocol implementation ''NetBEUI''. NBF is a protocol and the original NetBEUI was a NetBIOS [[application programming interface]] extension.{{cn|date=June 2023|reason=Cited source doesn't support the alleged controversy that the protocol implemented by NetBIOS emulator over 802.2 would be different between Token Ring and Ethernet networks.}}
