'''Open Host Controller Interface''' ('''OHCI''')<ref>https://thefight.pl/t/ohci_11.pdf </ref> is an [[open standard]].

When applied to an [[IEEE 1394]] (also known as [[FireWire]]; [[i.LINK]] or '''Lynx''') card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern [[operating system]]s. Because the card has a standard OHCI interface, the OS does not need to know in advance exactly who makes the card or how it works; it can safely assume that the card understands the set of well-defined commands that are defined in the standard [[protocol (computing)|protocol]].
