Fire Wire

Fire Wire

The IEEE 1394 interface, developed in the late 1980s and early 1990s by Apple as FireWire, is a serial bus interface standard for high-speed communications and isochronous real-time data transfer. The 1394 interface is comparable with USB and often those two technologies are considered together, though USB has more market share. Apple first included FireWire in some of its 1999 models, and most Apple computers since the year 2000 have included FireWire ports, though, as of 2013, nothing beyond the 800 version (IEEE-1394b). The interface is also known by the brand i.LINK (Sony), and Lynx (Texas Instruments). IEEE 1394 replaced parallel SCSI in many applications, because of lower implementation costs and a simplified, more adaptable cabling system. The 1394 standard also defines a backplane interface, though this is not as widely used.

IEEE 1394 is the High-Definition Audio-Video Network Alliance (HANA) standard connection interface for A/V (audio/visual) component communication and control. FireWire is also available in wireless, fiber optic, and coaxial versions using the isochronous protocols.

Wire - Varieties
... Hook-up wire is small-to-medium gauge, solid or stranded, insulated wire, used for making internal connections inside electrical or electronic devices ... Magnet wire is solid wire, usually copper, which, to allow closer winding when making electromagnetic coils, is insulated only with varnish, rather than the thicker plastic or other insulation commonly ... (For further information about copper magnet wire, see Copper wire and cable#Magnet wire (Winding wire).) ...
Fire Wire - Security Issues
... On many implementations, particularly those like PCs and Macs using the popular OHCI, the mapping between the FireWire "Physical Memory Space" and device physical memory is done in hardware, without operating system intervention ... While this enables high-speed and low-latency communication between data sources and sinks without unnecessary copying (such as between a video camera and a software video recording application, or between a disk drive and the application buffers), this can also be a security or media rights-restriction risk if untrustworthy devices are attached to the bus ...

Famous quotes containing the words wire and/or fire:

    God, I am caught in a snare!
    I know not what fine wire is round my throat;
    I only know I let him finger there
    My pulse of life, and let him nose like a stoat
    Who sniffs with joy before he drinks the blood.
    —D.H. (David Herbert)

    A young person is a person with nothing to learn
    One who already knows that ice does not chill and fire does not burn . . .
    It knows it can spend six hours in the sun on its first
    day at the beach without ending up a skinless beet,
    And it knows it can walk barefoot through the barn
    without running a nail in its feet. . . .
    Meanwhile psychologists grow rich
    Writing that the young are ones’ should not
    undermine the self-confidence of which.
    Ogden Nash (1902–1971)
