IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony and Panasonic.

The IEEE 1394 interface is an electronic standard that is used to connect computers. It includes a plug-and-socket connection with a serial bus interface. Up to 63 devices may be connected at the same time with (relatively) high data transfer speeds.

IEEE-1394 is a communication technology that was developed by Apple® in the early 1990s, at about the same time as USB. The original IEEE-1394 standard is known as FireWire, IEEE-1394a, DV or as i.Link® (Sony®'s implementation of the standard).

Also known as the IEEE 1394 High-Performance Serial Bus, FireWire is a serial transmission specification proposed by Apple for connecting high-speed peripherals to computers at speeds of up to 393 Mbps.

IEEE-1394 (FIREWIRE) FireWire is a high-speed serial communication standard defined by IEEE 1394. It was originally designated by Apple, where the name “FireWire” came from. Sometimes it has also been referred to as iLINK (a Sony branding initiative).
