FIRE WIRE IEEE 1394

IEEE 1394, High Performance Serial Bus, for connecting devices to your personal computer. FireWire provides a single plug-and-socket connection on which up to 63 devices can be attached with data transfer speeds up to 400 Mbps (megabits per second). The standard describes a serial bus or pathway between one or more peripheral devices and your computer's microprocessor. Many peripheral devices now come equipped to meet IEEE 1394. FireWire and other IEEE 1394 implementations provide:

A simple common plug-in serial connector on the back of your computer and on many different types of peripheral devices:

• A thin serial cable rather than the thicker parallel cable you now use to your printer, for example

• A very high-speed rate of data transfer that will accommodate multimedia applications (100 and

200 megabits per second today; with much higher rates later)

• Hot-plug and Plug and Play capability without disrupting your computer

• The ability to chain devices together in a number of different ways without terminators or complicated set-up requirements

In time, IEEE 1394 implementations are expected to replace and consolidate today's serial and parallel interfaces, including Centronics parallel, RS-232C, and Small Computer System Interface (SCSI). The first products to be introduced with FireWire include digital cameras, digital video disks (DVDs), digital video tapes, digital camcorders, and music systems. Because IEEE 1394 is a peer-to-peer interface, one camcorder can dub to another without being plugged into a computer. With a computer equipped with the socket and bus capability, any device (for example, a video camera) can be plugged in while the computer is running.
