FireWire, originally developed by Apple Computer, Inc is a cross platform implementation of the high speed serial data bus –define by the IEEE 1394-1995 [FireWire 400],IEEE 1394a-2000 [FireWire 800] and IEEE 1394b standards-that move large amounts of data between computers and peripheral devices. Its features simplified cabling, hot swapping and transfer speeds of upto 800 megabits per second. FireWire is a high-speed serial input/output (I/O) technology for connecting peripheral devices to a computer or to each other. It is one of the fastest peripheral standards ever developed and now, at 800 megabits per second (Mbps), its even faster .Based on Apple-developed technology, FireWire was adopted in 1995 as an official industry standard (IEEE 1394) for cross-platform peripheral connectivity. By providing a high-bandwidth, easy-to-use I/O technology, FireWire inspired a new generation of consumer electronics devices from many companies, including Canon, Epson, HP, Iomega, JVC, LaCie, Maxtor, Mitsubishi, Matsushita (Panasonic), Pioneer, Samsung, Sony and Texas Instruments. Products such as DV camcorders, portable external disk drives and MP3 players like the Apple iPod would not be as popular as they are today with-out FireWire. FireWire has also been a boon to professional users because of the high-speed connectivity it has brought to audio and video production systems. In 2001, the Academy of Television Arts & Sciences presented Apple with an Emmy award in recognition of the contributions made by FireWire to the television industry. Now FireWire 800, the next generation of FireWire technology, promises to spur the development of more innovative high-performance devices and applications. FireWire800 (an implementation of the IEEE 1394b standard approved in 2002) doubles the throughput of the original technology, dramatically increases the maximum distance of FireWire connections, and supports many new types of cabling. This technology brief describes the advantages of FireWire 800 and some of the applications for which it is ideally suited.
