FireWire is a type of bus standard also known as IEEE 1394. This very fast bus supports data transfer rates of up to 400 Mbps (megabits per second). Because of its high speed, FireWire is often used for transferring video files. Found on most Apple computers, the name FireWire was originally developed and trademarked by Apple computer. Other companies use different names, like “ilink” and “Lynx” to describe their IEEE 1394 ports.
