FireWire also known as iLink, IEEE1394, or DV cable is a predominant high speed interface which provides peer to peer device connections for digital transmission of video, audio and data between computers and consumer devices such as printers, scanners camcorders, external hard drives and up to 60 other devices
This featured 6-Pin to 4-Pin Firewire cable features the 6-pin and 4-pin Firewire 400Mb/s which is for older devices however it is limited Firewire rate of 400Mb/s
Firewire provides two types of data transfer: Asynchronous and Isochronous.
Asynchronous is for traditional load-and-store applications where data transfer can be initiated and an application interrupted as a given amount of data arrives in a buffer.
Isochronous data transfer ensures that data flows at a pre-set rate so that an application can handle it in a timed way so you can chain devices together in a number of different ways without terminators or complicated set-up requirements. For multimedia applications, this kind of data transfer reduces the need for buffering and helps ensure a continuous presentation for the viewer.
