Firewire is developed by apple computer. It is an I/O interface which is known as IEEEE 1394. Its another names are Sony i.Link and Yamha mLAN. However, its technical name is IEEE and we use the most commonly used Apple’s Firewire name.
Firewire have two primary versions named FireWire 400 and FireWire 800. FireWire 400 is also known as IEEE 1394a and FireWire 800 is known as 1394b.
Comparison between FireWire 400 and 800
6 pin FireWire
9 pin FireWire
Firewire 400 uses 6 pin connectors where FireWire 800 uses 9 pin connectors.
FireWire 400 gives a data transfer rate of 400 Mbps where FireWire 800 gives 800 Mbps.
FireWire 400 is known as IEEE 1394a and FireWire 800 known as IEEE 1394b.
6 pin connectors are rectangular with beveled corners where 9 pin connectors are rectangle with square corners.
IEEE 1394a introduced on Macintosh computers and both IEEE 1394a and 1394b support daisy charging.
FireWire is use to boot a computer in Macintosh computers. It works on target disk mode which allows the hard drive to show an external drive on another computer.
FireWire is faster than USB 2.0 because it provides speed up to 800 Mbps where USB 2.0 gives up to 480 Mbps. Moreover, FireWire 400 also gives more speed to read and write data than USB 2.0. FireWire was the popular choice among audio and video professionals when it was not popular as USB.
FireWire (IEEE 1394) is a local serial bus. This Bus is inaugurated by FireWire and originally invented by Apple and Texas Instrument. 1394 is a six-wire cable where there have two pair Clock and Data line as well as one pair power line.
It gives more performance than serial SCSI standard and Ultra-wide SCSI. It is not expensive and easy to connect. 63 devices can connect with an IEEE. We can easily connect Disk, CD-ROM, Optical Disk, DVD ( Digital Video Disk), Digital camera, Tape Drive and other high speed peripheral by 1394.
However, I hope you have got a clear idea about firewire now. But if you have any doubt still now, then don’t forget to throw your query in the comment section bellow.
