There are many different versions of both.
The Related Link explains something of this interface and gives a number of other useful links.
The "b" version was released later and uses a 9-circuit plug for increased transfer speeds. Version "a" is a little older, but "b" can be backwards compatible with the "a" interface.
Alpha and Beta maybe?
IEEE 1394b
802.3 is the IEEE standard for Ethernet devices and data managment
IEEE 802.11B is 2.4GHz, but with a maximum of only 11Mbps. IEEE 802.11G is in the 2.4GHz range, with a top speed of 54Mbps.
give the difference between serial port and parallel port
provides improved range permits increased data rates
Helo.They are 1394a &1394b. Max speed in 1394a is 400Mb/s، but max spee in 1394bis 800Mb/s.
All modern Apple Mac computers come standard with USB 2.0, Firewire (IEEE 1394a, and in some models also IEEE 1394b), and digital audio input ports.
usb2.0
IEEE 1394b can transfer at a maximum rate of 786.432 Mbit/s.
1394 Cables have 9 pins on one end and 4 pin or 6 pin connector at the other end to connect a 1394a device to a 1394b computer port to run at a slower speed.
400 mbps.. that's all.
