1, What are the main same point of USB and IEEE 1394?
usb and ieee1394 are a common external interface.
usb and ieee1394 can quickly transmit large amounts of data.
usb and ieee1394 can be linked to a number of different devices.
usb and ieee1394 support hot plug.
usb and ieee1394 can no external power.
2, What are the different points of USB and IEEE 1394?
Two different speeds. USB and IEEE 1394 transfer rate compared with the rate is the be outshone feel dwarfed
. USB transfer rate is only 12 Mbps / s, can only connect a keyboard, mouse and microphone, and other low-speed equipment, and IEEE 1394 can use 400 Mbap / s, can be used to connect digital cameras, scanners and information appliances, such as the need for high-speed equipment.
Between the different structures. When connected to the USB must have at least one computer, and must HUB need to achieve interconnection, the entire network can connect up to 127 devices. IEEE1394 does not need a computer to control all the equipment, do not need to HUB, IEEE1394 bridge can connect multiple IEEE1394 network, in other words, with IEEE 1394 achieved after 63 Taiwan IEEE 1394 equipment can also use other bridges will connect the network IEEE1394 , To unlimited connections.
Between the different intelligence. IEEE 1394 networks can increase or decrease in its equipment automatically reset network. USB HUB is connected to judge the changes in equipment.
The application of two different levels. Now USB has been widely used in various aspects of almost every PC motherboards have set up a USB interface, USB2.0 will further expand the scope of USB applications. IEEE 1394 only now being used in audio, video and other multimedia.
