Why is the USB interface popular?
USB mouse, USB keyboard, USB camera, USB printer, USB...... It's impossible to contact the computer does not come into contact with the USB of this popular extreme interface, but not everyone understand the USB interface, and it is ignored this into the life to verify the success of USB, we have to regard it as naturally there should be something from one side.
Very few people will consider a small USB interface standard. Why did it succeed? Did USB have the highest transmission rate at the time of birth? Obviously not, but it is definitely the most giant USB interface -- Mircosoft and Intel behind the industry leader of USB favored a better (the most direct example is Intel USB controller directly to do its ICH chip, and Southbridge) using Intel and Mircosoft products in the world the user does not say 100% is at least 60% above, but the most important reason for this is the successful promotion of USB.
At the same time, launched with USB IEEE 1394 interface is not such a good treatment, although the theory of IEEE 1394 transmission rate is higher than USB (IEEE 1394 serial bus transmission rate is currently the fastest), but due to the lack of a device vendor support and no penetration of USB like that.
In the case of up to eight USB 2 back interfaces, there is only one IEEE 1394 interface
So today, we tend to see a situation where a motherboard has as many as six USB interfaces without a 1394 interface. Although 1394 of the popularity of the existence of great problems, but it is still the image of the field of transmission.
