USB interface is the expansion port on the motherboard for connecting various external devices. These expansion interfaces, can be printers, external Modem, scanners, flash drives, MP3 players, DC, DV, mobile disk, mobile phones, tablet and other external devices connected to your computer. Moreover, by extending the interface also enables the interconnection between computers Data Cables Compatible with Samsung/Android Mobile Phones 666 B0899CGMFG.
Currently, the common interface to a serial interface expansion (Serial Port), Parallel Interface (Parallel Port), universal serial bus interface (USB), IEEE 1394 interface.
Universal Serial Bus (Universal Serial Bus) referred to as USB, is the computer, digital, flat panel TVs and other products side glazing applications, an interface specification. USB interface is a four-pin interface, where the middle two pins to transfer data, both sides of the two-pin power supply to peripherals.
USB is the abbreviation for Universal Serial Bus. It is not a new bus standard, but used in the PC field of interface technology. USB is the end of 1994 by Intel, Compaq, IBM, Microsoft and other companies jointly proposed. But until recently, it was widely applied. From November 11, 1994 published a USB V0.7 version later, USB version has gone through years of development, has now been developed for the 2.0 version, a standard extension to the current computer interfaces. The current board is mainly used USB1.1 and USB2.0, the USB version of the compatibility between the well. USB plug with a 4-pin plug as standard, using the daisy-chain can connect all the peripherals up to 127 can be connected to external devices, and no loss of bandwidth. USB requires the host hardware, operating systems and peripherals to support three aspects of the work. The current board is generally used to support USB function control chipsets, motherboards are also equipped with USB interface socket, and in addition to the backplane connector, the board also set aside a USB pin, you can connect the chassis front As a USB interface for easy use (note that the wiring to the motherboard manual carefully read the map and press connect, do not pick the wrong leaving equipment damage). And the USB interface can also be connected via a special USB cable to achieve double machine interconnection, and more can be expanded through the Hub interface. With a transmission speed USB (USB1.1 is 12Mbps, USB2.0 is 480Mbps), easy to use, hot-swappable, connect flexible, independent power supply, etc., can connect a mouse, keyboard, printer, scanner, camera, flash drives, MP3 players, mobile phones, digital cameras, mobile hard drive, external optical floppy, USB, LAN, ADSL Modem, Cable Modem, etc., almost all external devices.
