Development Of USB Cable

USB is the abbreviation of English Universal Serial BUS,  which is an external bus standard for regulating the connection and communication between computers and external devices. It is an interface applied in the PC field. Technology. USB interface supports plug-and-play and hot-swap functions of devices. USB was jointly proposed by Intel, Compaq, IBM, Microsoft and other companies at the end of 1994.

However, it has only been widely used until recently. The USB version has evolved over the years and has evolved to version 3.0, becoming the standard extension interface in current computers. 

At present, the main motherboard is USB1.1 and USB2.0, and the USB versions are compatible. USB uses a 4-pin (USB 3.0 standard 8-pin) plug as a standard plug. It can be daisy-chained to connect all peripherals, and can connect up to 127 external devices without losing bandwidth. USB requires support from the host hardware, operating system, and peripherals to work. 

At present, the motherboard generally adopts a control chipset supporting USB function, and a USB interface socket is also installed on the motherboard, and in addition to the socket of the backboard, a USB pin is reserved on the motherboard, which can be connected to the front of the chassis through a connection. 

As a front USB interface for ease of use. Moreover, the USB interface can also realize two-machine interconnection through a dedicated USB connection line, and can expand more interfaces through the Hub. USB has fast transmission speed (USB1.1 is 12Mbps, USB2.0 is 480Mbps, USB3.0 is 5 Gbps), easy to use, hot swappable, flexible connection, independent power supply, etc. It can connect mouse, keyboard, printer, Scanners, cameras, flash drives, MP3 players, mobile phones, digital cameras, mobile hard drives, external optical floppy drives, USB NICs, ADSL Modem, Cable Modem, etc., almost all external devices.

The USB interface can be used to connect up to 127 peripherals such as mice, modems and keyboards. Since its introduction in 1996, USB has successfully replaced serial and parallel ports and has become one of the must-have interfaces for today's personal computers and a large number of smart devices.
