USB Data Cable Development
May 23, 2018

     USB is the abbreviation for Universal Serial BUS in English, and its Chinese abbreviation is “the serial line, which is an external bus standard that regulates the connection and communication of computers and external devices. It is an interface used in the PC field. The USB interface supports plug-and-play and hot-swap capabilities of devices that were jointly proposed by Intel, Compaq, IBM, Microsoft, and others at the end of 1994.

    However, it has only been widely used until recently. The USB version has experienced many years of development, and it has now been developed into the 3.0 version, becoming the standard expansion interface in current computers. At present, USB1.1 and USB2.0 are mainly used in the motherboard, and the USB versions are compatible with each other. USB uses a 4-pin (USB 3.0 standard 8-pin) plug as the standard plug. It can daisy-chain all peripherals and connect up to 127 external devices without losing bandwidth. USB requires the support of the host hardware, operating system, and peripherals to work. Current motherboards generally use a control chipset that supports USB functions. A USB interface socket is also mounted on the mainboard. In addition to the backplane socket, a USB pin is reserved on the mainboard and can be connected to the front of the chassis through a connection cable. As a front USB interface for ease of use. Moreover, the USB interface can also realize dual-machine interconnection through a dedicated USB connection line, and can expand more interfaces through the Hub. USB has a fast transmission speed (USB1.1 is 12Mbps, USB2.0 is 480Mbps, and USB3.0 is 5Gbps). It is easy to use, supports hot-swappable, flexible connection, independent power supply, and can be connected to a mouse, keyboard, printer, etc. Scanners, cameras, flash drives, MP3 players, cell phones, digital cameras, mobile hard drives, external optical floppy drives, USB network cards, ADSL Modem, Cable Modem, etc. Almost all external devices.

   The USB interface can be used to connect up to 127 peripherals such as a mouse, modem and keyboard. 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.
