USB, the abbreviation of English Universal Serial Bus, is an external bus standard, which is used to standardize the connection and communication between computers and external devices. It is an interface technology applied in PC field.

Introduction:

Universal Serial Bus (USB) is a new data communication method that gradually replaces other interface standards. It was jointly formulated by computer companies and communication companies such as Intel, Compaq, Digital, IBM, Microsoft, NEC and Northern Telecom in 1995, and gradually formed an industry standard.

As a high-speed serial bus, the p>USB bus can meet the application requirements of high-speed data transmission, and it also has the advantages of simple power supply (bus power supply), convenient installation and configuration (plug and play and hot plug support), simple expansion port (up to 127 peripherals can be expanded through the hub), diversified transmission modes (four transmission modes), and good compatibility (backwards compatibility after product upgrade).

since its introduction, universal serial bus (USB) has successfully replaced serial port and parallel port, and has become one of the standard expansion interfaces and necessary interfaces for a large number of computers and intelligent devices in the 21st century, and has now developed to USB version 4..

USB has the advantages of fast transmission speed, convenient use, hot plug support, flexible connection, independent power supply, etc. It can be connected with a variety of peripherals such as keyboards, mice and mass storage devices, and this interface is also widely used in smart phones. The interaction between computers and other intelligent devices and external data is mainly based on network and USB interface.
