Usb interface:
Universal serial bus (USB) is a serial bus standard for connecting computer systems with external devices, and it is also a technical specification for input and output interfaces. Widely used in personal computers, mobile devices and other information and communication products, and extended to photographic equipment, digital television (set-top box), game consoles and other related fields. The latest generation is USB 3. 1, the transmission speed is 10Gbit/s, the three-stage voltage is 5V/ 12V/20V, and the maximum power supply is 100W. The new Type C plug-in is no longer positive or negative.
USB devices mainly have the following advantages:
1. Hot plug. That is, when users use external devices, they don't need to turn off and turn on, but plug in USB directly when the computer is working.
2. Easy to carry. Most USB devices are small and light, which is very convenient for users to carry a lot of data with them. Of course, USB hard disk is the first choice.
3. Uniform standards. Everyone is familiar with hard disk with IDE interface, mouse and keyboard with serial port, printer and scanner with parallel port. But with USB, these application peripherals can be connected to the same standard personal computer, and then there are USB hard disk, USB mouse, USB printer and so on.
4. Multiple devices can be connected. USB often has multiple interfaces on personal computers, which can connect several devices at the same time. If a USB hub with four ports is connected, you can connect it again. Four USB devices, and so on, as far as possible, all the devices in your home can be connected to a personal computer at the same time, without any problems (note: 127 devices at most).
