USB is used to standardize the connection and communication between computers and external devices. It is an external bus standard widely used in the PC field. The USB interface supports the plug-and-play and hot-swap functions of the device. With the rapid development of computer hardware, the application of USB has improved the data transmission speed between external devices. The benefit to users from the increased speed is that they can use higher-performance external devices, such as USB 2.0 scanners, which can scan a 4M picture in only about 0.1 seconds, greatly improving work efficiency. Depending on the interface and data cable, USB supports devices such as scanners, printers, keyboards, mice, cameras, USB flash drives, mobile phones, MP3 players, mobile hard drives, digital cameras, external optical floppy drives, USB network cards, ADSL modems, etc. electronic product.

For data transmission, USB data cable transmission is a simpler method besides USB flash drives. This data transmission method is not only simple, but also very fast. It only takes a few seconds to scan a document that is several meters long, greatly improving work efficiency. USB data cables also support the use of many devices. Nowadays, many ports are connected through USB, such as mice, keyboards, scanners, printers, mobile phones, and some storage devices.

First of all, there are four standard wiring colors: red, white, green, and black. These four colors correspond to pins 1, 2, 3, 4, and 4 respectively. These four lines represent: 1 is power; 2 is data; 3 is data; 4 is power. Arrangement is also possible, the red line represents the power supply, usually represented by VCC. The white line and green line represent the positive and negative electrodes respectively, also represented by the letters -DATA- and -DATA. The black wire represents the ground wire, represented by the letter ground.

USB is currently a very commonly used PC interface. It can be said to be universal throughout the world. It is simple and easy to understand. There are only four wires to manage different functions. When connecting, be careful not to mix up the order, otherwise you will damage your device.
