The interface used to connect a mobile hard drive or flash drive to a computer is usually "USB". USB is not only a serial bus standard, but also a technical specification of input and output interface, which standardizes the connection and communication between computer and external devices. The USB interface has a hot-swappable function and can be connected to a variety of peripherals, such as mouse and keyboard.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The interface used to connect a mobile hard drive or flash drive to a computer is usually "USB".

Universal Serial bus (Universal Serial Bus, abbreviation: USB) is not only a serial bus standard, but also a technical specification of input and output interface, which is widely used in personal computers, mobile devices and other information communication products, and extended to photographic equipment, digital television (set-top box), game consoles and other related fields.

USB is an external bus standard that regulates the connection and communication between computers and external devices. The USB interface has a hot-swappable function. The USB interface can connect a variety of peripherals, such as mouse and keyboard. USB was launched in 1996 by Intel and other companies at the end of 1994. It has successfully replaced serial port and parallel port, and has become a necessary interface between computers and a large number of intelligent devices.

USB devices mainly have the following advantages:

1. It can be hot swappable. That is, when users use external devices, they do not need actions such as shutting down and rebooting, but plug USB into use directly when the computer is working.

2. Easy to carry. Most USB devices are "small, light and thin", so it is convenient for users to carry a large amount of data with them. Of course, the USB hard drive is the first choice.

3. The standard is unified. What is common is the hard disk with IDE interface, the mouse and keyboard with serial port, and the printer scanner with parallel port, but with USB, all these application peripherals can be connected with personal computers with the same standard, and then there are USB hard drives, USB mice, USB printers 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, and if you connect a USB HUB with four ports, you can reconnect; four USB devices, and so on, connect all your devices to one PC at the same time without any problems.
