I believe everyone is familiar with USB data cables. With the rapid development of the mobile phone industry, OTG has gradually been integrated into our daily life. But most people are unfamiliar with OTG. Most people can't tell the difference between OTG and USB.
We all know that we can use USB data cables to connect computers and mobile phones to transfer data. It can not only connect to photos and other data in the mobile phone through the computer, but is also an indispensable tool for charging mobile devices.
So what is the role of the OTG data cable? The function of the OTG data cable is that as long as you have it, your mobile device does not need to go through a PC or a laptop, and can be directly connected to a flash drive, mouse, keyboard, and other USB devices through this data cable. In other words, as long as you use this cable, you can directly query the information in the USB drive through your mobile phone, and you can even connect a mouse to play games and type quickly through the keyboard.
The emergence of OTG saves the process of various devices needing to communicate with each other through computers. This not only expands the functions of mobile phones, but also makes it more convenient for us to connect to the Internet and better adapt to the development of today's Internet era. Of course, this has a prerequisite, that is, your digital device must support the OTG function.
Another obvious difference between OTG and USB is that when the USB data cable is connected to a computer device, the external device is powered by the computer, while when the OTG data cable is connected to a device such as a USB flash drive, it is the mobile phone that supplies power to the external device.
