We always hope that the mobile devices carried with us become thinner and lighter, and all kinds of new mobile devices are also catering to our demand for lightness and thinness. In the process of thinning and lightening of various mobile devices, physical interfaces under various traditional standards have first become the target of being cut off due to their own size limitations.

In 2015, Apple released a 12-inch MacBook. This notebook only provides one USB Type-C interface. All external needs of users including charging can only rely on this interface; in 2016, Apple MacBook Pro is also equipped with USB Type-C interface. The 15-inch version provides 4 USB Type-C interfaces based on Thunderbolt 3 protocol, and there are no other interfaces. Although from a market perspective, the 12-inch MacBook is not a success and its life cycle is relatively short, but from a certain point of view, the MacBook is a clarion call for the popularization of the USB Type-C interface.

After 2015, the USB Type-C interface began to be applied on mobile phones, tablets, laptops and even desktop motherboards. Although the supported protocols are different, the USB Type-C interface form is indeed available everywhere.

Cutting off the traditional standard interface means that a new way is needed to solve the traditional needs of users. According to the different data volume requirements, the industry will solve these problems through wireless and high-standard new protocol interfaces. Judging from the current situation, low-power Bluetooth 5.1 solves the connection problem of low-data interactive devices such as keyboards, mice and earphones; 802.11ax (WiFi 6) solves the problem of high-speed and low-latency network connection; for those who have data transmission speed There are very demanding connections, and the industry's choice is the physical interface in the form of USB Type-C.
