The C port refers to the USB Type-C interface. USB Type-C, also known as USB-C, is a universal serial bus (USB) hardware interface form. The biggest feature in appearance is that its upper and lower ends are completely consistent.
After getting acquainted with the appearance of Type-C, let's take a look at how it was produced. As early as 2015, Nokia, the former mobile phone industry giant, released a tablet computer. For the first time, this computer uses the Type-C interface as the data transmission interface, bringing the Type-C interface to the public for the first time. However, due to the decline of Nokia mobile phones, people did not pay much attention to this computer. Just when everyone thought that Type-C would withdraw from the stage of history together with this computer, only two months later, Apple released a brand new MacBook using Type-C as the data transmission interface. Soon, driven by this brand new MacBook, the Type-C interface quickly attracted the attention of the public, and was pushed to the peak of the craze for a while. Seeing this situation, Nokia could only cry silently.
We all know that compared with USB 2.0, there is actually no big difference in appearance between USB 3.0 and USB 2.0. The color of USB3.0 is generally blue, while the color of traditional USB2.0 interface is black. The biggest feature of USB3.0 is that the transmission rate exceeds USB2.0 by a lot.
Since Type-C can replace the USB interface, can it surpass USB3.0 in terms of transmission rate and transmission function?
First of all, Type-C came out with the new USB3.1. So its transfer rate is equivalent to USB3.1. But not all Type-C can have the same transmission rate as USB3.1. At present, there are still some Type-C interfaces on mobile phones whose transmission rate is only at the level of USB2.0.
Secondly, the reason why Type-C has been widely recognized by the public on laptops is because Type-C can replace almost all traditional interfaces. One interface can realize a series of functions such as charging, transmitting data, video interface, and connecting a projector.
Furthermore, compared with traditional interfaces, Type-C has a small appearance. In this era of pursuit of thinness and lightness, Type-C will be the best choice.
Finally, the power supply capability of Type-C is much stronger than that of traditional interfaces. For example, it can achieve a power output of up to 100W. It can also be used to realize two-way power supply function: it can not only supply reverse power to peripherals, but also charge itself, and the charging time will be many times higher than that of traditional interfaces.
It is precisely because Type-C has so many advantages above that it can replace the traditional data interface. So, how to use the TYPE-C interface instead of the traditional DC interface consumer?
