1. Multi functional front and back insertion into Apple to make the public aware of Type-C

"The name 'Type-C' has become well-known with the release of Apple's all-new MacBook laptop, and many people exclaim, 'Wow! One interface can serve as a USB, video output, and power source with so many interfaces, it's really amazing!'"

The emergence of the Type-C interface seems to have pushed Apple to the pinnacle again. Many people believe this is Apple's feat, but little do they know that the Type-C interface had already appeared before the release of the new Macbook, and of course, the standards for Type-C were not specified by Apple. Here, I would like to silently shed a tear for the Nokia N1 tablet, as the Type-C interface equipped with N1 appeared two months earlier than the new Macbook.

So what exactly is Typc-C?

Type-C, also known as USB Type-C Interface, is a new form of USB interface that emerged with the latest USB 3.1 standard. It has been almost a year since its release (yes, it has been a year). At the end of the day, it's just a USB interface (yes). In fact, the value of Type-C for the new MacBook is not even as great as it is as a simple USB interface, because it solves the most headache inducing global problem since the emergence of USB interfaces, which is that it "no longer distinguishes directions, can be inserted in both directions", and can be inserted in both directions through USB interfaces. This is simply amazing!

The emergence of the Type-C interface can be said to have saved obsessive-compulsive disorder and Virgos, as well as eliminated headache inducing issues such as the Law of Attraction and Murphy's Law. Okay, although we know what the Type-C interface can do and what it really is, many people may still have a persistent question, which is "why is it called Type-C? Where have A and B gone?" Indeed, where have A and B gone? This is indeed a good question, and in addition, the author will delve into the development of USB standards and interfaces throughout history to make it clear to everyone.

2. Clarify all specifications of USB interfaces

Since there is Type-C, there must be Type-A and Type-B. What exactly Type-A and Type-B look like is clear at a glance in the following picture:

USB interface: Standard Type-A interface, Type-B interface, and Type-C interface from left to right

After reading the picture, everyone should suddenly realize that the Type-A interface is the most commonly used standard USB interface! Indeed, the English name for the Type-A interface is "Standard Type-A USB", which indicates that it is a standard USB interface, while other shaped USB interfaces are derivatives of it.

For the Type-B USB interface, although its appearance rate is far lower than the standard Type-A interface, I believe everyone is familiar with it, because many external USB devices such as printers, display USB HUBs, etc. use the Type-B USB interface. Generally speaking, USB interfaces on PCs are standard Type-A, while external devices often use Type-B.

Finally, there is the newly introduced Type-C interface. It has a much smaller volume than both Type-A and Type-B, and its size can even be comparable to Mini USB and Micro USB, making it the latest USB interface appearance standard. In addition, Type-C is a groundbreaking interface type that can be applied to both PC (master device) and external devices (slave device).
