Since the emergence of PC, the development of interfaces has been evolving. Some of them have disappeared with the advance of time. USB is undoubtedly one of the most enduring interfaces. It has been nearly 20 years since the emergence of usb1.0 in 1996, and the interface speed has also developed from usb1.0 to usb3.1.
Each version of the innovation has brought higher transmission rate. USB transmission speed has developed from 1.0 (1.5mbps), 2.0 (480mbps), 3.0 (5Gbps) to today’s maximum transmission speed of 10Gbps. At the same time of speed innovation, each generation of USB interface type is also evolving. Today, let’s talk about the development of USB interface type.
The main reason why I want to talk about USB interface with you today is, of course, the emergence of usb3.1 type-C interface, which is very popular at present. The reason why it is so popular is that at the world-famous apple new product launch, its newly released MacBook port has been changed. The whole machine has no other interface, only one usb3.1 type-C interface, That’s why people pay attention to this interface. However, many consumers don’t know much about it. They even mistakenly think that usb3.1 type-C interface is Apple’s invention. What’s more, they think that it is the same product as Apple’s lightning cable, because they look very similar, and the same feature is that they can be inserted at will regardless of positive and negative.
In order to let you have a better understanding of this interface, let’s first review the USB interfaces we have seen over the years. This is the most common one. Before the USB2.0 era, USB interfaces were divided into several types:
Before the USB2.0 era (up to 480mbps)In fact, it’s easier to remember these interfaces:-Type A: generally used for PC-Type B: generally used for the connection of 3.5-inch mobile hard disk, printer, monitor, etc
Mini USB: generally used for digital cameras, digital cameras, measuring instruments, mobile hard disks and other mobile devicesThe portable version of USB 2.0 standard micro USB port appearsIn the USB2.0 era, micro USB interface appeared, which is a portable version of USB 2.0 standard. The next generation specification of Mini USB is smaller than the Mini USB interface used by some early mobile phones.-Micro USB interface: I believe everyone is very familiar with this interface, because most Android phones use this interface at present.
USB3.0 era – new micro USB 3.0 type B interface appears (speed up to 5Gbps)In the USB3.0 era, a new type of micro USB 3.0 B interface appears-Micro USB3.0 B interface: used on USB3.0 devices such as USB3.0 mobile hard disk.
Today – the latest usb3.1 type-C interface (up to 10Gbps) appears:
Usb3.1 was born in 2013. The organization responsible for formulating USB standard is USB promoter group, which is also the designer of USB type-C interface. Usb3.1 has three kinds of interface, namely type-A (standard-a), Type-B (micro-b) and type-c
Type-A is the most widely used USB A-type interface for computer connection; Type-B is the micro B interface, which is mainly used in smart phones, tablet computers and other devices; Type-C is mainly for thinner and thinner devices (in the future, it may unify the interface of mobile phone tablet and replace micro USB interface).
Every upgrade of USB faces the same problem, that is, the recognition and cooperation of major accessory manufacturers. In the USB3.0 era, most of the motherboard interfaces produced by major motherboard manufacturers are still USB2.0 interfaces. After all, the USB2.0 solution is more stable. There are many reasons for this, but the most important factor is still the lag of manufacturers in integrating before the platform replacement and the high cost of third-party bridging chips. However, with the implementation of native USB3.0 in Ivy bridge platform launched by Intel in 2012, it directly led people into the era of USB3.0 popularization. With the introduction of USB3.0 interface in high-end motherboards. PC peripherals manufacturers are also very fast. Kingston, western data and other well-known brands have launched mobile storage products with USB3.0 interface.
Nowadays, in order to realize the development of usb3.1, we still need the full support of motherboard and other hardware. However, some retailers have begun to sell. For example, ASUS released 14 USB 3.1 motherboards, MICROSTAR, Yingtai and other manufacturers have followed up. The development of apple notebook will also greatly promote its development. However, compared with this upgrade, mobile phones and tablets may promote the development of USB 3.1 faster.

The appearance of usb3.1 type-C interface will play a very important role for mobile devices. At present, type-C in usb3.1 is most likely to become the future connection standard, providing an integrated connection scheme of data transmission, peripheral connection, display and output.
It is reported that the European Union will force all mobile devices to unify usb3.1 interface in 2017. In addition to computers, mobile phones and tablets will be popularized at full speed next year, and this technology is also supported by Intel, Google, Microsoft and apple.
The new MacBook enables people to understand the USB type-C interface and the development trend of future devices. In the coming days, usb3.1 type-C devices will continue to appear. There is no doubt that USB type-C interface will gradually become popular in the next few years, and eventually replace USB3.0 as USB3.0 replaces USB2.0. Moreover, on mobile devices such as mobile phones and tablets, it has several features that can make mobile phones charge faster, have higher data transmission speed, and support display output. It is more suitable as the output interface of mobile devices. Most importantly, it needs a universal interface to improve the connectivity between devices. Whether these features can make usb3.1 type-C a unified interface in the future, let’s see.
