After Apple released the new MacBook, the USB Type-C, a strange word in the eyes of ordinary people, suddenly burst into flames. For most people, it may be the first time I heard about the word USB Type-C. After Apple released the new MacBook, the USB Type-C, a strange word in the eyes of ordinary people, suddenly burst into flames. For most people, it may be the first time I heard about the word USB Type-C. In fact, it is not mysterious. It is a new type of interface that can be inserted into the front and back, can transmit data, charge, and external display.
In fact, the Type-C standard is not specified by Apple, nor is Apple first introduced. The Type-C interface of the Nokia N1 tablet has appeared two months earlier than the new Macbook. However, Apple has the special function of “innovation in inheritanceâ€, which means that although something was invented by others, Apple can make it shine.
Innovative USB 3.1 standard interface USB Type-C (USB-C for short), it has a new interface size and a slightly cool name, it is very easy for the first time to hear the term's little partner think this is a brand new USB standard, but the actual Not on. Type-C is only part of the USB 3.1 standard, not a new standard. In the latest USB 3.1 standard, there are three interface styles, one is Type-A (ie Standard-A, the most common USB interface style on traditional computers), and the other is Type-B (ie Micro-B, Samsung Galaxy, etc.) The phone is equipped with an interface style), and the other is Type-C.
In fact, USB is a standard for technology. Every new version is developed based on the technical update to consider compatibility issues with previous generations. From the perspective of interface standards, Type-A styles are theoretically compatible with almost all USB-equipped computers from the birth of USB (except for the latest Macbook and Chromebook Pixel released in 2015), because Type-A is USB3.1. Each of the previous versions was determined to be the only USB interface type that was connected to the computer.
It can be said that among the three interfaces of the USB 3.1 standard, Type-A and Type-B are more concerned with the problem of backward compatibility and unification of existing interfaces. According to the titanium media, in a sense, the existence of the two is also a compromise of the new standard for the past; of course, this compromise is necessary. Only Type-C is the most brilliant start of USB 3.1. Its groundbreaking is not only reflected in the improvement of the previous technical standards, but also more concentrated in its unprecedented appearance; this style is brand new and completely future-oriented.
Apple's 12-inch Macbook has a general release, but the USB Type-C instantly became famous all over the world. The following characteristics of Type-C determine that it is destined to represent the future of the data interface:
â— More efficient data transmission capability
The first problem to be solved in the advancement of each generation of USB standards is the problem of data transmission speed and efficiency. Under the USB 3.1 standard supported by Type-C, the theoretical transmission speed of data has been increased from 480Mbps (equivalent to 60MB per second) in the USB2.0 era to 10Gbps (equivalent to 1280MB per second), and the data transmission loss rate. Also dropped from 20% of USB3.0 to 3%.
â— More rich scalability
The computer can be connected to almost all external devices via USB, but in the transmission of audio and video, USB3.0 and its previous versions can only stay at the full HD level of 1080P, and the Type under the USB3.1 standard- The C interface can transfer up to 4K display screens.
â— Stronger power supply capability
The power supply capability of the Type-C interface under the USB3.1 standard can reach up to 20V/5A, which not only satisfies the requirements of mobile phone charging, but also satisfies the charging requirements of tablet devices and computers. In addition, under this power supply capability, it can also be exempted. To go to other external devices with higher power consumption, you need to connect to the power supply.
â—Slimer shape
Compared with the large size of Type-A and the large width of Type-B, the size of Type-C is about 8.3mm and 2.5mm. It is more suitable for people's mobile phones such as notebooks, tablets and mobile phones. Requirements. The rumored next-generation iPhone may have a thickness of 4.3mm, which is more than enough for a Type-C with a thickness of 2.5mm.
â— Both front and back can be inserted
This feature is also the most popular point of Type-C, and it is the most user-friendly place compared with other interfaces; it solves the problem of "USB can never be inserted" in any device such as computer or tablet, mobile phone and so on.
Where is the future of USB Type-C? Apple Google Microsoft Intel supports
For a new technology, the biggest problem may not be how much advanced it is than the original technology, but how many manufacturers can get support in the promotion process. However, this problem obviously does not appear on the USB Type-C.
After Apple introduced the MacBook with USB Type-C interface, Google also quickly followed up with the Chromebook Pixel with USB Type-C interface.
Intel has said, "This new industry-standard thin interface has the functions of transmitting data, charging, video transmission, etc., and all devices will need it in the future, including ultra-thin mobile phones, tablets, notebooks and desktops. â€
Microsoft has repeatedly mentioned that "Windows 10 introduces USB Dual Role and Type-C support, which will open up more new wired connectivity solutions, such as mobile phones connected to USB peripherals, or laptops and USB Type- The display of the C interface is external."
The world's first USB Type-C device is Nokia's N1 tablet. In general, there are still very few devices with USB Type-C interface available on the market, only Apple's new MacBook, Google's Chromebook Pixel, Nokia N1 tablet and LeTV 1 phone, but with Google, Apple The promotion of Microsoft, Intel, Nokia and other manufacturers, it is expected that there will be more devices using USB Type-C interface to meet with you in the future.
USB Type-C: Or will become mainstream
With the maturity of USB Type-C technology, future notebooks, tablets and even smartphones will begin to popularize the USB Type-C interface.
Micro-B: USB standard for mobile devices
Most of the current Android phones use the Micro USB interface (USB Micro-B), which is still widely used in a variety of mobile portable devices.
Type-A: Standard USB interface
Type-A is one of our most common types of USB interfaces and is commonly used on computers. But it has some significant problems: there are directions.
