For consumers, that a small USB connector that looks fragile and had to be ready for him, especially in the smart phone's USB connector, if broken may not charge, so USB Type C design, with particular emphasis on in the "strong Naicao" afford at least 10,000 times plug, plug one day is equal to an average of five times, it can also be used for about five and a half years, which has more than the period of the regime change smartphone!
Pick up to buy a new smartphone known a charger can be generic, no longer ready for a variety of chargers, I can not help but thank God. Using mobile, for me this "old man" type of users, there is a new App, is better to use "simple" to important. Over the years, a variety of odd type Guaizhuang universal charging connector can not really annoying, but neither economical nor environmentally friendly.
Most users do not understand the principles of the product, but the product is good or bad, not durable resistance, be convenient, and it is not cheap, are all experts, we can have a lot of requirements.
Universal Serial Bus (Universal Serial Bus, abbreviated as USB) port is a serial bus standard to connect a computer system with an external device. It is the interface specification An input output, are widely used in personal computers and mobile devices and other communications products, and extension to other relevant areas of photographic equipment, digital television (set-top boxes), game consoles, of course, also entered the smartphone this area.
At first just ask the city, unified connector and plug and play feature support hot insertion of various devices, is really a great deal of convenience, USB is designed specifically for external devices, using multiple and extensive. In the external interface, it is now regarded as defeated IEEE 1394 and eSATA.
External interfaces directly to a user, a group that is not much to know, but it requires a lot of guys care more about good or bad, not durable resistance, be convenient, and it is not cheap. As for how it works inside the machine, and I, like most people have no interest, as long as "maintaining the status quo," the old equipment, and new products can be connected just fine. USB Type A, B of the interface (connector) really did this, regardless of how the alternate generation USB (USB 1.0, USB 2.0, USB 3.0), the user does not seem to increase the trouble to use.
Just USB Type A, B for a connector on your mobile device too, want to continue to maintain influence in the market, of course, to reduce the size, so there is a smaller Mini USB and Micro USB appears, continue to run rampant market, but also to I have this "old man" of the smart phone charger connector can be simplified into the rest of the Micro USB connector and another apple feel so excited.
If you want to use on mobile devices scaled-down version of USB3.0 (Micro B) In fact, the effect of less than ideal, the industry's argument is USB3.0 Micro B connector, not strong enough Naicao (Robustness). In addition USB3.0 Micro B also reach the future requirements of smart phones, this reason, it is necessary to enhance the USB3.0 specification, which is related to the connector interface, but also redesigned necessary. This new connector called USB Type C, which enhance the specifications, is USB3.1. USB Type C looks though larger than the Micro USB, but smaller than the USB Type A, attached to a computer or mobile device, the user can be estimated to be accepted. USB Type C, or USB3.1 selling point, is easy to use, and transmission speed.
(A) For consumers, ease of use is one of the selling points USB connector Type C, as long as it is aligned with the plug socket, whether positive or negative, can be used, not afraid wrong direction, which is the conventional USB connector can not do. The method used is not unusual, USB Type C uses to defeat the few multi-method, in the connector inside to pay more for a set of contacts, whether positive or negative, has a corresponding contact point, so we achieved this goal.
(Ii) transmission speed. After November 12, 2008 launch of USB 3.0, brings 5Gbps high-speed transmission performance, and bandwidth of USB 3.1 specification, much more 10Gbps. Increase the transmission speed specification does not just write about it in the specification, of course, have the appropriate supporting measures. For example, the coding rate should upgrade, USB 3.0 is 8b10b coding, which is transmitted every 10bit data, only 8bit data is real, as is the rest of the 2bit check code, so the entire bandwidth will be up to 20% (2/10 ) loss, and the new USB 3.1 is the use of 128b130b coding, 130b data, just as a check code using 4bit, transmission loss rate dropped 3%.
For consumers, USB3.1 transfer speeds than it is now on the market to use the most USB2.0 definitely feel a lot faster, but have not reached the ads claimed 10Gbps, it "knows" the good performance, and must have good surroundings with, if there is no good transmission lines, connectors and good means good, it is not up to advertising claims 10Gbps speeds. So consumers have to be psychologically prepared for a penny stock, it is necessary to spend more money in exchange for top performance.
Transmission speed, but also to USB3.1 on audio and video applications, Yan Shen it can influence. USB cable may also be replaced by other convenience, in addition to the USB interface itself is quite extensive, but also eliminates the need for a power cord to provide power directly to the USB.
The new USB AV 3.1 provides 10Gbps bandwidth of up to 4096 x 2304 @ 30FPS of 4K display screen, while USB AV also supports HDCP video encryption technology, and with a larger power supply, larger size displays also can be expected to USB AV 3.1 to display 4k resolution. In addition, existing devices and can monitor via USB AV adapter, a USB cable to transfer audio and video.
USB 3.1's hype? This is usually not a problem of concern to the consumer, but the future when USB3.1 gaining popularity, 3C store clerk to show off his expertise to you when we can not bewildered.
USB 3.1 is one of the opponent, is dominated by Intel's Thunderbolt interface, high bandwidth than USB 3.0, and supports daisy-chain (Daisy-chain) tandem applications, Thunderbolt 1.0 transmission bandwidth, there 10Gbps, Thunderbolt 2.0 transfer rate even reached 20Gbps, I believe most readers should simply not read the Thunderbolt, Thunderbolt devices currently more common, in addition to Apple computers, only a few high-end motherboard, monitor, and external storage devices have employed compared to USB, in fact, visibility low.
USB 3.1 bis rival, is already in place on the audio and video applications HDMI, HDMI 1.4 supports 4K resolution, USB AV 3.1 also shows 4K resolution, the future must have the opportunity to USB 3.1 and HDMI eating market.
In conclusion, USB 3.1 is the next generation mobile phone tablet computer common interfaces, in addition to faster speeds, the transmission rate soared over the 10Gbps, with USB 3.1 Type-C connector, so that a powerful external USB 3.1 interface and have the opportunity to dominate the future of mobile , tablet, computer transmission interface, let me this "old man" can be more convenient to do the transmission of digital data, as well as enjoy a variety of audio and video applications.
