Universal Serial Bus (Universal Serial Bus, abbreviation: USB) is a Serial Bus standard, is also a technical specification of input and output interface, is widely used in personal computers and mobile devices and other information and communication products, and extended to photography equipment, digital TV (set-top box), game consoles and other related fields.
First of all, according to the development history of USB interface, it is divided into USB1.0, USB2.0, USB3.0 three generations; From the perspective of type, each generation also derives several types, such as A/B/C/ Micro /mini. Three generations development is understandable, but why are there different types of A/B/C? For example, a printer usually only requires the transfer of graphic data, so its interface can dispense with other unnecessary parts and enhance the important ones, hence the USB Type-B. It's important to note that not every generation has all five.
This is the most common and familiar interface. At present, all computers are compatible with this interface, including USB disk is also used by this interface. It has now evolved to USB 3.0 Type-A.
USB Type-B connectors are used for large devices, and the most commonly used are printer devices. Because these connectors are relatively large, they are rarely seen in portable consumer devices. In addition, it can also be seen in data storage and acquisition, video transmission, and game hardware interfaces. The style of Type-B interface is more durable than that of Type-c.
The USB Type-C interface is based on the USB 3.1 standard and is twice as fast as USB 3.0, but why not call it the new generation of USB 4.0? Because the improvement was so small, the previous USB 3.0 was more than 10 times faster than USB 2.0. In addition, The USB Type-C interface of USB 3.1 standard supports a maximum power supply capacity of 100W, which can fully meet the power supply requirements of such devices as laptop, while the power supply capacity of USB 3.0 is only 4.5W.
Apple Lighting's smaller connector makes the device thinner. Its predecessor was the 30pin port, but since the iPhone 5, it has been replaced by a smaller 8pin Lighting port. It has the characteristics of fast speed, small volume and easy to plug and remove. Of course, this interface is only available on Apple devices, again proving that Apple has always been a maverick.
These are the most common types of USB ports. If you want to learn more about USB Cable. Welcome subscribe to HornmicLink news.
