USB (Universal Serial Bus) has become an integral part of our modern digital lifestyle, serving as a standard connection protocol for a wide range of devices, including computers, smartphones, gaming consoles, and more. With each subsequent generation, USB has evolved to offer faster data transfer speeds and improved functionality. USB 4, the latest iteration announced by the USB Implementers Forum (USB-IF), holds significant promise for meeting the demands of future technology. In this article, we will delve into the key features and upgrades of USB 4, and explore how it differentiates itself from its predecessors, USB 3.1 and USB 3.2.
USB 4.0 is the latest USB standard that is expected to be released in mid-2019, so what is USB 4 and what is the upgrade compared to USB 3.1, 3.2 on phone and laptop devices? Let’s find out with Thptlaihoa.edu.vn now!
What is USB 4?
USB 4 is the next generation of USB 3 that uses dual channels to achieve data transfer speeds of up to 40 GB/s and improved compatibility regardless of which cable or port the user uses.
Features of USB 4
Speed
Currently, USB 3.1 and USB 3.2 only have a bandwidth of 20Gbps , which means that the USB 4 standard with a data transfer rate of 40 GB / s will transfer more than 2 times more data than the latest USB 3 standard version. 8 times faster than the first USB 3 standard, the speed will also be doubled if the same amount of data is transferred.
Compatibility
USB4 works and is backward compatible with USB 3.2, USB 2.0 and even Thunderbolt 3 standards, so chargers, displays, and drives can be connected using cables instead of a central hub.
Data visibility and separation
The USB 3 standard introduced the ability to use a single cable to send power, data, and video signals. However, due to user settings, sometimes it can only send one or the other and cause the data transfer rate to drop significantly.
On USB4, the firmware (program embedded in a piece of hardware) of the connected device splits the data in transit into two streams on the sending device and then converts the two streams back into a single data block so that the receiving device can read it correctly.
Currently, USB 4 is only for developers, the official version has not been released. It is expected that devices can use USB 4 by mid-2020.
Above is information about the characteristics of USB 4 that Thptlaihoa.edu.vn shares with you. If you have any questions, please leave a comment below the article.
In conclusion, USB 4 is the next generation of Universal Serial Bus technology that offers significant upgrades in terms of speed, power delivery, and connectivity options compared to its predecessors, USB 3.1 and 3.2. USB 4 is designed to provide consistent performance and compatibility across various devices, making it a versatile and efficient solution for connecting peripherals and external devices. Its ability to provide data transfer speeds of up to 40 Gbps, support multiple 4K displays, and deliver up to 100W of power, all over a single cable, brings a new level of convenience and functionality. Additionally, USB 4 adopts the Thunderbolt 3 protocol, further enhancing its capabilities and expanding its connectivity options. With these advancements, USB 4 is set to revolutionize the way we connect and interact with our devices, offering faster, more powerful, and more versatile connectivity in the digital age.
