USBCUSB4

USB4, often referred to as USB C or USB4, is a high-speed interface standard developed by the USB Implementers Forum. It is built upon the USB 3.2 specification and the Thunderbolt 3 protocol. USB4 offers a significant increase in data transfer speeds, reaching up to 40 Gbps in its dual-lane configuration. This speed allows for simultaneous data transfer and display output, making it suitable for demanding applications such as external graphics cards, high-resolution monitors, and fast storage devices.

A key feature of USB4 is its dynamic bandwidth allocation. This means that data and display traffic can share the same physical connection, with the bandwidth being allocated as needed. This optimizes performance and ensures a smoother user experience. USB4 also maintains backward compatibility with USB 3.2 and USB 2.0 devices, as well as Thunderbolt 3 devices. It utilizes the reversible USB Type-C connector, ensuring easy and correct insertion. This unified connector and protocol aim to simplify the connectivity landscape for both consumers and manufacturers.
