USB
USB Implementers Forum (USB-IF) is a non-profit organization dedicated to the development and promotion of Universal Serial Bus technology. USB Implementers Forum (USB-IF), announced the publication of the USB4™ specification, a major update to deliver the next-generation USB architecture that complements and builds upon the existing USB 3.2 and USB 2.0 architectures. The USB4 architecture is based on the Thunderbolt™ protocol specification recently contributed by Intel Corporation to the USB Promoter Group. It doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols.
