Įach specification subversion supports different maximum signaling rates from 1.5 Mbit/s in USB 1.0 to 80 Gbit/s in USB4. USB4 particularly supports the tunneling of the Thunderbolt 3 protocols, namely PCI Express (PCIe, load/store interface) and DisplayPort.
Since USB4 the specification enhances the data transfer and power supply functionality withĬonnection-oriented, tunneling architecture designed to combine multiple protocols onto a single physical interface, so that the total speed and performance of the USB4 Fabric can be dynamically shared. Īs of 2023, USB consists of four generations of specifications: USB 1.‘‘x’’, USB 2.0, USB 3.‘‘x’’, and USB4. It has become commonplace on a wide range of devices, such as keyboards, mice, cameras, printers, scanners, flash drives, smartphones, game consoles, and power banks. USB was designed to standardize the connection of peripherals to computers, replacing various interfaces such as serial ports, parallel ports, game ports, and ADB ports. keyboards and mobile devices, and intermediate hubs. Universal Serial Bus ( USB) is an industry standard that specifies the physical interfaces and protocols for connecting, data transferring and powering of hosts, such as personal computers, peripherals, e.g.
Serial port, parallel port, game port, Apple Desktop Bus, PS/2 port, and FireWire (IEEE 1394)
