UAC 3.0 primarily introduces improvements for portable devices, such as reduced power usage by bursting the data and staying in low power mode more often, and power domains for different components of the device, allowing them to be shut down when not in use.

a connection-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. [2] USB4 particularly supports the tunneling of the Thunderbolt 3 protocols, namely PCI Express (PCIe, load/store interface) and DisplayPort (display interface). USB4 also adds host-to-host interfaces. [2] The host controller directs traffic flow to devices, so no USB device can transfer any data on the bus without an explicit request from the host controller. In USB2.0, the host controller polls the bus for traffic, usually in a round-robin fashion. The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port. Although there are 2.0 and 3.0 USB Type A connectors, all Type A plugs from any USB version will fit into the receptacle. However, there are certain differences between the 2.0 and 3.0 versions; for example, USB 3.0 has an additional nine pins to enable a faster data transfer rate.

A particular advantage of USB over these previous connections is that it combines data and power, largely avoiding the need for independent power supplies for external devices. That means you daisy-chain monitors to have a seamless viewing experience. Similarly, MP3 players, digital cameras and portable game consoles can be charged by a computer via a mini USB cable and share data in either direction. Though USB-C is a newer and better connector that’s about the same size, you will still see micro USB on a ton of devices, ranging from budget Android tablets to Raspberry Pis, micro controllers, digital cameras, power banks and smart home devices. Technically speaking, there is both micro USB Type-A and Type-B, but you’re only likely to see Type-B. USB Type-C Ethernet standards require electrical isolation between the networked device (computer, phone, etc.) and the network cable up to 1500VAC or 2250VDC for 60seconds. [111] USB has no such requirement as it was designed for peripherals closely associated with a host computer, and in fact it connects the peripheral and host grounds. This gives Ethernet a significant safety advantage over USB with peripherals such as cable and DSL modems connected to external wiring that can assume hazardous voltages under certain fault conditions.

USB2.0 vs FireWire". Pricenfees. Archived from the original on 16 October 2016 . Retrieved 25 August 2007. USB was designed to standardize the connection of peripherals to personal computers, both to exchange data and to supply electric power. It has largely replaced interfaces such as serial ports and parallel ports and has become commonplace on a wide range of devices. Examples of peripherals that are connected via USB include computer keyboards and mice, video cameras, printers, portable media players, mobile (portable) digital telephones, disk drives, and network adapters. USB connectors have been increasingly replacing other types as charging cables of portable devices.

The functionality of a USB device is defined by a class code sent to a USB host. This allows the host to load software modules for the device and to support new devices from different manufacturers. Thunderbolt 3 and Thunderbolt 4 use USB-C. [117] [118] [119] Thunderbolt3 has two physical 20Gbit/s bi-directional channels, aggregated to appear as a single logical 40Gbit/s bi-directional channel. Thunderbolt 3 controllers can incorporate a USB3.1 Gen2 controller to provide compatibility with USB devices. They are also capable of providing DisplayPort Alternate Mode as well as DisplayPort over USB4 Fabric, making the function of a Thunderbolt3 port a superset of that of a USB3.1 Gen2 port.
