DisplayPort can be used to transmit video and audio at the same time, but you can transmit either on their own if you want. The video signal path can have six to sixteen bits per color channel, and the audio path can have up to eight channels of 24-bit uncompressed audio. This interface is capable of carrying bi-directional USB signals. Universal Serial Bus Type-C Cable and Connector Specification Revision 1.0" (PDF). USB Implementers Forum . Retrieved 27 April 2023. Even so, it boasts a nice 40 Gigabits per second of speed when operating in its dual-lane mode, and offers improved support for DisplayPort and PCI Express signals. It also further improves on the power delivery features of USB 3.X. USB takes full advantage of the additional processing power that can be economically put into peripheral devices so that they can manage themselves. As such, USB devices often do not have user-adjustable interface settings.

Starting with the USB 3.2 specification, USB-IF introduced a new naming scheme. [37] To help companies with branding of the different operation modes, USB-IF recommended branding the 5, 10, and 20Gbit/s operation modes as SuperSpeed USB 5Gbps, SuperSpeed USB 10Gbps, and SuperSpeed USB 20Gbps, respectively. [38]. USB1.0, 1.1, and 2.0 use a "speak-when-spoken-to" protocol, meaning that each peripheral communicates with the host when the host specifically requests communication. USB3.0 allows for device-initiated communications towards the host. A FireWire device can communicate with any other node at any time, subject to network conditions. doubles that by making SuperSpeed+ dual-lane (dubbed USB 3.2 x 2), resulting in a nice 20 Gigabits per second.Several manufacturers offer external portable USB hard disk drives, or empty enclosures for disk drives. These offer performance comparable to internal drives, limited by the number and types of attached USB devices, and by the upper limit of the USB interface. Other competing standards for external drive connectivity include eSATA, ExpressCard, FireWire (IEEE 1394), and most recently Thunderbolt. USB 3.1 - Type-C Host to Host". superuser.com.

DisplayPort 2.0 can support 8K resolution at 60Hz with HDR10 color. [120] DisplayPort 2.0 can use up to 80 Gbit/s, which is double the amount available to USB data, because it sends all the data in one direction (to the monitor) and can thus use all eight data wires at once.

USB provides three isochronous (fixed-bandwidth) synchronization types, [76] all of which are used by audio devices: [77] The operation modes USB3.2Gen2×2 and USB4Gen2×2 – or: USB3.2Gen2×1 and USB4Gen2×1 – are not interchangeable or compatible; all participating controllers must operate with the same mode.USB ports and plugs were developed to simplify the process of connecting multiple different USB devices and peripherals to computers.

The most popular and common USB port type today is probably the USB Type-A, also known as Standard-A. USB A connections will be very familiar to most PC or laptop users as a rectangular slot of about 14mm wide by 6mm high. USB stands for Universal Serial Bus, a common standard launched in 1996. Before this, there was a much wider variety of different connectors commonly used for linking PCs and compatible hardware. Examples you might be familiar with include multiple versions of serial ports, D-Sub, and parallel ports. The USB 3.0 specification introduced an A-to-A cross-over cable without power for connecting two PCs. These are not meant for data transfer but are aimed at diagnostic uses. The USB Type D connector coincides with version 4.1 of the USB standard, with a theoretical maximum transfer rate of 1Tb/s. Devices can request up to 1.21GW of power, provided the host's power supply has sufficient capacity.

This made USB 2.0 the first USB standard viable for external storage in the form of devices like USB flash drives and USB external hard drives. USB Type-C also debuted during the USB 2.0 era but didn’t see widespread use until USB 3.0 and later. However, these also have different connectors, which look like the originals but with…an extra bit attached. Heron, Robert. "USB2.0 Versus FireWire". TechTV.
