USB-C
USB-C, or USB Type-C, is a connector (not a protocol) that supersedes previous USB connectors and can carry audio and/or video data, e.g. to drive multiple displays, or transfer data, e.g. to store a backup to an external drive, and providing/receiving power, such as to power a laptop or a mobile phone. It is not only applied by the USB technology, but is also used by other protocols including Thunderbolt, PCIe, HDMI, DisplayPort, and others. It is extensible to support future standards. USB-C is reversible and has 24 pins. The designation "C" is to distinguish it from the many various former USB connectors it replaced, all termed either Type-A or Type-B. Whereas earlier every USB cable had a host end A and a peripheral device end B, USB-C replaces both; a USB-C cable connects either way, and for older equipment a legacy cable has a Type-C plug at one end and either a Type-A (host) or a Type-B (peripheral device) plug at the other. The designation "C" refers only to the connector's physical configuration, or form factor, not to be confused with the connector's specific capabilities, such as Thunderbolt 3, DisplayPort 2.0, or USB 3.2 Gen 2x2.
