⭐ Core Definition: USB-C

USB‑C, or USB Type‑C, is a 24-pin reversible connector (not a protocol) that supersedes all previous USB connectors, which were designated legacy in 2014. This connector also supersedes Mini DisplayPort and Lightning connectors. USB-C is used for a variety of purposes: exchanging data with peripheral devices, such as external drives, mobile phones, keyboards, track-pads, and mice, or between hosts, or transferring A/V-data to displays and speakers, or also powering peripheral devices and getting powered by power adapters; either through directly wired connectors, or indirectly via hubs and docking stations. This connector type can be used for other data transfer protocols besides USB, such as Thunderbolt, PCIe, DisplayPort, and HDMI. It is considered extensible, allowing the support of future protocols.

The design for the USB‑C connector was initially developed in 2012 by Intel, Apple Inc., HP Inc., Microsoft, and the USB Implementers Forum. The Type‑C Specification 1.0 was published by the USB Implementers Forum (USB-IF) on August 11, 2014. In 2016 it was adopted by the IEC as "IEC 62680-1-3".

USB-C in the context of Computer monitor

A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls.

The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. Before the mid-2000s, most monitors used a cathode-ray tube (CRT) as the image output technology. A monitor is typically connected to its host computer via DisplayPort, HDMI, USB-C, DVI, or VGA. Monitors sometimes use other proprietary connectors and signals to connect to a computer, which is less common.

USB-C in the context of Meta Quest 3

Meta Quest 3 is a standalone virtual reality (VR) headset developed by Reality Labs, a division of Meta Platforms. It was unveiled on June 1, 2023, and released on October 10, succeeding the Quest 2 as the third generation of the Meta Quest line.

As with its predecessors, the Quest 3 is a standalone device running Meta Horizon OS, a derivative of Android Open Source Project (AOSP); VR games and apps can be run natively on the headset, or streamed from a PC over USB-C or Wi-Fi. The Quest 3 features updated hardware with elements of the Quest Pro, including a thinner form factor and lenses, and additional sensors and color passthrough cameras intended for mixed reality (MR) software.

USB-C in the context of USB flash drive

A USB flash drive (UFD) (also thumb drive, memory stick, and pen drive) is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc, and usually weighs less than 30 g (1 oz). Since first offered for sale in late 2000, the storage capacities of USB drives have ranged from 8 megabytes to 1 terabyte (TB). As of 2024, 4 TB flash drives were the largest currently in production. Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and are thought to physically last between 10 and 100 years under normal circumstances (shelf storage time).

Common uses of USB flash drives are for storage, supplementary back-ups, and transferring of computer files. Compared with floppy disks or CDs, they are smaller, faster, have significantly more capacity, and are more durable due to a lack of moving parts. Additionally, they are less vulnerable to electromagnetic interference than floppy disks, and are unharmed by surface scratches (unlike CDs). However, as with any flash storage, data loss from bit leaking due to prolonged lack of electrical power and the possibility of spontaneous controller failure due to poor manufacturing could make it unsuitable for long-term archiving of data. The ability to retain data is affected by the controller's firmware, internal data redundancy, and error correction algorithms.

USB-C in the context of Mini DisplayPort

The Mini DisplayPort (MiniDP or mDP) is a miniaturized version of the DisplayPort audio-visual digital interface.

It was announced by Apple in October 2008, and by early 2013 all new Apple Macintosh computers had Mini DisplayPort, as did the LED Cinema Display. However, in 2016 Apple began phasing out the port and replacing it with the new USB-C connector. The Mini DisplayPort is also fitted to some PC motherboards, video cards, and some PC notebooks from Asus, Microsoft, MSI, Lenovo, Toshiba, HP, Dell, and other manufacturers.

USB-C in the context of Thunderbolt (interface)

Thunderbolt is the brand name of a hardware interface for the connection of external peripherals to a computer. It was developed by Intel in collaboration with Apple. It was initially marketed under the name Light Peak, and first sold as part of an end-user product on 24 February 2011.

Thunderbolt combines PCI Express (PCIe) and DisplayPort (DP) into two serial signals and provides DC power via a single cable. Up to six peripherals may be supported by a single connector through various topologies. Thunderbolt 1 and 2 use the same connector as Mini DisplayPort (MDP), whereas Thunderbolt 3, 4, and 5 use the USB-C connector and support USB devices.

USB-C in the context of MacBook (2015–2019)

The 12-inch MacBook (also called the Retina MacBook, officially marketed as the new MacBook) is a discontinued Mac laptop made by Apple, which sat between the MacBook Air and MacBook Pro in Apple's laptop lineup. It shares the same name as its predecessor that was discontinued three years prior to the release of this one.

Introduced in March 2015, it was more compact than any other notebook in the MacBook family at the time and included a Retina display, fanless design, and a Butterfly keyboard with lower key travel. It only had a single USB-C port, used for both power and data. It was revised in 2017, and discontinued in July 2019, a year after the release of the MacBook Air with Retina display.

USB-C in the context of Pixel (1st generation)

The Pixel and Pixel XL are a pair of Android smartphones designed, developed, and marketed by Google and the first smartphones to be part of the Google Pixel product line, succeeding the Nexus line of smartphones. They were officially announced on October 4, 2016 at the Made by Google event and released in the United States on October 20. On October 4, 2017, they were succeeded by the Pixel 2 and Pixel 2 XL.

The Pixels have an aluminium chassis, with a glass panel on the rear, a USB-C connector, 3.5 mm headphone jack, and a 12.3 megapixel rear-facing camera. At launch, the devices featured certain exclusive software features, including the 7.1 "Nougat" update to the Android operating system, integration with the Google Assistant intelligent personal assistant, live technical support services, and unlimited full-resolution Google Photos backup for the life of the device.
