USB-C
Definition
USB-C is a 24-pin USB connector system with a rotationally symmetrical connector. It is a connector shape, not a specific protocol.
Why It Matters
USB-C is the modern, all-in-one connector. Its reversible design is convenient, and a single USB-C port can handle data transfer, video output, and power delivery, allowing for single-cable docking stations and charging for powerful laptops.
Contextual Example
A modern laptop might only have a few USB-C ports. You can use one to charge the laptop, another to connect to an external monitor, and a third for a high-speed external SSD.
Common Misunderstandings
- Not all USB-C ports are created equal. A USB-C port on a cheap device might only support slow USB 2.0 data speeds and no video output, while a port on a high-end laptop could support the much faster Thunderbolt 4 protocol.
- USB-C is the connector; protocols like USB 3.2, USB4, and Thunderbolt define its capabilities (speed, video, power).
