# USB protocols and connectors
|
||
|
|
|
||
|
|
Different USB connectors can transfer according to different protocols. A
|
||
|
|
connector is not always tied to a specific protocol. For instance each
|
||
|
|
subsequent generation of connector is typically backwards-compatible with the
|
||
|
|
protocol of the connector that it superseded.
|
||
|
|
|
||
|
|
Some connectors are limited to slower protocols but they have the example of
|
||
|
|
being small which is a benefit for smaller devices. The USB-C connector is so
|
||
|
|
good because it is both small and capable of supporting the most advanced
|
||
|
|
protocols (USB-4 and Thunderbolt).
|
||
|
|
|
||
|
|
The main types of USB connector:
|
||
|
|
|
||
|
|
- USB-A/USB-B
|
||
|
|
- USB-A/USB-B
|
||
|
|
- Micro-USB ()
|
||
|
|
- Mini-USB
|
||
|
|
- USB-C
|
||
|
