## Key points

- ‘A’ identifies the rectangular Type-A connector.
- USB-A performance varies by port and cable.
- USB-C is growing, but USB-A remains useful.

## Summary

The ‘A’ in USB-A is simply the designation for Type-A, the familiar rectangular connector; it has no special hidden meaning. The label identifies the physical connector, while the USB standard and port specifications determine what it can do.

USB-A ports can support data rates from USB 2.0’s maximum of 480 Mbps to 5 or 10 Gbps, and the connector alone does not reveal charging or data capabilities. Port symbols, specifications and device manuals can help identify performance, while colour is not a reliable universal guide. USB-C is becoming more common because it is smaller, reversible and supports newer standards, but existing USB-A devices remain useful with compatible ports or adapters.
