What is USB B?

USB B connectors are commonly found on larger devices, like printers and scanners. They are square with a beveled top. This design helps ensure they connect securely to these types of equipment.

Key Differences in Design

When comparing USB A and USB B, the design is the most noticeable difference.

1. Shape: USB A is rectangular, while USB B is more square.
2. Orientation: USB A can only be plugged in one way, whereas USB B connects through a more flexible orientation.

Different Functions

Knowing the differences in function is essential. USB A mainly connects devices like flash drives to computers. USB B, on the other hand, provides a connection for devices that need to receive data, such as printers.
