USB Type-B is a type of connector commonly used for connecting devices like printers, scanners, and external hard drives to computers. It has a square shape with beveled corners, which helps ensure that it can only be plugged in one way. This design makes it easy to identify and use, especially for those who may not be tech-savvy. The USB (Universal Serial Bus) standard was developed to simplify the connection of various devices. USB Type-B connectors are often found on the device side, while USB Type-A connectors are typically used on the host side, such as in computers and chargers.
