USB-B

A square-shaped connector often used for printers and other large devices.
Less common than USB-A but still widely used in specific applications.

USB-C

A reversible, oval-shaped connector that is becoming the new standard.
Supports faster data transfer and higher power delivery.
Used in modern smartphones, laptops, and other devices.

Micro-USB

A smaller connector used in older smartphones and portable devices.
Gradually being replaced by USB-C.
