A USB connector is a standardized interface used to connect electronic devices so they can transfer data and receive power. USB stands for Universal Serial Bus, and it is widely used in computers, smartphones, tablets, peripherals, and many other electronic devices.

The USB connector is the physical part that plugs into a USB port. There are several common types, including USB-A, USB-B, Mini-USB, Micro-USB, and USB-C. Each type is designed for specific devices and uses, with USB-C being the most modern and versatile, supporting faster data transfer, higher power delivery, and reversible plugging.

USB connectors allow devices to communicate with each other, such as a keyboard sending input to a computer or a phone transferring files to a laptop. They also supply electrical power, making it possible to charge devices or power accessories through the same connection.

In summary, a USB connector provides a simple and reliable way to connect devices for data exchange and power delivery using a universal standard.
