Notebook computer connectors are interfaces and connectors used to connect and transmit signals, power, and data to various external devices and accessories for notebook computers. These connectors serve as a bridge between the laptop and external devices, providing functions such as data transfer, charging, display output, etc.
The following are some common laptop connectors and their functions:
USB (Universal Serial Bus) connector: The USB connector is one of the most common and commonly used connectors. It is used to connect various external devices such as external storage devices, printers, keyboards, mice, etc. The USB connector provides fast data transfer and charging capabilities.

It supports high-definition video and audio transmission, enabling users to enjoy a high-quality audio and visual experience on an external display.
