A USB port on electronic devices serves multiple functions, primarily for data transfer and charging. With USB connections, users can transfer files between devices, such as computers, smartphones, and external drives, facilitating efficient data management. Additionally, USB ports allow devices to charge by providing a power source via a standard cable. Different USB standards, like USB 2.0, 3.0, and USB-C, denote varying levels of transfer speed and power delivery capabilities. The versatility of USB ports has made them a widely adopted standard for connecting peripherals, such as keyboards and mice.
