What is the function of a USB port?

The function of a USB port is primarily to allow peripheral device connections. USB, which stands for Universal Serial Bus, is a standard for connecting various types of devices to computers and other systems. It enables the transfer of both data and power between connected devices.

For example, when you connect a mouse, keyboard, printer, or external hard drive to a computer using a USB port, you are facilitating communication and data transfer between these peripherals and the computer. The USB standard has evolved over time, offering different versions with increased data transfer speeds and capabilities, making it a versatile option for connecting a wide range of devices.

By contrast, increasing device processing power pertains to the internal capabilities of a computer chip or the entire system, which is outside the role of a USB port. Providing internet connectivity typically involves network ports or wireless interfaces rather than USB. Amplifying audio signals is related to specific audio equipment and not a function performed directly by USB ports.
