A port is an interface for transmitting data between a computer and other devices (such as printers, mice, keyboards or monitors), networks or other directly connected computers. For CPU, a port is used as one or more memory addresses to send or receive data. Such as dedicated hardware in an additional circuit board, places data from the device in a memory address and sends the data from the memory address to the device. Ports can be dedicated to input and output. Ports usually receive a specific type of plug for a specific purpose. For example, serial data interface, keyboard and high-speed network port all use different connectors, so it is impossible to plug the line into the wrong port.
