What is the function of green mouse port?

The green mouse port, typically found on older computers, is an analog connection used to interface with a mouse. It is part of the PS/2 connector system, which includes separate ports for the keyboard (purple) and mouse (green). The green port allows for the transmission of data signals from the mouse to the computer, enabling user input for navigation and interaction with the graphical user interface. In modern computers, USB ports have largely replaced these dedicated ports.
