An onboard mouse port, also known as an integrated mouse port or a built-in mouse port, refers to a hardware port on a computer motherboard specifically designed for connecting a computer mouse directly to the motherboard. It is a standard feature found in most desktop computers and some laptop models.
The onboard mouse port is typically a circular connector, commonly known as a PS/2 port, due to its historical compatibility with PS/2 technology. It enables the connection of a PS/2 mouse to the computer system without the need for additional adapters or external devices. This port allows the mouse to send data signals to the computer, which are then processed by the mouse driver software and translated into mouse movements on the screen.
This type of port is often color-coded, with purple commonly used for keyboards and green for mice, to ensure proper identification and connection. The onboard mouse port provides a reliable and efficient means of connecting and interacting with a computer mouse, allowing users to navigate and control software applications, games, and other graphical interfaces.
However, with advancements in technology, onboard mouse ports have seen a decline in popularity as newer devices often use alternative connection methods such as USB (Universal Serial Bus). USB allows for more versatile connectivity options, including hot-swapping and support for a wider range of devices. Nonetheless, onboard mouse ports have been a staple in the computer industry, especially in older systems, and continue to serve as a reliable option for connecting traditional PS/2 mice.
