Connecting Computer Mice

A typical PS/2 connector.

Most mice on the market today use a USB connector to attach to your computer. USB is a standard way to connect all kinds of peripherals to your computer, including printers, digital cameras, keyboards and mice. See How USB Ports Work for more information about this technology.

­ Some older mice, many of which are still in use today, have a PS/2 type connector. Instead of a PS/2 connector, a few other older mice use a serial type of connector to attach to a computer. See How Serial Ports Work for more information.
