Note: this question should be worded as What is a PS/2 port. It appears this way because WikiAnswers cannot display the / character in questions.
A PS/2 port is a computer port used for connecting keyboards and mice to computers. It was first introduced in the IBM PS/2 (Personal Series/2) line of personal computers in 1987. It is still present in some computers, but has been replaced by USB in many circumstances because it removes the possible confusion between two physically identical ports that aren't interchangeable (one for a keyboard, one for a mouse.)
A PS/2 mouse is a computer mouse that connects to a computer via a PS/2 port. A PS/2 port is a small round connector with five pinholes.
PS2 is the input format for the mouse, optical refers to the 'laser mouse' method of mouse movement. PS2 is an old format which is not supported by many newer computers, as companies favor the USB input format since it allows for faster data transfer.
green
yes.. only you have to connect it in usb port..
a motherboard mouse
No, it will cause malfunction or in some computers, will not allow the computer to turn on.
port and speed
This is called a "bus mouse" and is the precursor to PS2 technology. In the 1980s IBM compatible computers did not have a built in interface for a mouse. At the time many mouses used a serial connection (COM port). The bus mouse interface was developed by Microsoft so that the mouse would have its own dedicated interface. It was soon rendered obsolete when IBM released its next generation of PC's with the PS2 interface for keyboard and mouse.
You will probably need specific drivers for a serial mouse. Go to the manufacturer's site and look for the drivers revelant to your operating system.
On most computers, the PS/2 (Personal System/2) mouse port is located on the back, where the motherboard is located. The mouse's port is green while the keyboard's is purple.
just go to any electronic store or office supplies and buy an adapter to convert fromusb to ps2 or viceversa
PS/2 keyboard has what is called Mini-Din 6 pins and a mouse has DIN 5 pins.
