What is the ps port of the computer?

The PS/2 interface is an interface on a PC-compatible computer system that can be used to connect the keyboard and mouse.

PS/2 is named after the personal computer launched by IBM in 1987: PS/2 series.

The PS/2 mouse connection is usually used to replace the old serial mouse interface (DB-9 RS-232);

The PS/2 keyboard connection is used to replace the IBM PC/AT Designed for large 5-pin DIN interface.

PS/2's keyboard and mouse interfaces are very similar in electrical characteristics. The main difference is that the keyboard interface requires two-way communication.

In the early days, if the keyboard and mouse slots were swapped, most desktop motherboards would not be able to recognize the keyboard and mouse. It doesn't matter now.

Currently, the PS/2 interface has been slowly replaced by USB. Only a small number of desktop computers still provide complete PS/2 keyboard and mouse interfaces, and a small number of machines no longer have PS/2. The machine only provides a set of PS/2 keyboard and mouse that can be shared or only the keyboard can be used.

Some mice and keyboards can use a converter to convert the interface from USB to PS/2, and there are also adapter cables that can be used to branch from USB to a PS/2 interface for keyboard and mouse.

However, since the USB interface can only support up to 6 keys on the keyboard without conflict, the PS/2 keyboard interface can support all keys at the same time without conflict.

Therefore, most motherboards still retain the PS/2 keyboard communication port, or only retain a set of PS/2 ports that can be shared by the PS/2 keyboard and mouse. Motherboards that retain both the keyboard and the mouse have now a bit less.

The PS/2 interface supports hot swap (compared to the traditional AT keyboard), but it needs to be restarted first after insertion, which is different from the current hot swap.
