PS/2 Port

This port was premeditated by IBM for their Personal System/2 computers. The PS/2 port has survived on in other computers as the customary for keyboards and rats. Most computers come with two PS/2 ports. This helps to free valuable serial ports for modems and other serial devices. This port is fundamentally a serial port but it uses unusual addresses and interrupts than serial ports, so moving the mouse to a PS/2 port frees the serial port for use. Not all rats are PS/2 compatible so even if you have a PS/2 mouse port, you might still have an outflow for a new mouse. If you don’t have a PS/2 mouse port, you’ll either have to an adapter card that endow with one or a new motherboard that comprise one. PS/2 ports use synchronous serial signals to be in touch between the keyboard and mouse to the computer. The signals are all TTL logic level voltages (0 volts for logical 0 and +5 volts for logical 1). Bi-directional communications are supported on all PS/2 ports (mostly for keyboards but may be implemented in mouse only ports), all bi-directional transmissions are controlled by the clock and data lines.
