RS232 – It is protocol which is used for serial communication, it is interface between computer and its peripheral devices to allow serial data exchange between them. For this communication mode done by the voltage for the path used for the data exchange between the devices.

As per below image for RS232 connector male & Female pin name.

RS422 – It is protocol which is used for serial communication, which provides asynchronous communication, It has hardware flow control, software flow control and parity. It is has capability of data transmission over long distance.
