The keyboards are all the same now. Because the equipment is already very convenient.
The keyboard now has 3 ways to connect. The first is the usb interface, which is the u disk interface.
The second is that the interface has the same needle, there are several. That’s called a ps/2 interface. The reason for using this interface is that it has better effect than the usb interface. If you want to have no overrun, that is, press a button, do not release it, press a button directly, and then input both buttons into the computer. Then this requires a ps/2 interface. The plug of this interface is different from the usb interface and requires a special interface. If you know the ps/2 interface anyway, just check it out.
The third is Bluetooth. That is, a wireless connection. First of all, you need to know whether your computer or ipad can connect to a Bluetooth device.
In the case of a computer, it is to find out whether there is a Bluetooth function in the computer. If there is no Bluetooth function, there is no way to use it. But there can be a bluetooth receiver, usually in the form of a U disk, directly plugged into the usb interface, and then it becomes a device for receiving bluetooth on the computer.
The ipad is generally available. Turn on the Bluetooth function in the ipad settings, and then on this interface, it will display which Bluetooth devices have been searched. You can read Chinese and click on the connection.
