|Two of Each
Question : Can I use two keyboards on the same computer at the same
time? ie. Two USB keyboards or one connected to the PS/2 port and another
plug into the USB port.
Answer : Of course two keyboards can be connected to a PC at the same
time. You can even connect multiple keyboards and mice. But it is
pointless doing so as no two same keys are allowed to be pressed at the same time.
There won't be much desk space too with two keyboards plugged in.
