The connector on the end. PS/2 cables have circular ends while USB is that flat rectangle shape.
Virtually all Windows machines will have a green coloured PS/2 port for the mouse, a purple coloured PS/2 port for the keyboard and 2 USB slots. It's common for people like Dell to send a USB mouse, so the PS/2 mouse port often goes unused, however it's rare to see USB keyboards. I'm not sure if it's due to price, problems with usb keyboards on wintels, or just to keep usb slots free for other devices. They often ship a USB->PS/2 converter too, so sometimes I have the USB mouse going into the PS/2 anyway, can be handy when you're playing with obscure OSes.
