Q: hello world mind if you people know what's is the difference of usb to ps/2 and what is the best for gaming thank you
A: PS/2 was the old style for plugging in your mouse and keyboard into the computer, but it's still used today. It was a normal cord but the end of it was round. USB is the new way of plugging into the computer. Again, it's a normal cord but the end is flat. It is much faster and stronger. Definitely go with USB, most modern mice and keyboards made for gaming will have USB.
