PS/2 full key without conflict PS/2 supports real full-key no punching. What does that mean To put it simply the system can recognize as many keys as you press on the keyboard at one time. For Usb keyboards it is relatively lacking. Although some Usb keyboards also claim to have this function they are generally made of signal simu lation. PS/2 has lower latency The interface is different and the working principle of the device is naturally different. usb works by polling the device. For example: What does your computer ask your mouse bu tton for The mouse bu tton will respond by saying move left. Similar to this question and answer method. PS/2 sends interrupt requests through the system. The mouse bu tton of the PS/2 will actively interrupt the current activity of the CPU and then tell the computer what I want to do. Compared to the USB method PS/2 has lower latency and the response time will be faster in actual use. Better PS/2 compatibility The current win7 system is still loved by many players. However during the installation process of the win7 system the USB driver is not integrated which leads to the failure of the normal use of the USB mouse bu tton. The PS/2 mouse bu tton is not limited. Although some seem to be able to use a USB mouse the simu lation effect is really mediocre and a significant delay can be seen.
