PS/2 or USB?

[iungerich1]

Looking at Mechanical keyboards here and i see allot of them have removable cords that terminate in PS/2 or usb. 

Why is this? Is there some advantage with one over the other?

 

Also i thought PS/2 was a little outdated i mean you always see them on old mouses and keyboards so why are they a seemingly common thing with the higher end of Mechanical keyboards but not mice?

In general Ps2 has better key rollover, meaning you can push more keys at the same time. Some higher end usb keyboards address this but for the cheap ones this holds true most of the time.

I'm sorry to say this is a question that has been beat to death a bazillion times and I don't really feel like typing up the long explanation of why this versus that so I will give you the short answer.

PS2 functions on action interrupts. USB functions on position polling.

 

In theory, this makes PS2 the superior format for keyboards but modern mechanical keyboards (basically all of them) are sufficiently advanced that they NO loss from PS2 (latency and rollover).

 

This same functionality makes PS2 mice FAR INFERIOR to USB mice, and as such no one should ever use a PS2 mouse anymore (and no one does).

Ah ok thanks. I probably should have looked through the forums to get my answer
