minus-squarecheet@infosec.publinkfedilinkarrow-up40·8 天前PS2 keyboards use interrupts rather than polling in USB, meaning every time a key is pressed the CPU stops what its doing to process it.
minus-squaremfed1122@discuss.tchncs.delinkfedilinkEnglisharrow-up6·8 天前Cool! I had no idea it was deeper than just a physical interface change.

minus-squareSparroHawc@lemmy.ziplinkfedilinkarrow-up7·8 天前I know you’re probably being facetious… but the PS/2 port is what’s shown in the OP image. that said the Playstation 2 had USB ports, you could just plug a regular keyboard into it

minus-squareAurelian@lemmy.mllinkfedilinkEnglisharrow-up16·8 天前Keyboard slows down the CPU because it gets priority over whatever the CPU is working on so the keyboard could cause your system to lag. Back then all we had was single core CPUs.
