hi there, please help me..

please tell me how do this circuit work as anti bouncing circuit?

what is the meaning of bouncing? for example if the switch is a push button, if we push the push button once, the output will indicate that we push it severe time, is it called bouncing?

while we use the capacitor there, if the switch is off, the capacitor will charging, right? and while we push the switch button, and for example we push it for 1 minute, then the capacitor will be discharging, how long is the output pulse? is it 1 minute too? or it just as long as the capacitor is discharge itself?
