please fill in the blanks on this screen, i can't seem to find them. this output is from the TOP command on a debian machine

Cpu(s):  0.0%us,  0.2%sy,  0.0%ni, 99.8%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

i think i figured out what most of the values in this menu option

us = user process sy = system process id = idle process

what are the rest of the values here?
