Ps & top different output

CPU usage: PS versus TOP - Different output
CPU usage: PS versus TOP - Different output


When monitoring a Linux environment with PS command, reported CPU & memory value for a certain process differs, sometimes greatly, from the value seen in TOP.

I understood this is not a bug, they report different data.
I can't understand the nature of this difference.

My Question: Can someone explain it in simple manner, or alternativly provide a link to such documentation.
