Haha, ok PID is program ID, you can use this to kill tasks with terminal too when you learn the commands.

USER is well from where the program is running im guessing, kind of like windows, you have system and username processes, so im guessing root is system and user is user.

STAT and RSS, not a clue,

Mem% and CPU% self explanitory really, the memory and cpu amount used.

And command is the program that is running i believe,

Hmm curious i've just noticed how settled down my device is, cpu usage spot on 2%?

After being on two days it seems to have really smoothened itself nicely.

KWOT thats awesome.
