For my controlled assessment in GCSE Computing one of the questions is:

How could a computer technician use the "top" command with "ps" and "kill" to investigate how a system is misbehaving?

I have to evaluate the usefulness of "top", and the question advises you do do primary research and ask IT professionals their opinions about this question, in order to use the information to evaluate in my essay.

If any one could advise me with this I would be very grateful,

(sorry about the title, I made it too long and now its cut off part of it without me realising)
