What is difference between control and manage?
Some context below:
I can control/manage it.
I keep it under control/management.
It is a subject of control/management.
These phrases could seem not much native in examples but please could you look a bit over it. Is there any fundamental difference? I mean, is there more than just "This word is usually used in these kind of phrases, and that word is usually used in those kind of phrases but both phrases are synonymous either way you'll build it."
Especially I'm confused in control as check and control as do/manage. How do/manage and check be at the same time? Especially it driving me nuts in phrases like "it shall be controlled", "it shall be maintained in controlled conditions", "... is to control process output". What do they mean? Shall it be checked or shall it be done/managed?
