Deep Sleep VS Force stop!

[ThisGuy]

Basically I was curious to know what system does to apps if I put an app into Deep Sleep. 

I assume all permissions been revoked and restricted to background data use.

And there is another question How Force Stop and Deep Sleep r different to each other.

1.Deep sleep is for conserve battery, Force stop is to free memory or free cpu.
2. In deep sleep the process is restricted step by step whereas in force stop process is stopped by pressing force stop.
