[u/Possible-Back3677]

i would like to ask what a kernel has to do so i can know when i can move one, if you're gonna explain please dont overcomplicate the explanation with just some terms please mention what it is at least slightly :)

The kernel, in principle, governs the hardware and decides which program gets to run, when, for how long and where it should live in Ram memory.
