How are PIDs assigned Linux?

Under Unix, process IDs are usually allocated on a sequential basis, beginning at 0 and rising to a maximum value which varies from system to system. Once this limit is reached, allocation restarts at zero and again increases. However, for this and subsequent passes any PIDs still assigned to processes are skipped.

Are PIDs assigned randomly?

Indeed, it’s not random, but from the outside it might as well be. Except for the idle and so-called “system” processes; those PIDs are always the same within a version of Windows.
