Just just in case you failed to know: Considering that the CPU can only do something at a time, the OS rotates entry to the CPU to all operating processes in minimal time-slices, to provide the illusion

'atomic' indicates it cannot be damaged down. In OS/programming terms an atomic function call is a person that can not be interrupted - the complete operate has to be executed, and not swapped out with the CPU by the OS's usual context switching till it's finish.
