PhysicsIn Structured Query Language, an atomic function is one that will either complete or return to its original state if a power interruption or an abnormal end occurs. In some Unix -base operating systems, an atomic operation is one in which no change can take place in the time between the setting of a mask and the receiving of a signal to change the mask.In some programming languages, including Lisp , an atom is the basic unit of executable code or data.
