There’s a big difference between types primitive and types atomic.

Atomic types are free of data breeds and can be modified and/or accessed by two different threads. An atomic data is widely used when, for example, we have 2 different actions that are performed in this data, such as reading and writing, this data type is also widely used in operating systems, where it is necessary that a data is accessed by different threads.

It is wrong to say this, but it would be something close to an asynchronous operation.

    Data race would be a way of saying "data types" - int, float, etc...
