It's something that "appears to the rest of the program to arise instantaneously", and falls underneath categorisation of Linearizability in computing procedures. To quotation that connected short article further more:
He applied "simple", "atomic" and "nondecomposable" as casual expository notions. He understood that a relation has rows of which Each and every column has an affiliated name and benefit; characteristics are by definition "solitary-valued"; the worth is of any style.

of multitasking. The CPU scheduler can (and does) interrupt a method at any stage in its execution - even in mid perform contact. So for steps like updating shared counter variables Atomic Wallet wherever two processes could make an effort to update the variable at the same time, they have to be executed 'atomically', i.
