What is the significance of atomicity in programming and how does it ensure data integrity and consistency in concurrent operations?

Atomicity in programming refers to the concept of an operation being indivisible and either fully completed or not completed at all. This ensures that concurrent operations on shared data do not interfere with each other, maintaining data integrity and consistency. By guaranteeing that operations are executed without interruption, atomicity helps prevent issues such as race conditions and data corruption in multi-threaded environments.
