Answer / Devendra Giri
NSOperation in Apple iOS is a base class for objects that perform a unit of work. It allows you to run multiple tasks concurrently, manage task dependencies and handle priority levels. NSOperationQueue is a thread-safe object pool for operations. You can add an operation to the queue, and the queue will schedule it for execution when appropriate based on priorities and availability.
