Answer / Brijendra Patel
NSOperationQueue can manage multiple tasks (operations) at once. The 'concurrency' property of an operation queue determines how many operations it can process simultaneously. A non-concurrent queue processes operations serially, one after another, while a concurrent queue can process multiple operations concurrently if they don't depend on each other.
