Which type of dispatching is characterized by the highest delay in task processing?

The type of dispatching with the greatest delay in task processing is deferred dispatching.

In iOS and other systems, task dispatching can be:

• Immediate — the task is launched immediately after being scheduled.
• Deferred — the task is placed in a queue and executed later when the system is free.
• Periodic or timer-based — the task is scheduled to run at specific times.

Deferred dispatching is characterized by the greatest delay, as the task may wait in the queue for an indefinite period until the conditions for its execution are met.

Example: using DispatchQueue.main.asyncAfter in GCD delays the execution of a task for a specified time, increasing the delay compared to immediate execution.
