Answer
Thread: A physical execution unit.
Task: A higher-level abstraction optimized for asynchronous operations.
Quick Answer
Thread is the raw OS-level execution unit — expensive to create and manage. Task is a higher-level abstraction representing an async operation — managed by the thread pool, much cheaper. Prefer Task and async/await for async work. Use Thread only when you need precise control over execution.
