How to distinguish between working with Thread streams and using Task in the context of multithreading?

In C#, Thread and Task serve to organize parallel work but differ in abstraction level and usage:

• Thread — a low-level object representing an OS thread. Managing threads requires manual control: creation, start, synchronization.

• Task — a higher-level abstraction representing an asynchronous operation that can run in a thread pool. Task simplifies working with async and parallelism, integrating with async/await.

Example:

// Using Thread
Thread thread = new Thread(() => Console.WriteLine("Thread thread"));
thread.Start();

// Using Task
Task task = Task.Run(() => Console.WriteLine("Task"));
task.Wait();

In summary: Thread is direct OS thread management, Task is a convenient way to work with async and parallel operations using thread pools.
