Can you explain what a task scheduler is and how it works?

Task scheduler is a system component responsible for automatically executing tasks at specific times or upon certain events.

How it works:

1. The user or system sets a schedule or conditions for task execution.
2. The scheduler stores these tasks and monitors the time or events.
3. When the time or event occurs, the scheduler launches the corresponding task.

In C#, you can use, for example, the System.Threading.Timer class or libraries like Quartz.NET for task scheduling.

Example of a simple scheduler with Timer:

using System;
using System.Threading;

class Program {
    static void Main() {
        Timer timer = new Timer(Callback, null, 0, 1000); // runs every second
        Console.ReadLine();
    }

    static void Callback(object state) {
        Console.WriteLine("Task executed: " + DateTime.Now);
    }
}

This approach allows automating repetitive operations without user intervention.
