A thread pool is a container of pre-initialized threads that are ready to execute tasks. When a task is submitted to the thread pool, one of the idle threads is assigned the task and starts executing it. Once the task is completed, the thread returns to the pool and becomes available to execute another task. Thread pools are used to improve the performance and scalability of applications that need to process a large number of tasks concurrently. By reusing threads, thread pools avoid the overhead of creating and destroying threads for each task, which can be time-consuming and resource-intensive. Additionally, thread pools can limit the number of concurrent threads to prevent resource exhaustion and improve the overall responsiveness of the application.
