What is the thread in programming?

The thread is a fundamental concept in programming. It is a way of organizing and managing code so that it can run in parallel. The thread is a way of keeping code running in the background while the main program is running. Threads are used to parallelize tasks and to share resources among multiple threads. When the main program runs, it sends instructions to the thread that is running the task. When the task is done, the thread that was running the task sends instructions to the main program that is waiting for instructions. This process continues until all tasks are done or until one of them crashes or gets interrupted. Threads are a fundamental concept in programming because they allow programs to run in parallel and to share resources. They are also useful for managing memory and CPU usage.
