Because threads can only be active within the scope of a single process, creating a line turndown creates a process that is inexpensive. Threads allow collaboration and exchange of data. Threads require the support of the operating system, not all machines provide threads.2, the concept of threadingThreads are sub-tasks that are independent of each other and can run independently, and each thread has its own call stack.
