  • A thread is alive if its run method is executing.
  • OS knows about each thread, and it can interrupt a thread at any time to start running a different thread.
  • It is created at the OS level and more expensive to create than coroutines.
  • It has a context-switching cost at the OS level. Saving and restoring thread state when a context switch happens eats up some of the performance gains obtained by using threads.
  • Each thread has an Event Loop object.
