What is the difference between a thread and a fiber?

Question

What is the difference between a thread and a fiber? I\'ve heard of fibers from ruby and I\'ve read heard they\'re available in other languages, could somebody explain to me

Answer 1

Threads are scheduled by the OS (pre-emptive). A thread may be stopped or resumed at any time by the OS, but fibers more or less manage themselves (co-operative) and yield to each other. That is, the programmer controls when fibers do their processing and when that processing switches to another fiber.
