Here's how fibers are described by MSDN:

A fiber is a unit of execution that must be manually scheduled by the 
application. Fibers run in the context of the threads that schedule 
them. Each thread can schedule multiple fibers. In general, fibers do 
not provide advantages over a well-designed multithreaded application. 
However, using fibers can make it easier to port applications that were 
designed to schedule their own threads.
