Multithreaded operating system
Any operating system consists of a number of functions, each of which
controls some small part of the system's operation. Application software
uses these functions as building blocks to create specific, more powerful
tools for the user.
Under a single-threaded operating system no individual function is
independent. All operating system work (including any work
performed by an application) consists of a single, inseparable thread of
functions and so must be performed by the same processor.
Multithreaded operating systems, like Windows NT, use functions that
are effectively independent. This allows the operating system to break
its work into separate threads of functions. Since the threads are
effectively independent, they can be followed by different processors.
