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. A multithreaded operating system uses functions that are effectively independent. This allows the operating system to break its work into separate threads of functions.

Multithreaded
Operating Systems
Any operating system consists of a number of functions, each of which
controls some small part of the PC’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.
A multithreaded operating system uses 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.
