Summary

In this chapter, we saw how processes and threads are implemented both in operating systems and in hardware. We also looked at various configurations of processor hardware and elements of operating systems involved in scheduling to see how they provide various types of task processing.

Finally, we took the multithreaded program example of the previous chapter, and ran through it again, this time considering what happens in the OS and processor while it is being executed.

In the next chapter, we will take a look at the various multithreading APIs being offered via OS and library-based implementations, along with examples comparing these APIs.
