Summary

In this chapter, we covered a multitude of topics including the differences between concurrency and parallelism. We looked at how they both leverage the CPU in different ways, and we also branched off into the topic of computer system design and how it relates to concurrent and parallel programming.

By now you should have an appreciation for the two main types of bottlenecks afflicting most software, and also have some idea as to how to combat this. You'll also have an appreciation for some of the different styles of system architecture used, and how we can leverage these different architectures in software design.

In the next chapter, we'll expand more on the life cycle of a thread, and how it lives on your machine.
