Equipped now with some methods and models to manage not only local data across single or multithreaded systems, but also distributed systems, you should start to feel pretty comfortable with protecting the validity of data in concurrent and parallel processes.

We've looked at both forms of mutual exclusions for read and read/write locks, and we have started to apply these to distributed systems to prevent blocks and race conditions across multiple networked systems.

In the next chapter, we'll explore these exclusion and data consistency concepts a little deeper, building non-blocking networked applications and learn to work with timeouts and give parallelism with channels a deeper look.

We'll also dig a little deeper into the sync and OS packages, in particular looking at the sync.atomic operations.
