Introduction

In this part of the course, we'll explain the motivation for and the basics of asynchronous programming in C#. Treat it like a gist or summary on the subject and not an in-depth tutorial. After completing this section, you should have a fair grasp of how asynchronous programming works in C# minus the minutiae.

Concurrency can be defined as dealing with multiple things at once. You can concurrently run several processes or threads on a machine with a single CPU but you'll not be parallel when doing so. Concurrency allows us to create an illusion of parallel execution even though the single CPU machine runs one thread or process at a time.

Parallelism is when we execute multiple things at once. True parallelism can only be achieved with multiple CPUs.

So far we've delved into the threading API of C#. But ...
