 Data parallelism is a form of parallel programming that focuses on performing the same operation on multiple data elements simultaneously. This is particularly useful when you have large datasets and want to perform computations or transformations on each element independently. In C#, you can use the `Parallel.For` and `Parallel.ForEach` methods to achieve data parallelism easily. These methods allow you to iterate over collections or ranges of data in parallel, distributing the workload across multiple threads.

 This unit focused on parallelism and the Task Parallel Library (TPL). It covers how to run asynchronous tasks in parallel using the `Task.WhenAll` method, data parallelism with `Parallel.For` and `Parallel.ForEach` methods, and the use of concurrent data structures like `ConcurrentBag`, `ConcurrentQueue`, and `ConcurrentDictionary`. The content also demonstrates how to perform multiple file I/O operations concurrently.
