Introduction

Concurrency is a generalized term that describes the ability of software to do more than one thing at the same time. By harnessing the power of concurrency, you can provide a more responsive user interface by offloading CPU-intensive activities from the main UI thread. On the server side, taking advantage of modern processing power through multi-processor and multi-core architectures, scalability can be achieved by processing operations in parallel.

Multithreading is a form of concurrency whereby multiple threads are used to perform operations. This is typically achieved by creating many Thread instances and coordinating operations between them. It is regarded as a legacy implementation, having largely been replaced by parallel and async programming; you may well find it used in older projects.

Parallel programming is a class of multithreading where similar operations are run independently of each other. Typically, the same operation is repeated using multiple loops...
