What is the difference between concurrent and parallel computing?

Concurrent computing and parallel computing are two related but distinct approaches to achieving high performance in computing systems. While they have some similarities, there are also important differences between the two approaches. Concurrent computing is a form of computing where multiple tasks are executed simultaneously. In concurrent computing, the tasks are typically independent of each other and can be executed in any order. The goal of concurrent computing is to maximize the utilization of the available resources, such as processors and memory, by overlapping the execution of different tasks. Parallel computing, on the other hand, is a form of computing where a single task is divided into multiple subtasks that can be executed simultaneously on different proce....
