Explain the concept of concurrency and how it is related to parallelism in computer architecture.

Concurrency is the concept of executing multiple tasks or processes simultaneously in a computer system, regardless of whether they are actually executed in parallel. It allows a computer system to execute multiple tasks concurrently, which can improve performance and efficiency. Concurrency is often used in situations where multiple tasks need to be performed simultaneously, such as in web servers, database management systems, and operating systems. Parallelism, on the other hand, refers to the concept of executing multiple tasks or processes simultaneously in a computer system using multiple processors or cores. It involves dividing a task into smaller sub-tasks that can be executed in parallel, which....
