👉 Parallelization is a process of distributing data or tasks across multiple processors or cores on a computer system. It's used to speed up computation by breaking down large problems into smaller, more manageable parts that can be executed simultaneously. This allows for faster processing times and better utilization of computing resources. In the context of parallel programming, it refers to dividing a problem into smaller subproblems, then solving each subproblem independently and combining their solutions to obtain the final solution.
