What is meant by parallel processing?

Parallel processing refers to the method of executing multiple processes or programs simultaneously, effectively allowing for more efficient use of resources and faster computation. This approach is widely utilized in computer systems to enhance performance, as it enables the division of tasks into smaller, manageable segments that can be processed concurrently by multiple processors or cores.

In contrast to executing programs sequentially, where tasks are completed one after another, parallel processing enables a more collaborative approach where different parts of a task can be carried out at the same time. This is particularly beneficial in environments that require intensive data processing or complex computations, making it a pivotal concept in fields such as high-performance computing, artificial intelligence, and data analysis.

By running two programs or processes simultaneously, parallel processing maximizes efficiency and improves the speed of performance, which is central to the operation of modern computing systems.
