Parallel Computing (The Method): A strategy where a single, complex task is broken down into smaller sub-tasks executed simultaneously across multiple processors or cores to save time.
Cluster Computing (The Infrastructure): An architecture that connects multiple independent computers (nodes) over a network so they function together as a single, unified system.
High-Performance Computing / HPC (The Capability & Discipline): The umbrella field that leverages advanced parallel computing techniques, massive compute clusters, high-speed networks, and specialized accelerators (like GPUs) to solve extreme, data-intensive problems.
