How does grid computing enhance computational power?

Grid computing enhances computational power by interconnecting multiple computers to work together. This approach allows for the distribution of processing tasks across a network of computers, forming a unified resource pool. Each computer contributes its processing capability, which can significantly increase overall computational power compared to relying on a single machine.

By leveraging multiple computers, grid computing can tackle large and complex problems that require substantial processing resources. Tasks can be divided into smaller subtasks, which are then processed simultaneously by different machines, leading to faster completion times and greater efficiency.

The other choices do not effectively represent the core concept of grid computing. Adding hardware resources in one location refers more to traditional server upgrades rather than the collaborative nature of grid computing. Outsourcing to third-party services involves relying on external providers for computational tasks, which does not expand the local computational power by interconnectivity. Increasing individual computer speeds speaks to optimizing single machines rather than a collective enhancement through multiple interconnected systems.
