What is Grid?

In various contexts, "Grid" can refer to different technologies. Commonly, it refers to a grid computing system, which is a distributed computing infrastructure that enables the sharing of resources across multiple administrative domains. This allows for solving complex computational problems that would be too intensive for a single machine. Another interpretation may refer to electrical grids, which are networks for delivering electricity from suppliers to consumers. It can also simply be a layout or framework (e.g., a grid of data in a spreadsheet or a geographical grid system).
