what is the grid computing ?

Grid computing is a computational model that involves the coordination and sharing of resources across multiple computers or locations to solve complex problems. It allows organizations to combine computing power, storage, and network resources from various sources, such as servers, computers, and data centers, to perform tasks that require high computational power or storage capacity. Grid computing enables users to access and utilize resources on-demand, leading to increased efficiency, flexibility, and cost-effectiveness in handling large-scale computing tasks.
