This refers to a highly distributed computing model in which a group of computers and computing devices from various locations are interconnected to each other and each of them configured to contribute their unutilized resources to form a much bigger computing system to do some heavy processing. The location of the contributing computing devices or computers could be geographically discrete and even the type of devices/computers could be heterogeneous as well. These resources, thus, form a huge computing grid just like the electricity grids.
Basically, grid computing breaks down much complex tasks into smaller and simpler tasks based on some predefined configuration policy and then these smaller tasks are distributed to CPUs ...
