  6. Clusters • a computing cluster is a collectionof PCs interconnectedvia local-area, very-low-latency, high-speed networks;

  7. Grids • a computing grid istheaggregationof a verylargenumber • ofdistributedcomputingand storage resources, interconnected via • wide-area networks. There are computing grids dedicatedtointensive • computationsof data grids thatstore, processandgiveaccesstomassive • amountsof data in theorderofhundredsof gigabytes orevenseveral • terabytes;
