From LAN (cluster) computing to WAN computing

• From LAN (cluster) computing to WAN computing

• Set of machines distributed over a MAN/WAN that are used to execute parallel loosely coupled codes

• Depending on the infrastructure (soft and hard), network computing is derived in Internet computing, P2P, Grid computing, etc.
