Networked computing has evolved from networks connecting computers and distributed computing through thin-client network computing in the 1980s and 1990s to Internet computing today. Centralized computing--which started with mainframes at the outset of the computing evolution, evolved to PCs, and lasted up to the 1980s--focused mainly on automating existing processes. This approach gave way as applications and systems evolved to the client-server model and the distributed computing model. The client-server model allowed for the creation of server applications responsible for the storage, analysis, and sorting of large amounts of data on central data servers, with connected workstations responsible only for front-end client applications capable of running queries, producing reports, and adding new records. Distributed computing meant that dedicated file servers also could be used throughout an internal Local-Area Network (LAN), each supporting a single application, such as e-mail, facsimile, data storage, graphics storage, or documentation storage...
