Document Summary

Stand alone mainframe: house in secure area; only mis had access. Mainframe and dumb terminals: placed dumb terminals in user departments. Stand-alone personal computers: users brought personal computers to workplace. Local area networks (client/server computing): firms connected personal computers into. Enterprise computing: used network standards to integrate different kinds of networks throughout firm. Cloud computing and mobile computing: provides access to shared pool of computing resources over a network. Cloud computing: a type of computing that delivers convenient, on-demand, pay-as-you-go access for multiple customers to a shared pool of configurable computing resources, that can be rapidly and easily accessed over the internet. On-premise computing: organization own their it infrastructure (their software, hardware, licensing ), which need to spend on maintaining, staff training and salaries. Flexibility and elasticity: scale up and scale down when needed. Grid computing combines the unused processing resources of many geographically dispersed computers in a network to form a virtual supercomputer.
