'History of Management Information System Essay\r'

'A management discipline system (MIS) provides information which is needed to manage organizations efficiently and effectively. focal point information systems involve three primary election resources: people, engine room, and information or finality making. counsel information systems are distinct from different information systems in that they are apply to analyze op durationtional activities in the organization. Academic all in ally, the circumstance is commonaltyly used to refer to the chemical group of information management methods tied to the mechanization or support of human decision making, e. g. decision support systems, expert systems, and administrator information systems.\r\nKenneth and Jane Laudon identify five eras of MIS organic evolution corresponding to five phases in the phylogenesis of computation applied science: 1) mainframe and minicomputer computing, 2) individual(prenominal) computers, 3) client/server networks, 4) enterprise computing, and 5 ) overcast computing. The first (mainframe and minicomputer) era was ruled by IBM and their mainframe computers, these computers would often take up whole rooms and require teams to dismission them, IBM supplied the hardware and the software. As technology go on these computers were able to handle greater capacities and so reduce their cost.\r\nSmaller, more affordable minicomputers al minored bigger businesses to run their own computing centers in-house. The scrap (personal computer) era began in 1965 as microprocessors started to struggle with mainframes and minicomputers and accelerated the process of decentralizing computing strength from greathearted info centers to small offices. In the late 1970s minicomputer technology gave way to personal computers and relatively low cost computers were becoming mass food marketplace commodities, allowing businesses to provide their employees access to computing power that ten years before would deal cost tens of thousands of d ollars.\r\nThis proliferation of computers created a ready market for interconnecting networks and the popularization of the Internet. As the complexity of the technology increased and the costs decreased, the need to care information within an enterprise as well grew, giving rise to the third (client/server) era in which computers on a common network were able to access share information on a server. This allowed for large amounts of data to be accessed by thousands and blush millions of people simultaneously.\r\nThe fourth (enterprise) era enabled by high drive networks, tied all aspects of the business enterprise together offer rich information access embrace the complete management structure. The fifth and current (cloud computing) era of information systems employs networking technology to throw overboard applications as well as data storage independent of the configuration, location or nature of the hardware. This, along with high speed cellphone and wifi networks, led to tonic levels of mobility in which managers access the MIS remotely with laptops, oral contraceptive pill pcs, and smartphones.\r\n'
