Fifth Era — Cloud computing The first era mainframe and minicomputer computing was ruled by IBM and their mainframe computers for which they supplied both the hardware and software. These computers would often take up whole rooms and require teams to run them.
As technology advanced, these computers were able to handle greater capacities and therefore reduce their cost. The second era personal computers began in as microprocessors started to compete with mainframes and minicomputers and accelerated the process of decentralizing computing power from large data centers to smaller offices.
In the late s, minicomputer technology gave way to personal computers and relatively low-cost computers were becoming mass market commodities, Information system for managers businesses to provide their employees access to computing power that ten years before would have cost tens of thousands of dollars.
This proliferation of computers created a ready market for interconnecting networks and the popularization of the Internet. The first microprocessor — a four-bit device intended for a programmable calculator — was introduced in and microprocessor-based systems were not readily available for several years.
It is arguable that the microprocessor-based system did not make significant inroads into minicomputer use untilwhen VisiCalc prompted record sales of the Apple II on which it ran.
The IBM PC introduced in was more broadly palatable to business, but its limitations gated its ability to challenge minicomputer systems until perhaps the late s to early s. Computers on a common network shared information on a server.
This lets thousands and even millions of people access data simultaneously on networks referred to as Intranets. The fourth era enterprise computing enabled by high speed networks, consolidated the original department specific software applications into integrated software platforms referred to as enterprise software.
This new platform tied all aspects of the business enterprise together offering rich information access encompassing the complete management structure.
The fifth era cloud computing is the latest and employs networking technology to deliver applications as well as data storage independent of the configuration, location, or nature of the hardware.
This, along with high speed cellphone and Wi-Fi networks, has led to new levels of mobility in which managers may access the MIS remotely with laptopstablet computers and smartphones.
Terminology[ edit ] The terms management information systems MISinformation system ISenterprise resource planning ERPcomputer scienceelectrical computer engineeringand information technology management IT are often confused.
MIS is a hierarchical subset of information systems. MIS are more organization-focused narrowing in on leveraging information technology to increase business value. Computer science is more software-focused dealing with the applications that may be used in MIS.
Management[ edit ] While management information systems can be used by any and every level of management, the decision of which systems to implement generally falls upon the chief information officers CIO and chief technology officers CTO.
These officers are generally responsible for the overall technology strategy of an organization including evaluating how new technology can help their organization.
They act as decision makers in the implementation process of new MIS. Once decisions have been made, IT directors, including MIS directors, are in charge of the technical implementation of the system.These employees hold professional and managerial positions such as accountants, bursars, registrars, human resource generalists, maintenance managers, information technology specialists and academic deans.
