Information systeminformation system, an integrated set of components for

collecting, storing, and processing data and for delivering information, knowledge, and digital products.

Business firms and other organizations rely on information systems to carry out and manage their operations, interact with their customers and suppliers, and compete in the marketplace.

For instance, corporations use information systems to reach their potential customers with targeted messages over the Web, to process financial accounts, and to manage their human resources.

Components of information systemsThe 6 components that must come together in order to produce an

information system are:

1.Hardware : These are the devices like the monitor, processor, printer and keyboard, all of which work together to accept, process, show data and information.

2.Software : The term software refers to computer programs and the manuals (if any) that support them. Computer programs are machine-readable instructions that direct the circuitry within the hardware parts of the system to function in ways that produce useful information from data.

3.Data : Data are facts that are used by programs to produce useful information. Like programs, data are generally stored in machine-readable form on disk or tape until the computer needs them.

4. Networks : Networks Are a connecting system that allows diverse computers to distribute resources.

5. Procedures: Procedures are the policies that govern the operation of a computer system. "Procedures are to people what software is to hardware" is a common analogy that is used to illustrate the role of procedures in a system.

6. People: Every system needs people if it is to be useful. Often the most over-looked element of the system are the people, probably the component that most influence the success or failure of information systems

Conclusion

The development of computer based information systems can be seen as a process in which information processing knowledge is transferred (actually embodied) into the information system being developed. This knowledge, however, needs to be updated when the systems it describes change the way in which they process information.
