Best Answer:
"An information system can be defined technically as a set of interrelated components that collect (or retrieve), process, store, and distribute information to support decision making and control in a organization. In addition to support decision marking, coordination, control, information systems may also help managers and workers analyze problems" according to Laudon and Laudon.
Types of Information Systems:
- Transaction Processing Systems (TPS) - System that performs or records daily routine transactions such as sales order entry, payroll, employee record keeping, and shipping.
- Management Information Systems (MIS) - It designates a specific category of information to middle management. It is to monitor and control the business and predict future performance.
- Decision-Support Systems (DSS) - Support nonroutine decision making for middle management. Example of a nonroutine decision: What would be the impact on production schedules if we were to double sales in the month of December?
- Executive Support Systems (ESS) - Help Senior management to address strategic issues and long-term trends, both in the firm and in the external environment. Examples: What will employment levels be in five years? What products should we be making in five years?
I guess you could look at Google and Wikipedia as an information system from a consumer's point of view. Depending on the course you are taking...the instructor is probably looking for one the types of above. Good luck
