The Informed User – You! Homo Conexus You are the most connected generation in history. You practice continuous computing. You are surrounded by a personal, movable information network. Your personal information network is created by constant cooperation between: the digital devices you carry; the wired and wireless networks that you access as you move about; Web-based tools for finding information and communicating and collaborating with other people. You can pull information from the Web and push your ideas back to the Web. © Voon Nam Fook/iStockphoto

Computer-Based Information Systems Software Database Hardware Computer-based information systems are information systems that use computer technology to perform some or all of their intended tasks. Hardware is a device such as a processor, monitor, keyboard or printer Software is a program or collection of programs that enable hardware to process data. Database is a collection of related files or tables containing data. Network is a connecting system (wireline or wireless) that permits different computers to share resources. Procedures are the set of instructions about how to combine the above components in order to process information and generate the desired output. People are those individuals who use the hardware and software, interface with it, or uses its output.

Types of Information Systems Information Systems Inside an Organization
Types of Information Systems Information Systems Among Organizations
Types of Information Systems Breadth of Support of Information Systems Functional area information systems Enterprise resource planning systems Transaction processing systems Interorganizational information systems A functional area information system supports a particular functional area of the organization. Enterprise resource planning systems tightly integrating the functional area ISs via a common database. Transaction processing systems support the monitoring, collection, storage, and processing of data from the organization’s business transactions. Interorganizational information systems connect two or more organizations.
Types of Information Systems (continued) Support for Organizational Employees Office automation systems Business intelligence systems Expert systems Dashboards Office automation systems typically support the clerical staff, lower and middle managers, and knowledge workers, enabling them to develop documents, schedule resources, and communicate. Business intelligence systems provide computer-based support for complex, nonroutine decisions, primarily for managers and knowledge workers. Expert systems attempt to duplicate the work of human experts by applying reasoning capabilities, knowledge, and expertise within a specific domain. Dashboards provide rapid access to timely information and access to structured information in the form of reports.
1.3 How Does IT Impact Organizations? IT reduces the number of middle managers. IT changes the manager’s job. Will IT eliminate jobs? IT impacts employees at work.
Misinformation about Information Systems Career Opportunities Myth #1: There are no computing jobs. Myth #2: There will be no IT jobs when I graduate. Myth #3: All IT-related jobs are moving offshore. Myth #4: IT salaries are lower due to cheap overseas labor.

Improvements in Health Care See video of the pill cam in action See video of daVinci Surgical Robot The patient swallows the Pill Cam (camera). The camera takes an image of the digestive tract at intervals, and sends the images to a device that patients wear on their belts. The patients take their devices to their doctors who download the images and view them on a screen. May do away with endoscopy and the need for general anesthetic for the procedure.
