  1. Extended Learning Module C:Evaluating ComputerHardware & Software Management Information Systemsfor the Information Age

  2. Key Concepts • Management Information Systems • Information – processed data that has meaning • People – knowledge workers; users of information • Technology (IT) – any computer-based tool that helps knowledge workers work with information • Computer Hardware • The Toys: physical devices of a computer • Computer Software • The Smarts: set of instructions (programs) executed by the computer to perform tasks Technology XLM C: Computer Hardware and Software

  3. Categories of Computers 1/4 • Personal Digital Assistant (PDAs) • Calendar, contacts, notepad, e-mail, and Web • Touch-screen; long battery-life; integ. phone • Notebook, Laptop, and Tablet Computers • Battery-powered and wireless for mobility • More expensive than equivalent desktop • Desktop and Media Center Computers • Relatively inexpensive and expandable • Connect to other entertainment devices • Self-maintenance possible Categories XLM C: Computer Hardware and Software
