  3. 3. Terminals <ul><li>A device (or combination of devices) that combines both input and output capabilities. </li></ul><ul><li>Types </li></ul><ul><ul><li>Dumb terminal </li></ul></ul><ul><ul><li>Intelligent terminal </li></ul></ul>
  4. 4. Dumb terminal <ul><li>The simplest type of terminal </li></ul><ul><li>Consists of </li></ul><ul><ul><li>a keyboard for input </li></ul></ul><ul><ul><li>a monitor for output </li></ul></ul><ul><li>No processing capability </li></ul><ul><li>Connects directly to a host computer </li></ul>
  5. 5. Intelligent terminal <ul><li>Combines </li></ul><ul><ul><li>A keyboard </li></ul></ul><ul><ul><li>A monitor </li></ul></ul><ul><ul><li>with memory and a processor </li></ul></ul><ul><ul><ul><li>performing limited processing functions </li></ul></ul></ul><ul><ul><li>Example </li></ul></ul><ul><ul><ul><li>Display a input form on the screen </li></ul></ul></ul><ul><ul><ul><li>Accept user input through the keyboard </li></ul></ul></ul><ul><ul><ul><li>Perform editing and error-checking functions on the data </li></ul></ul></ul><ul><ul><ul><li>Send the entire set of data to the host computer for processing </li></ul></ul></ul><ul><ul><ul><li>When the results are sent back, the terminal could format and display those results on the screen </li></ul></ul></ul>
  6. 6. Point-of-sale (POS) terminal <ul><li>A combination of input and output devices designed to capture retail sales data </li></ul><ul><ul><li>at the point where the transaction takes place. </li></ul></ul><ul><li>The most familiar one </li></ul><ul><ul><li>Supermarket checkout station </li></ul></ul><ul><ul><ul><li>Primary input device is the bar code reader built into the counter. </li></ul></ul></ul>
  7. 7. Computer Graphics <ul><li>Useful in education, science, sports, computer art, and more, specially in business </li></ul><ul><ul><li>Business Graphics </li></ul></ul><ul><ul><li>Video Graphics </li></ul></ul><ul><ul><li>CAD/CAM </li></ul></ul><ul><li>Ex. </li></ul><ul><ul><li>The lines and charts of business graphics </li></ul></ul><ul><ul><li>Computer-produced animated graphics on TV commercials or movies </li></ul></ul>
  8. 8. Business Graphics <ul><li>A powerful way to impart information </li></ul><ul><ul><li>Colorful graphics, maps and charts </li></ul></ul><ul><ul><li>- Compare data more easily </li></ul></ul><ul><ul><li>- Spot trends </li></ul></ul><ul><ul><li>- make decisions more quickly. </li></ul></ul><ul><ul><li>As the underlying data changes, the graphs updated instantaneously </li></ul></ul><ul><ul><li>More detail : Chapter 13 </li></ul></ul>
  9. 9. Business Graphics
  10. 10. Video Graphics <ul><li>A series of computer-produced pictures </li></ul><ul><ul><li>As creative as an animated cartoon </li></ul></ul><ul><li>Ex. </li></ul><ul><ul><li>No live human in the advertisement, the moving objects you see on television </li></ul></ul><ul><ul><li>Television network’s logo and theme </li></ul></ul><ul><ul><li>Arcade game with joystick </li></ul></ul>
  11. 11. Video Graphics
  12. 12. CAD/CAM <ul><li>Provide a bridge between design and manufacturing </li></ul><ul><li>CAD ( C omputer- A ided Design ) </li></ul><ul><ul><li>(Planning what a product will be) </li></ul></ul><ul><ul><li>Computer SW is used to create two- and three-dimensional designs of everything </li></ul></ul><ul><ul><li>Additional SW performs various engineering test such as stress tests and performance analyses. </li></ul></ul><ul><ul><li>The design data can then be passed to CAM system </li></ul></ul><ul><li>CAM ( C omputer- A ided Manufacturing ) </li></ul><ul><ul><li>(Actually making the planned product) </li></ul></ul><ul><ul><li>Use computer to control production equipment </li></ul></ul>
  13. 13. CAD/CAM
  14. 14. CIM <ul><li>C omputer- I ntegrated M anufacturing </li></ul><ul><li>Integrates CAD/CAM and the entire manufacturing process </li></ul><ul><ul><li>Production planning, scheduling, materials management, production control are automated under computer control, providing a balanced, efficient production process </li></ul></ul><ul><ul><li>Ex) E-CIM,SAP/R3 at SAMSUMG </li></ul></ul>
