This document discusses different types of terminals and computer graphics. It describes dumb terminals as having only keyboard input and monitor output with no processing capabilities. Intelligent terminals can perform limited processing by accepting user input, performing editing, and formatting output for display. Point-of-sale terminals are used for retail transactions using a bar code reader. The document also discusses different types of computer graphics for business, video, and CAD/CAM applications.

1. Chapter 5 B.M.H Input and Output

2. Learning Objectives Terminals Dumb terminals Intelligent terminals Computer Graphics Business graphics Video graphics CAD/CAM, CIM

3. Terminals A device (or combination of devices) that combines both input and output capabilities. Types Dumb terminal Intelligent terminal

4. Dumb terminal The simplest type of terminal Consists of a keyboard for input a monitor for output No processing capability Connects directly to a host computer

5. Intelligent terminal Combines A keyboard A monitor with memory and a processor performing limited processing functions Example Display a input form on the screen Accept user input through the keyboard Perform editing and error-checking functions on the data Send the entire set of data to the host computer for processing When the results are sent back, the terminal could format and display those results on the screen

6. Point-of-sale (POS) terminal A combination of input and output devices designed to capture retail sales data at the point where the transaction takes place. The most familiar one Supermarket checkout station Primary input device is the bar code reader built into the counter.

7. Computer Graphics Useful in education, science, sports, computer art, and more, specially in business Business Graphics Video Graphics CAD/CAM Ex. The lines and charts of business graphics Computer-produced animated graphics on TV commercials or movies

8. Business Graphics A powerful way to impart information Colorful graphics, maps and charts - Compare data more easily - Spot trends - make decisions more quickly. As the underlying data changes, the graphs updated instantaneously More detail : Chapter 13

9. Business Graphics

10. Video Graphics A series of computer-produced pictures As creative as an animated cartoon Ex. No live human in the advertisement, the moving objects you see on television Television network’s logo and theme Arcade game with joystick

11. Video Graphics

12. CAD/CAM Provide a bridge between design and manufacturing CAD ( C omputer- A ided Design ) (Planning what a product will be) Computer SW is used to create two- and three-dimensional designs of everything Additional SW performs various engineering test such as stress tests and performance analyses. The design data can then be passed to CAM system CAM ( C omputer- A ided Manufacturing ) (Actually making the planned product) Use computer to control production equipment

13. CAD/CAM

14. CIM C omputer- I ntegrated M anufacturing Integrates CAD/CAM and the entire manufacturing process Production planning, scheduling, materials management, production control are automated under computer control, providing a balanced, efficient production process Ex) E-CIM,SAP/R3 at SAMSUMG
