  1. OUTPUT DEVICES Stephen W. Logan

  2. OUTPUT DEVICES Adaptation to New System

  3. TYPES OF OUTPUT DEVICES • Video Display Terminals (Monitors) • Printers • Plotters • CD-ROM's • Computer Output Microforms (COM) • Audio Response Units

  4. MONITORS • VGA (Video Graphics Array) • Super VGA (Super Video Graphics Array) • XGA (Extended Graphic Array)

  5. MONITORS • RESOLUTION CAPABILITIES • CGA 320 X 200 Pixels 4 Colors • EGA 640 X 350 Pixels 16 Colors • VGA 640 X 480 Pixels 16 Colors • VGA 320 X 200 Pixels 256 Colors • SUPER VGA has 800 X 600 Pixels 256 Colors • SUPER VGA 1024 X 768 Pixels 256 Colors • XGA 1024 X 768 Pixels 65536 Colors

  8. PRINTERS

  9. INK-JET COLOR PRINTERS • Produce brilliant color images • Resolution variations • 360 X 360 dpi black text printing • 720 X 720 dpi color printing • 1440 X 720 dpi photo-realistic color images • Produce business presentation charts in color • Produce overhead transparencies in color

  10. INK-JET VERSUS LASER PRINTERS • Ink-Jet Printers are lower in cost • Ink-jet cost range ($200’s up to $1,000’s) • Laser cost range ($700’s up to $5,000’s) • Laser Printers are faster than Ink-Jet • Ink-Jet Speeds range 2-6 pages per minute • Black text averages 2-4 pages per minute • color averages 54 seconds per page • Laser Speeds generally double or triple Ink-Jet Speeds

  11. INK-JET VERSUS PLOTTERS • Ink-Jet printers are faster than plotters • Plotters often produce dull patterns and colors • Ink-Jet printers have more type styles • Ink-Jet droplets are smaller • Gives text a finer resolution

  19. DIGITAL CHARTS Panaboards

  20. CD-ROM's • OPTICAL DISK • Data “Burned” on Disk with Laser Light. • Very High Density • Some CD-ROM's store a gigabyte plus on a disk

  21. CD-ROM DISK • Types of Output • Software for Installation • Legal Investigations • Court Cases • Search for wanted individuals (name, street, zip, or area code) • Search for businesses by category and proprietor names • Provide access to all the nation’s telephone directories

  22. COMPUTER OUTPUT MICROFORMS(COM) • Older technology for storing large volumes of data indefinitely • Requires a COM Viewer • Corporations Archived Decades of Information

  23. COM VIEWER

  24. COM VIEWER

  25. COM ADVANTAGES • Less Storage Space • About 2% of space required for printer paper • Faster Retrieval Time • Faster Printing Speed • 30,000 Frames/Hour (Equiv. To 30,000 LPM Printer

  26. COM ADVANTAGES • Lower Materials Cost • 1 Carton Printer Paper (3500 pages): $25 • 13 Microfiche (3510 Frames): $1.69 • Less Weight • 1 Carton Paper: 40 lbs • 13 Microfiche 2 oz. • Lower Mailing Cost

  27. SPEAKING COMPUTERS

  28. SPEAKING COMPUTERS • TELEPHONY • Applications are rule-based systems • Generate speech that replicates human speech • Some telephony software can generate speech in a variety of accents • a deep Southern draaaawl • a nasal Noo Yawk
