  1. Demystify Computer System Configuration/Upgrade C. Edward Chow Department of Computer Science CU Colorado Springs email: chow@cs.uccs.edu http://www.cs.uccs.edu/~chow C. Edward Chow

  2. Outline of the Talk • Overview of the computer system architecture • Apply Amdal’s Law for system performance/cost trade-off • Current trend in computer architecture C. Edward Chow

  3. A container: Power Supply Sound Card CPU Memory Hard Drive Floppy Drive CD-ROM/DVD Modem Video Capture Personal Computer System Speaker Printer Display Chassis Output Devices Input Devices Keyboard/Mouse Camcorder Scanner C. Edward Chow

  4. Laptop Portable Computer Headset/Microphone Twice expensive; Less speed; Mobile! LCD Display (14.1-12.1”) PC Card Slots Modem Card Network Card Clamp-on Video Camera Select Bay: 24xCD-ROM/DVD Floppy Battery 2nd Hard Drive (2-8GB) PentiumII Mobile Processor (300-200MHz) C. Edward Chow

  5. Choices of Display Devices Display Screen Typical Resolution Diagonal Row * Column Cost Length (in pixels) Monitor 15” (13.8”) 1024 * 758 $158 17” (15.7”) 1024 * 758 $219 19” (17.7”) 1600 * 1200 $445 21” (19.7”) 1600 * 1200 $999 LCD 15” 1024 * 758 $1150 CRT Monitor (Cathode Ray Tube) LCD Monitor (use less desk space, e.g. 6.7” depth compared with 15.9” for 15” CRT) (less radiation) (very expensive) C. Edward Chow

  6. Choices of Color Printers Print Speed Resolution Pages/min (PPM) Dots/in (DPI) Color Black Horizontal Vertical Cost Inject 1.5 4 600 * 300 $148 2.5 6 1200 * 600 $168 Laser BW 6 600 * 600 $380 Color 3 12 600 * 600 $2000 4 16 1200 * 1200 $3550 Inject Printer Laser Printer (crisp sharp and will not diffuse as some of the inject printers when touched with water) C. Edward Chow

  7. Choices of Color Scanners Color Maximum Resolution Depth Document Size Dots/in (DPI) bits/pixel Accepted Horizontal Vertical Cost 30 letter 300 * 600 $77 30 8.5x13” 600 * 1200 $260 36 letter 600 * 600 $272 Multifunction System* 24 legal 300 * 300 $370 30 legal 300 * 300 $970 The top three are Flatbed Scanners. There exist hand-held/card scanners. *: There are multifunction systems for Small Office Home office (SOHO) (including fax, color printing, color copying, and color scanning functions) that can perform color scan on individual sheet. C. Edward Chow
