  1. GRAP 3175Computer Applications for DraftingUnit IVComputer Classifications

  2. Criteria for Classifying Computers • Architecture • Design of the internal circuitry • Processing Speed • MIPS / BIPS • Number of Users • Cost

  3. Classifications • Supercomputers • Mainframe computers • Minicomputers • Workstations • Microcomputers (PCs)

  4. Supercomputers • Fastest, most powerful, and most expensive computers • National security concerns • Climate controlled computer rooms • Main memory -- Gigabytes • BIPS • CRAY, NEC, etc.

  5. Supercomputers • Several thousand users • CPU time • GigaFLOPs

  6. Mainframes • Climate controlled computer rooms • MIPS • IBM • 1000+ users

  7. Minicomputers • Do not need climate control • 100+ users • DEC, PRIME, etc.

  8. Workstations • “Souped-up” PCs

  9. Personal Computers (PC) • 1 user • Do not need climate control • Wintel PCs • Versatile

  10. Why Personal Computers are Popular • Increased productivity • Problem-solving abilities • Usefulness to a variety of people for a variety of tasks • Inexpensiveness • Availability of easy-to-use software

  11. Benchmarks in the PC Industry • Intel 4004 microprocessor 1971 -- 4-bit • Altair 8800 -- 1975 -- kit /w 1k of memory • Apple II, Commodore, Atari, TRS-80 Model I -- 1977 • IBM PC -- 1981 -- 16-bit • IBM compatibles -- 1985-6 • Tandy, Epson, Compaq, Zenith, etc. • Apple Macintosh -- 1984

  12. Benchmarks in the PC Industry • Compaq Deskpro -- 1986 -- 32-bit Intel 80386 • NeXT -- 1988 -- 32-bit Motorola 68030 • Intel 80486 -- 1989 • Intel Pentium -- 1993 • Apple Power PC • Pentium II • Apple G3

  13. Benchmarks in the PC Industry • Intel Pentium III • Apple G4

  14. Microprocessors • Intel -- IBM, compatibles • Motorola -- Macintosh, NeXT, Amiga, Tectronics • Zilog -- TRS-80 Model 4 • MOS Technology -- Apple II and IIc

  15. Conventional PCs • Towers / Desktops • Laptops / Notebooks • portable vs. transportable • docking station • Pocket PC

  16. Extended PC Family • Slate Computers • Personal Digital Assistants (PDAs) • Palm • Wearable PC • Wristwatch computer

  17. Issue of Compatibility • ROM-BIOS • Methods to obtain compatibility • Emulation Software • Second microprocessor board • Networks • Industry standards
