  1. What are they? Computer Components

  2. Computer Components CPU Input Output Class Poll

  3. Computer Components RAM Byte ROM Class Poll

  4. Computer Components GHz Megabyte MHz Processor Speed Class poll

  5. Typical PC Hardware Hardware of Personal Computer.1. Monitor2. Motherboard3. CPU4. RAM Memory5. Expansion card6. Power supply7. CD-ROM Drive8. Hard Disk9. Keyboard10. Mouse

  6. Software • Operating Systems: MS Windows, Apple OS X • Applications: (MS Office, Final Cut Pro, Adobe CS4 • Games: World of Warcraft, The Sims

  7. Hardware Components in the computer: • Click on: start/computer/system properties/device manager Hardware

  8. AN NVIDIA RIVA 128 AGP VIDEO CARD (*) • These are expansions cards (computer components) that are designed to produce images for the computer display. Video Cards Graphics Cards

  9. Input Devices • Keyboard • Mouse • Trackball • Graphics tablet • Game Controllers • Touch screen • Webcam • Microphone

  10. Motherboard • Central Processing Unit • The “Brain” of the computer • What comes in and out?

  11. CPU • Central Processing unit • The “Brain” of the computer • Measured in MHz (Megahertz) or GHz (Gigahertz) Hertz = Cycles Per Second Mega = 1,000,000 Giga = 1,000,000,000

  12. Memory RAM Random Access Memory • Temporary • Flexible

  13. Empty RAM—2 GB Memory RAM

  14. Operating System—1 GB Empty RAM—1 GB Memory RAM

  15. Program—750 MB OS—1 GB Empty RAM—250 MB Memory RAM

  16. RAM So how is RAM measured?

  17. Based on Bit - 0 or 1, On/OFF • Byte = 8 bits • K= Kilobyte =1000 • MB = Megabyte = 1,000,000 • GB = Gigabyte = 1,000,000,000 • TB = Terabyte = 1,000,000,000,000 • PB = Petabyte = 1,000,000,000,000,000 (quadrillion) • History: According to Kevin Kelly of the New York Times, "the entire works of humankind, from the beginning of recorded history, in all languages" would amount to 50 petabytes of data. (*) MEMORY Measured in…

  18. Output Devices

  19. Output Devices • Monitor • Printer • Sound

  20. MonitorS • CRT- Cathode - Ray Tube The cathode ray tube (CRT) • vacuum tube containing an electron gun (a source of electrons) • fluorescent screen with internal or external means to accelerate and deflect the electron beam • LCD Display - Liquid Crystal Display A liquid crystal display (LCD) • thin, flat panel used for electronically displaying information

  21. Monitors • A plasma display panel (PDP) • Flat panel display common to large TV displays (32" inches or larger) • Tiny video projector takes a video signal and projects the corresponding image on a projection screen using a lens system. • Cells between two panels of glass hold a mixture of noble gases.

  22. Printers • Laser printer • Inkjet printers

  23. COMPUTER SOUND OPTIONS A PAIR OF HARMAN KARDON SOUNDSTICKS II NEXT TO AN APPLE CINEMA DISPLAY (*) • Standard or dedicated audio • Built in Speakers • External Speakers • Subwoofer • Headphones (with or without a mic) Sound

  24. Storage Devices

  25. Storage Devices • Diskette—Floppy Disk • Hard Drive • DVD • Cassette • Optical—Zip • USB Flash Drive • CD-ROM, CD-R, CD-RW • Blu-Ray Disks

  26. Networking – Connecting Computer • Network Card • Allows access to computer networks • LANS - Local area networks - etc. • WANS – Wide area Network • Modem (Dial-up) • Cable Modem • DSL (Digital Subscriber lines-data transfer over copper cable) • Wireless (Wi-Fi) • Satellite • Visualization of LAN versus WAN (*)
