  1. Computer Hardware

  2. Input Devices In computing, an input device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance.

  3. Keyboard Wired or wireless Keyboards for phones Ergonomic Keyboard

  4. Mouse Wired or Wireless

  5. Alternative Pointing Devices Trackballs Pointing Stick Touch pads

  6. Touch-Sensitive Pads and Touch Screens

  7. Pen Input

  8. Game Controllers

  9. Visual Input

  10. Voice Input http://www.midomi.com/ Shazam Soundhound

  11. Scanners and Readers

  12. Biometric Data

  13. Output Devices An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form.

  14. Display Devices LCD Screens CRT

  15. Display Devices – Cathode Ray Tub

  16. Display Devices – Cathode Ray Tub

  17. LCD – Liquid Crystal Display http://www.youtube.com/watch?v=jiejNAUwcQ8 RESOLUTION: 1280×1024 Pixels, 60 Hz, 8 Bit ColorNumber of bits per second displayed? Camera has Mega Pixels (Million Pixels)

  18. Speakers, Headphones, Earbuds

  19. The System Unit • The case that contains all the electronic components • Includes: • Motherboard • Processor(s) • Memory • Buses • Adapters/Expansion Slots • Drive Bays and Drives • Power Supply

  20. Motherboard Holds many of the crucial components of the system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals

  21. Processor(s) or CPU CPU: stands for Central Processing Unit. Is the hardware within a computer system which carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of a system. Multi-core – two or more CPU’s Node – Holds a Multi-core CPU

  22. Multi-Core and Parallel Processing

  23. Pipelining

  24. Threading and Hyperthreading Each CPU can handle a thread Thread does a pipeline CPU has to execute pipeline for each thread Hyper threading

  25. Cooling

  26. Video/Graphics Cards

  27. Speed and Performance Measured in Hz (number of cycles per second) Refresh Rate of TV, 60, 120, 240 Hz (GO BACK TO LCD SLIDE) Processors now at GHzThat’s 1,000,000,000 Hz (Billion)

  28. Speed and Performance

  29. Memory Hard drive RAM More on this later
