1. Understanding Computers “Getting Inside the Computer” Computer Hardware

2. Motherboards Companies –ASUS Tek, Chaintech, Intel

3. Motherboards Names –PC, AT, Baby-AT, ATX, LPX

4. Motherboard http://oc.course.com/illustrated/concepts7/index.cfm?page=selabs

5. Real Estate? Motherboard = real estate

6. Power Integrated circuits = power lines

7. Cheese Wagons Buses = mass transportation

8. Buildings Memory Chips & Adapters = buildings

9. Integrated Circuits A super thin slice of semi–conducting material packed with microscopic circuit elements such as wires, transistors, capacitors, logic gates, and resistors. Bits are represented as electrical pulses that travel over these circuits. Also called a chip, microchip and computer chip.

10. Integrated Circuit Uses Processors Memory Support circuitry ChipPackage

11. Resist, Trans & Capac Resistor: limit flow of elec. to circuit Capacitor: hold charge & work w/ transistor to hold bits Transistor: open & close circuits of computer

12. ISA Industry Standard Architecture –Mouse, Speakers –ISA only –Large

13. PCI Peripheral Component Interconnect –Sound, Video, Network –PCI Only –“Plug & Play”

14. AGP Accelerated Graphic Port –3D graphics & video –Gaming –Small

15. Refresher PC = –Ex: Desktop, Notebook, Tablet, Handheld CPU = –“Brains of computer” Input vs. Output –Example of devices… Personal Computer Central Processing Unit

16. INPUT

17. OUTPUT

18. Refresher Processing = Processor = System unit = Storage devices = Manipulation of data

19. Processor Packages DIPs (dual in-line packages ) –Has 2 sets of rows of pins that connect IC circuitry to a circuit board (“caterpillar”)

20. Processor Packages DIMMs (dual in-line memory modules) –A small circuit board containing several chips (used for memory purposes)

21. Processor Packages PGAs (Pin-grid arrays) –A square chip package with pins arranged in squares (typically used for processors)

22. Processor Packages SECs (single-edge contact cartridges) –Houses a circuit board and processor chip
