  6. COMPUTER EXAMPLE

  7. MORE VERSATILE COMPUTER

  8. PC MOTHERBOARD

  9. MOTHERBOARD ELEMENTS CPU – Does the thinking according to Boolean logic

  10. MOTHERBOARD ELEMENTS Memory – Short term memory that CPU can access – stores digital information as 1’s and 0’s

  11. North and South Bridges North and South Bridges – control communication between processor, memory, and all the input/output devices

  12. MOTHERBOARD ELEMENTS IDE – controls communication with disc drive

  13. MOTHERBOARD ELEMENTS BIOS – Basic Input/Output System – when you turn on computer, these are the first instructions it sees – permanent memory

  14. MOTHERBOARD ELEMENTS PCI – Peripheral Component Interconnect – Input/Output Bus – Controls the audio card, Ethernet card, card to disc drive

  15. MOTHERBOARD ELEMENTS AGP – Advanced Graphics Port – Communication with video card and graphics

  16. EXAMPLE OPERATION Click mouse on internet explorer icon – message makes way to CPU

  17. EXAMPLE OPERATION CPU runs a program called “interrupt handler” to figure out what mouse wants CPU sends message to disc drive requesting file representing Explorer

  18. EXAMPLE OPERATION Disc drive sends program to memory

  19. EXAMPLE OPERATION When done, disc drive tells CPU it is done

  20. EXAMPLE OPERATION CPU pulls in instructions and follows them

  21. EXAMPLE OPERATION CPU changes what’s on screen, looks for Ethernet card

  22. iPOD NANO

  23. OTHER PORTABLE COMPUTERS 8 GB of Flash Memory Microprocessor

  24. COMPUTER CHIPS
