MORE VERSATILE COMPUTER



PC MOTHERBOARD



MOTHERBOARD ELEMENTSCPU – Does the thinking according to Boolean logic



MOTHERBOARD ELEMENTSMemory – Short term memory that CPU can access – stores digital

information as 1’s and 0’s



North and South Bridges

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



MOTHERBOARD ELEMENTS

IDE – controls communication with disc drive



MOTHERBOARD ELEMENTS

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



MOTHERBOARD ELEMENTSPCI – Peripheral Component Interconnect – Input/Output Bus – Controls the audio

card, Ethernet card, card to disc drive



MOTHERBOARD ELEMENTSAGP – Advanced Graphics Port – Communication with video card

and graphics



EXAMPLE OPERATION

Click mouse on internet explorer icon – message makes way to CPU



EXAMPLE OPERATIONCPU runs a program called “interrupt handler” to figure out what mouse wants

CPU sends message to disc drive requesting file representing Explorer



EXAMPLE OPERATION

Disc drive sends program to memory



EXAMPLE OPERATIONWhen done, disc drive tells CPU it is done



EXAMPLE OPERATION

CPU pulls in instructions and follows them



EXAMPLE OPERATION

CPU changes what’s on screen, looks for Ethernet card
