Understanding Computers “Getting Inside the Computer” Computer Hardware
Motherboards Companies –ASUS Tek, Chaintech, Intel
Motherboards Names –PC, AT, Baby-AT, ATX, LPX
Motherboard
Real Estate? Motherboard = real estate
Power Integrated circuits = power lines
Cheese Wagons Buses = mass transportation
Buildings Memory Chips & Adapters = buildings
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.
Integrated Circuit Uses Processors Memory Support circuitry ChipPackage
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
ISA Industry Standard Architecture –Mouse, Speakers –ISA only –Large
PCI Peripheral Component Interconnect –Sound, Video, Network –PCI Only –“Plug & Play”
AGP Accelerated Graphic Port –3D graphics & video –Gaming –Small
Refresher PC = –Ex: Desktop, Notebook, Tablet, Handheld CPU = –“Brains of computer” Input vs. Output –Example of devices… Personal Computer Central Processing Unit
INPUT
OUTPUT
Refresher Processing = Processor = System unit = Storage devices = Manipulation of data
Processor Packages DIPs (dual in-line packages ) –Has 2 sets of rows of pins that connect IC circuitry to a circuit board (“caterpillar”)
Processor Packages DIMMs (dual in-line memory modules) –A small circuit board containing several chips (used for memory purposes)
Processor Packages PGAs (Pin-grid arrays) –A square chip package with pins arranged in squares (typically used for processors)
Processor Packages SECs (single-edge contact cartridges) –Houses a circuit board and processor chip
