Understanding Computers “Getting Inside the Computer” Computer Hardware
Motherboards • Companies • ASUS Tek, Chaintech, Intel
Motherboards • Names • PC, AT, Baby-AT, ATX, LPX
Motherboard http://oc.course.com/illustrated/concepts7/index.cfm?page=selabs
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.
Chip Package Integrated Circuit Uses • Processors • Memory • Support circuitry
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
Refresher Manipulation of data • Processing = • Processor = • System unit = • Storage devices =
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
