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.
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
AGP • Accelerated Graphic Port – 3 D graphics & video – Gaming – Small
Refresher • PC = Personal Computer – Ex: Desktop, Notebook, Tablet, Handheld • CPU = Central Processing Unit – “Brains of computer” • Input vs. Output – Example of devices…
INPUT
OUTPUT
Refresher • Processing = Manipulation of data • 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
