Document Summary

Electron"s move at a coil 1,000 feet long (in a microsecond), 30cm (in a nanosecond) and a bag of grains of pepper (in a picosecond. Pico < nano < micro < milli < kilo < mega < giga < tera < peta (10^-12, to 10^15) Arithmetic logic unit: performs basic arithmetic operations such as adding, Most modern alus have a small number of special storage units called registers. Parts are connected to one another by a collection of wires called a bus. Fetch, decode, get data if needed, execute (fetch-execute cycle) Ram is violate unlike rom (doesn"t retain its bit configuration when the power is turned off) A cd drive uses a laser to read information stored optically on a plastic disk. Resistive, capacitive and infrared are the 3 types of touch-screens. Resistive: made up of two layers of electrically conductive material (vertical/horizontal) Capacitive: made up of a laminate applied over a glass screen.
