Chapter 19...Electronic Technology
A Coggle Diagram about Computers (Computers have become much smaller because of instegrated circuits. Computers today use microprocessors. and Is an electronic device that performs tasks by following instructions given on it.), Signals and Carriers (Electronic communication devices,including the telegraph send info by using signals.), Semiconductor (Is a substance that conducts an electric current better than an insulator does but not as well as a conductor does), Doping (You can change the conductivity of a semiconductor through doping.), The diodes (Its an electronic device that allows electric charge to move more easily in one direction that in the other .), Transistors (What do you you get when you sandwich three layers of semiconductors together? You get a Transistor!
A transistor is an electronic component that amplifies, or increases,current.), Analog signal (A signal whose properties can change continuosly in an given range), Digital Signals (Signals that are represented as a sequence of separates values.), Inside an Electronic Device, Using diodes to change AC to DC, Electronic Devices (Some machines can change electrical energy into other forms of energy in order to do work.), Microprocessor (A single semiconductor chip that controls and carries out a computers instructions), Hardware (The parts or pieces of equipment that makes up a computer.), Software (A set of instructions or commands that tells a computer what to do, its a computer program.), Input devices (It gives information or input, o the computer.) and Memory (Info can be stored in computers memory until it is needed)
