ATM: Abbreviation for automated teller machine. This is a standalone machine that communicates with your bank over the internet. Some ATM units simply withdraw cash from your personal account or from a line of credit provided by your credit card company. Some accept cash deposits and read out how much money a person has in their checking or savings account.
Compound: (often used as a synonym for chemical) A compound is a substance that is formed when two or more chemical elements are combined (combined) in certain proportions. For example, water is a compound formed by two hydrogen atoms bonded to one oxygen atom.The element symbol is H2O.
conductor: (in physics and engineering) A substance through which an electric current can flow.
diode: An electronic component that functions like a one-way valve for current.
doping: (in electronics) the intentional insertion of something into a crystal or other semiconductor material. For example, manufacturers may dope the material with electrons or holes.
electricity: A flow of charge that results from the movement of negatively charged particles, usually called electrons.
electronic:Negatively charged particles. It is usually seen orbiting the outer region of the atom. Also a conductor of electricity in solids.
electronics: A device that is powered by electricity but whose properties are controlled by a semiconductor or other circuit that controls or gates the movement of charge.
element: A component of a larger structure. The smallest unit of each of the more than 100 substances (in chemistry) is one atom. Examples include hydrogen, oxygen, carbon, lithium, and uranium.
engineer: A person who uses science and mathematics to solve problems. As a verb, “engineering” means to design a device, material, or process that solves some problem or unmet need.
insulator: Substances or devices that do not easily conduct electricity.
Rin: A highly reactive non-metallic element naturally occurring in phosphates. Its scientific symbol is P. It is an important part of many chemicals and structures found within cells, including membranes and DNA.
semiconductor: A substance that can conduct electricity. Semiconductors are important components of certain new electronic technologies, such as computer chips and light-emitting diodes.
silicon: A nonmetallic semiconductor element used to create electronic circuits. Pure silicon exists as a shiny, dark gray crystalline form and a shapeless powder.
transistor: A device that functions like an electrical signal switch.
