| Client | a workstation on a network that gains access to central data files, programs, and peripheral devices through a server. |
| Inbox | a folder in a mailbox in which incoming messages are stored and displayed |
| Airbag | an inflatable plastic bag mounted under the dashboard or on the back of the front seat of a car: it cushions the driver and passengers by inflating automatically in the event of collision |
| Cylinder | a cylindrical chamber in which the pressure of a gas or liquid moves a sliding piston. |
| Catalytic Converter | an antipollution device in an automotive exhaust system that contains a catalyst for chemically converting some pollutants in the exhaust gases, as carbon monoxide, unburned hydrocarbons, and oxides of nitrogen, into harmless compounds. |
| Jet Engine | an engine, as an aircraft engine, that produces forward motion by the rearward exhaust of a jet of fluid or heated air and gases. |
| Widget | a small mechanical device, as a knob or switch, esp. one whose name is not known or cannot be recalled |
| Robot | a machine that resembles a human and does mechanical, routine tasks on command. |
| Mobility | the quality of being mobile. |
| Precision | accuracy; exactness |
| Feedback | the process of returning part of the output of a circuit, system, or device to the input, either to oppose the input (negative feedback) or to aid the input (positive feedback). |
| Manipulate | to handle, manage, or use, esp. with skill, in some process of treatment or performance |
| Electron Microscope | a microscope of extremely high power that uses beams of electrons focused by magnetic lenses instead of rays of light, the magnified image being formed on a fluorescent screen or recorded on a photographic plate: its magnification is substantially greater than that of any optical microscope. |
| Greenhouse Gasses | any of the gases whose absorption of solar radiation is responsible for the greenhouse effect, including carbon dioxide, methane, ozone, and the fluorocarbons. |
| Carbon Dioxide | a colorless, odorless, incombustible gas, CO 2 , present in the atmosphere and formed during respiration, usually obtained from coal, coke, or natural gas by combustion, from carbohydrates by fermentation, by reaction of acid with limestone or other carbonates, or naturally from springs: used extensively in industry as dry ice, or carbon dioxide snow, in carbonated beverages, fire extinguishers, etc. |
| Generator | a machine that converts one form of energy into another, esp. mechanical energy into electrical energy, as a dynamo, or electrical energy into sound, as an acoustic generator. |
| Renewable Energy Resource | any natural resource that can replenish itself naturally over time, as wood or solar energy; also called renewable energy, [ renewable energy resource ], renewable natural resource |
| Electric Current | the time rate of flow of electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit time: measured in amperes. |
| Photons | a quantum of electromagnetic radiation, usually considered as an elementary particle that is its own antiparticle and that has zero rest mass and charge and a spin of one. Symbol: γ |
| Semiconductor | a substance, as silicon or germanium, with electrical conductivity intermediate between that of an insulator and a conductor: a basic component of various kinds of electronic circuit element (semiconductor device) used in communications, control, and detection technology and in computers. |
