TECHNOLOGY
processes and knowledge that can be used to extend human abilities as well as satisfy human needs and wants.
SYSTEM
a group of parts that work together to accomplish a goal. The basic parts of a system are input,process, and output.
INPUT
a resource that is entered into a system.
PROCESS
a series of operations that includes all of the activities that must be performed in order for the system to yield the expected result.
FEEDBACK
any information about the output of a system that is returned to the system for the purpose of determining whether or not the system is functioning as it should.
IMPACTS
the effect of a system's processes and/or output on the systems environment. this effect can be either positive, negative, or in some cases both.
TECHNOLOGY ASSESSMENT
studying the effects of a given technology to determine its impact.
TREND
a popular movement.
ENERGY
the capacity to do work or exert effort.
INFRASTRUCTURE
the basic framework of a system
TEAM
a group of people working together to accomplish a common goal.
ENGINEERING
the combination of knowledge of science, mathematics, technology, and communication to solve technology problems.
DESIGN
creating things through the process of planning.
CRITERIA
standards that a product must meet to be accepted.
CONSTRAINTS
restriction or limit placed on a product.
OPTIMIZATION
the process of creating the most effective and functional product or process while meeting all the criteria and constraints.
ENTREPRENEUR
someone who starts a business.
CRITICAL THINKING
the process of turning abstractions of thought into concrete ideas.
ANALYSIS
the act of breaking a particular subject into different parts to achieve clarity of understanding.
SYNTHESIS
the act of putting different things together to form a new product or idea.
EVALUATION
the judgement of the end result based upon given criteria.
HUMAN FACTORS ENGINEERING
the design of equipment and environments to promote human health, safety, and well-being; sometimes referred to as ergonomics.
BRAINSTORMING
an activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.
SIMULATION
the imitation, as closely as possible, of the real-life circumstances in which a solution is intended to be used.
COMMUNICATION TECHNOLOGY
the knowledge, tools, machines, skills, and other things that people make and do to send and receive information.
SENSORS
a device capable of detecting (sensing) changes in its environment; light and movement are examples.
COMMUNICATION CHANNEL
the path by which a message travels from the sender to receiver.
IDENTITY THEFT
the unlawful acquisition of some one's personal information for use without their consent.
CIRCUIT
the path by which electric current or pulses flow.
MOTHERBOARD
in a computer, the primary circuit board to which all internal componnets are connected either directly or indirectly.
CENTRAL PROCESSING UNIT(CPU)
a specialized processor that resides directly on the motherboard of a computer. It can be thought as the brain of a computer. It processes the data; also referred to as a microprocessor or a "computer within the computer."
HARD DISK
the long term storage mechanism of a computer. It holds the computer programs used for word processing, playing games, and other tasks.
PROGRAMMING LANGUAGE
a language, used to write computer programs, that can easily be translated into machine language.
ELECTROMAGNETIC WAVES
A wave created by electric and magnetic fields;it travels through the air like ripples in a pool of water.
AMPLITUDE
The height of a wave measured from the top of its peak to the bottom of its trough. It is an indicator of the strength of a wave.
FREQUENCY
the number of waves that pass through a given point in one second. It is commonly measured in a unit called hertz. 1Hz is equal to one complete wave cycle in one second.
RECEIVERS
a unit that collects waves and decodes information contained within those waves.
MODULATION
the superimposition of sine waves on electromagnetic carrier waves.
SATELLITE
a device that orbits the Earth and receives messages from one location and transmits them to another.
CHARGE-COUPLED DEVICE (CCD)
a very small solid state panel that contains light sensitive photo-sites or photo-diodes. The CCD uses the photo-sites to convert light into electrical signals transformed into an image.
GRAPHIC COMMUNICATIONS
the technology field focused on sending messages and other in formation using different means.
PRINCIPLES OF DESIGN
the formal rules that guide the design process.
DIGITAL WORK FLOW
the use of computers in each stage of the design process.
HOLOGRAPHY
the use of lasers to record realistic images of three-dimensional objects.
COMPUTER-AIDED DRAFTING (CAD)
the use of a computer system to produce technical drawings and/or design a product.
RAPID PROTOTYPING
the use of 3D CAD drawings to create real models of a product within a sort of time.
ENERGY
the capacity to do work or exert effort.
WORK
the use of force to act on an object in order to move move the object in the same direction as the force.
POTENTIAL ENERGY
stored energy or energy at rest.
KINETIC ENERGY
energy in motion.
POWER
the measure of work done over a period of time as energy is converted from one form to another or transferred from one place to another.
NUCLEAR FISSION
the splitting of the nucleus of an atom.
BIO-CONVERSION
a method of obtaining energy from waste products
GEOTHERMAL ENERGY
heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.
ELECTROLYSIS
the passage of electric current through an electrolytic fluid for the purpose of separating molecules.
LOAD
the amount of resistance the power system must overcome or, alternatively, the amount of force output by the power system: also can be referred to as weight or pressure.
MECHANICAL ADVANTAGE
the use of simple machines to multiply the output force of a mechanical system.
SIMPLE MACHINES
a device that creates a mechanical advantage. Complex machines are based on 6 simple machines in various combinations.
FLUID POWER
the use of pressurized liquid or gasses to control and transmit power.
BOYLE'S LAW
the law that states that if the pressure of a gas increases, the volume decreases (provided that the temperature remains constant).
DIRECT CURRENT (DC)
current flow in which electrons move in only one direction.
ALTERNATING CURRENT (AC)
current flow in which electrons reverse direction at regular intervals.
SERIES CIRCUIT
