Glossary

Module 1

Audio Tape
A device used to capture sounds magnetically. Usually a strip of material like Acetate coated with some type of magnetizable material like Iron Oxide.
Cathode
A negative electrode
CD
Compact Disc; Used to capture sound, or other information digitally. It is composed of a clear plastic covered with a thin layer of acrylic resin. Information is stored by making patterns of small pits within the plastic. The patterns are read by a laser beam and turned into there original form.
Computer
A device which is capable of performing mathematical operations.
CPU
Central Processing Unit, where most of the mathematical calculation in a computer are carried out.
Digital Audio
Digital audio is the term used to describe a sound that is stored digitally, using numbers. The voice on this CD is an example of digital audio.
DVD
digital video disk - high density data storage mechanism particularly useful for storing video data
Electrode
A conductor through which electricity leaves or enters as an electrolyte, gas or vacuum.
HDTV
High definition television, is a digital television broadcastin system
Hypertext
Text displayed on a screen which when chosen (ie clicked on) links to new text.
Infrared
A term used to desribe light wavelengths below those that humans can normally see.
LAN
Local area network, is a network of connected computers within a relatively small area such as a classroom or building.
MIDI
Musical Instrument Digital Interface is a protocol that allows computers and musical instruments such as sound synthesizers to communicate with one another. Midi is not to be confused with digital sound, it is instead the map of digital sound.
Multimedia
The word currently used to describe the processes which combine several media types.
Peripheral
A device used to extend the capabilities of a computer, but that is not part of the computer (ie a printer).
Photography
The art of producing pictures by the chemical action of light on a sensitive plate of film.
Ram
Random Access Memory, you are able to read from or write to ram
Register
shift registers are charge storage devices that store series of 1's or 0's. These registers along with flip flops are fundamental to the functioning of digital devices such as computers.
Rom
Read-Only memory
Telephone
technology used for communication
Ultraviolet
A term used to describe light wavelenths above those that humans can normally see.
WAN
Wide area network, is a large network of computers, a WAN is often comprised of several LANs

Module 2

Cerebrum
The largest part of the brain, responsible for sensory responses, motor responses, communication, behaviour, and emotion
Cerebellum
Located beneath the Cerebrum, controls muscle movement, coordination, and balance.
Brain Stem
Lies below the hypothalamus and thalamus. It is made up of the midbrain, pons, and medulla.
Neurons
A nerve cell and all it's processes
Behaviourist Theory
The behaviourist theory of learning focuses on respondent and operant conditioning. To a behaviourist, learning is a matter of stimulus and response.
Constructivist Theory
The constructivist theory of learning focuses on placing a student in a situation in which learning may occur from direct experience or the shared experience of an expert's knowledge.
Cognitive Theory
The idea that we learn by associating new with something we already know which is meaningful to us (meaningful learning).

Module 3

NLP
Natural Language Processing, the process by which a computer translates words into ideas by examining patterns and phrases
GIS
Geographic Information System, software that can assemble, store, manipulate, and display computer-generated maps.

Module 4

Cognitive State of being able to perceive objects or to remember ideas.
Equation The act of making equal; allowance for any inaccuracies.
Simulation To assume the mere appearance of, without the reality.
Variable That which is subject to change; capable of being adapted.
Behaviourist The behaviourist theory of learning focuses on respondent and operant conditioning. To a behaviourist, learning is a matter of stimulus and response.
Constructivist The constructivist theory of learning focuses on placing a student in a situation in which learning may occur from direct experience or the shared experience of an expert's knowledge.

Module 5

World-Wide Web A hypertext based process that put Internet information on to linked pages accessible at the click of a mouse button.
ISDN (Integrated Services Digital Network) A type of connection to the internet that allows for much higher speeds than a traditional modem/phone line.
IRC Internet Relay Chat, a protocol used for people to communicate in real-time via the internet.
TCP/IP Transmission Control Protocol/Internet Protocol, an agreed method for sending and recieving messages among many different computers and systems.
FTP File Transfer Protocol, FTP makes it possible for you to obtain a wide variety of files and programs from the Internet.
LAN Local Area Network
WAN Wide Area Network
Telnet Enables one computer to communicate with or control another computer.

Module 6

ETV Educational Television Laser Disc A disc similar to a CD but larger that was used to store much greater amounts of data like movies.
Transistor Developed in the 1960's the transistor replace vacuum tubes and allowed for much smaller more effecient electronic devices.
A.M. Amplitude Modulation
FM Frequency Modulation
Watt A unit of power equal to the rate of working of one joule per second
Joule The work done by a current of one ampere flowing for one second against a resistance of one Ohm.
Ampere An ampere is a fundamental unit of current.
Ohm An Ohm is a unit of resistance.
