asynchronous: in electronic learning, instructors are commonly as little as a few minutes or as long as weeks apart at the time of broadcast. Interaction is happening with computer program rather than live instruction.
synchronous
: this type of electronic learning sets a time when instruction will meet
class for discussion at a specific time. This type of learning is more
interactive.
Anthropology - The body of knowledge available to a civilization that is of use in fashioning implements, practicing manual arts and skills, and extracting or collecting materials. Technology is not an independent science, having a set of doctrines of its own, but consists of applications of the principles established in the various physical sciences (chemistry, mechanics, mineralogy, etc.) to manufacturing processes.
Compression - The act of compressing, or state of being compressed. The coding of data to save storage space or transmission time. Although data is already coded in digital form for computer processing, it can often be coded more efficiently (using fewer bits).
Incorporate - To unite (one thing) with something else already in existence.
Moving
Picture Experts Group - An ISO committee that generates standards for digital
video compression and audio. Also the name of their algorithms.MPEG-1 is
optimized for CD-ROM and is the basis for MP3. MPEG-2 is aimed at broadcast
quality video for applications such as digital television set-top boxes
and DVD. MPEG-4 is a standard for low bandwidth video
telephony
and multimedia on the Worldwide Web. MPEG-3 was merged into MPEG-2.
Sequel - a continuation that follows something like a book or a movie.
simulation - Representation of the operation or features of one process or system through the use of another: computer simulation of an in-flight emergency. An imitation.
Technology - The application of science, especially to industrial or commercial objectives.The scientific method and material used to achieve a commercial or industrial objective.
Virtual Reality - A computer simulation of a real or imaginary system that enables a user to perform operations on the simulated system and shows the effects in real time.A hypothetical three-dimensional visual world created by a computer; user wears special goggles and fiber optic gloves etc., and can enter and move about in this world and interact with objects as if inside it.
Antenna - A device used to transmit and receive radio, television, microwave telephone, and radar signals.
Base Station - The piece of a cordless phone which is connected to the phone service. It receives the calls from the phone line, converts them into FM radio signals and sends them to the cordless phone.
Caller ID - A feature on a telephone that lets you know the phone number, and sometimes the name, of the caller before you pick up the phone.
Call Waiting - A feature on a telephone that lets you receive another call when you are already talking on the phone.
Cells - Small areas into which a larger area (city or town) is divided for cellular telephones. Each cell has a radius of about 1.5 to 2.4 km (1 to 2.5 mi) and is equipped with a radio transmitter that employs its own range of radio frequencies. The same range can be repeated several times across a large city as long as the cells using them are not neighbors. As a cellular telephone moves through this pattern of cells, its user's calls are switched from one cell to the next by a computerized system. This allows many more users to use the system.
Digital Cameras - Cameras which store their images on digital media, such as diskettes or computer hard disks, instead of film.
Electromagnetism - Magnetism produced by electric charge in motion.
Fiber Optic Cables - Cables containing many extremely thin glass fibers. The glass fibers carry telephone signals which are sent over pulse of light produced by lasers. These cables can carry many more calls than microwave or satellite links.
Frequencies - The number of repetitions per unit time of a complete waveform, as of an electric current or sound wave. Radio waves are described in terms of their frequencies.
Global Positioning Systems (GPs) - A system of satellites which allows anyone with a GPs device to determine their location anywhere on earth. This is used for mapping and route planning systems.
Internet - A worldwide network of computers and communications systems which allows users to share information.
IP (Internet Protocol) Telephony - The ability to send and receive telephone conversations over the Internet, instead of using the telephone network.
Microwave Radio Waves - high-frequency electromagnetic waves, used to carry long-distance telephone conversations.
Protocol - An industry established method of handling information.
Radio Telephones - The first system of mobile communications. It had one central tower per city and up to 25 channels for communications. The transmitter in each car needed to be powerful enough to transmit 40 or 50 miles. There were not enough channels for many people to use this system.
Satellites - Objects launched to orbit Earth, used for long distance communications such as television and radio broadcasts, and telephone calls.
Share the Frequencies - methods, such as Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA) that allow more than one call to share the same frequency at the same time. This is done by either giving each call a certain portion of time on the frequency or spreading each call over the available frequencies. This allows many more callers to use the cellular phone system.
Speaker Phones - A type of telephone that lets you speak and hear without having to use the handset. Also called "hands-free" operation.
Synchronizing - Causing to occur or operate at the same time as something else, to match exactly. Computers and PDAs are synchronized so that the information on each is always the same. WAP - Wireless Access Protocol. A communications standard which allows wireless devices such as cellular phones and PDAs to access the Internet. Web pages must be changed to be used by these devices because most don't support graphics and multimedia, and have much smaller screens.
Transmitter - An electronic device that generates and amplifies a carrier wave, modulates it with a meaningful signal derived from speech or other sources, and radiates the resulting signal from an antenna.
Voice Recognition - Computer systems which can convert spoken language into text, or commands recognized by the system. Morse code - set of signals, developed by Samuel Morse, used on the telegraph and in some radio transmissions, to send messages.
Asexual reproduction -The act or process of reproducing; the state of being reproduced; the process by which plants and animals give rise to offspring. There are two distinct methods of reproduction; asexual reproduction and sexual.
Breeding - To produce (offspring); give birth to or hatch.
DNA - A nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA. DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. The sequence of nucleotides determines individual hereditary characteristics.
Electrons - A stable subatomic particle having a rest mass of 9.1066 × 10-28 gram and a unit negative electric charge of approximately 1.602 × 10-19 coulomb.
Embryo: An organism in its early stages of development, especially before it has reached a distinctively recognizable form.
Gene: A hereditary unit that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes exist in a number of different forms and can undergo mutation.
Genetics - The branch of biology that deals with heredity, especially the mechanisms of hereditary transmission and the variation of inherited characteristics among similar or related organisms.
lacerations - cuts.
Laser - Any of several devices that convert electromagnetic radiation of mixed frequencies to one or more discrete frequencies of highly amplified and coherent ultraviolet, visible, or infrared radiation. A device whose output is in an invisible region of the electromagnetic spectrum.
Method: A way of doing something.
Mutation - A sudden structural change within a gene or chromosome of an organism resulting in the creation of a new character or trait not found in the parental type.
Organisms: An individual form of life, such as a plant, an animal, a bacterium, a protist, or a fungus; a body made up of organs, organelles, or other parts that work together to carry on the various processes of life.
Procedure: The steps in a experiment or plan.
Reproduction (gamogenesis): In both cases the new individual is developed from detached portions of the parent organism. In asexual reproduction, the detached portions of the organism develop into new individuals without the intervention of other living matter. In sexual reproduction, the detached portion, which is always a single cell, called the female germ cell, is acted upon by another portion of living matter,and in the fusion of the two (impregnation) a new cell is formed.
wash
out and perfusion: This is a five-step procedure in which the blood is
replaced with a glycerin-based solution that helps minimize the freezing
damage.
