Glossary

 

A

Applet 
A small program or application that runs on a browser and enables additional features like animation.

Audio Conferencing 
Voice communication delivered through standard telephone lines or Internet-based software sometimes used in distance learning.


B

Bandwidth 
Refers the capacity of a connection to transport digital content. It is usually measured in transfer speed (bits-per-second). Generally speaking, text transfers more quickly and requires less bandwidth than audio or video. Very effective compression can change that somewhat.

Blackboard Academic Suite 
A comprehensive and flexible e-Learning software platform that delivers a complete course management system

Broadband
 
As opposed to the connection speeds and capacity that one can obtain over a phone line with a modem, a broadband connection can accommodate the rapid transfer of large amounts or packets of information. Generally, Internet connections provided by cable or DSL are broadband. Most distance learning courses will recommend that you have a broadband connection.
 

Browser 
Software that allows you to access view Web sites on the Internet from your PC, laptop, or handheld PDA. Examples of browsers include Firefox, Internet Explorer, Mozilla, Opera, and Safari.

BBS (bulletin board system)

CD-ROM (compact disk read-only memory) 
An electronic data storage medium that uses optical technology for storing and playing back audio, video, text, and other information in digital form.

Chat 
An online, real-time interactive communication method using text to send and receive instant messages.

Cookie 
A small text file placed on your hard by a web site to record information about you. When you return, your computer serves up the "cookie" to the web site and previously recorded information such as your name, site login/password, preferences, shopping cart info, and more are passed along. The web page is then customized based on that information.

The method of getting information to the user via Internet, CD-ROM, books, instructors, and other mediums.

Dial-up 
An Internet connection achieved through telephone lines using a modem.

DSL (digital subscriber line) 
An Internet access method for high-speed data transfer over telephone lines.

DVD (digital versatile disk) 
An electronic data storage medium that uses optical technology for storing and playing back audio, video, text, and other information in digital form, but with far greater capacity than CDs.


E

E-Learning 
Any learning that utilizes a network (LAN, WAN or Internet) for delivery, interaction, or facilitation. This would include distributed learning , distance learning (other than pure correspondence ), CBT delivered over a network, and WBT . Can be synchronous , asynchronous , instructor-led or computer-based or a combination.

HTTP 
Abbreviation for "HyperText Transfer Protocol." An Internet protocol that is used by a web server and a web browser to transfer data (such as text, images, sound, video, and other multimedia files) between them. When you enter a URL in your web browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested web page.

Hybrid courses 
Hybrid courses blend face-to-face interaction such as in-class discussions, active group work, and live lectures with typically web-based educational technologies such as online course cartridges, assignments, discussion boards, and other web-assisted learning tools. The degree to which the design of hybrid courses utilize traditional classroom and online learning environments varies, being largely dependent on the subject matter and overall nature of a course.
