to view PDF (portable document format) files in their original format
and appearance. Documents saved as pdf files retain all there special
formatting characteristics and layout properties. If you would like

to investigate pdf file format. The Acrobat Reader is free and can be
downloaded from Adobe.
Applet:

A small Java program that can be embedded in an HTML page.
Asynchronous:
[return to top]
Not at the same time. In an online context this term is generally used
to describe various forms of communication in which participants do
not have to be available at the same time (as opposed to synchronous).
In online teaching, examples of common asynchronous communication includes
threaded discussion (bulletin/conference) boards and email.
B
Bandwidth:
[return to top]
Measured in Hertz (Hz). In terms of the Web it is the amount of data,
usually measured in bits per second, that can be sent through a given
communications channel. Bandwidth must be considered when designing
Web pages as the increased requirement for bandwidth translates to increased
download time for the end user. Media rich Web documents often require
high bandwidth.
Bookmark:
[return to top]
A feature of most
Web browsers (called Favorites in Internet Explorer) that allows you
to save frequently accessed web pages (URLs) in a special file that
can be easily accessed.
Browser:
[return to top]
A client (resides on the users machine) software program
which allow htm(l) (web pages) to be viewed. Common browsers are Netscape
and Internet Explorer. Browser software resides on the client (users)
machine.
Bulletin Board: [return to top]
One of the many names (others include conference board and
discussion board) where asynchronous text-based online communication
can occur. Many bulletin boards provide the ability for users to have
threaded discussions about specific topics.
C
Cache: [return to top]
Browsers such as Netscape and Microsoft Internet Explorer hold copies
of recently visited web files in disk memory called the cache.
Caching files in
memory provides for quicker loading of files than if they are always
transferred from the Web. A disadvantage of caching files is that sometimes
older versions of a file loads from your computer when a newer version
of the file is available on the Web. This can be particularity confusing
if you are making changes to your website.
Use your browser's
Refresh or Reload buttons to check for more current versions of Web
pages (try this before you panic).

Room: [return to top]

gather to chat about various subjects. As you type, everything you type
is displayed to the other members of the chat group. Some online instructors
use a chat room to provide online "office hours". Students
may also use a chatroom to discuss group projects or to schedule study
group meetings.
Computer Conferencing: [return to top]
Interactive communication between networked computers in which data
is shared. Data may take the form of audio (e.g. Firetalk meetings),
text (conference/bulletin board discussions), email, video conferencing,
etc. This type of conferencing can happen in "real time",
which means the messages appear as they are being typed, or they can
happen asynchronously with the messages being stored for later use.
Examples of Web-based
computer conferencing includes threaded discussions, whiteboards, chat
rooms, NetMeetings, Firetalk meetings, etc.
