Cache
A cache temporarily stores web pages you
have visited in your computer. A copy of documents you retrieve
is stored in cache. When you use GO, BACK, or any other means to
revisit a document, your browser first checks to see if it is in
cache and will retrieve it from there because it is much faster
than retrieving it from the server. If memory allocated to cache
in your computer becomes full, the browser discards older documents.
You can change the size of cache, although larger cache may affect
other operations and is limited by the amount of memory on your
computer.
Caching
Local storage of remote data designed
to reduce network transfers.
Cascading Style Sheets
CSS A mechanism that allows authors and
readers to attach the same style (e.g. fonts, colors and spacing)
to multiple HTML documents. The CSS language is human readable and
writeable, and expresses style in common desktop publishing terminology.
One of the fundamental features of CSS is that style sheets cascade;
authors can attach a preferred style sheet, while the reader may
have a personal style sheet to adjust for human or technological
handicaps.
Case Sensative
Capital letters (upper case) retrieve
only upper case. Most search tools are not case sensitive or only
respond to initial capitals, as in proper names. It is always safe
to key all lower case (no capitals), because lower case will always
retrieve upper case.
CGI
Common Gateway Interface :: the most common way Web programs interact
dynamically with users. Many search boxes and other applications
that result in a page with content tailored to the user's search
terms rely on CGI to process the data once it's submitted, to pass
it to a background program in JAVA, JAVASCRIPT, or another programming
language, and then to integrate the response into a display using
HTML.
CGI-BIN Script
CGI Binary script; a server-side program that accomplishes a task
that cannot be done using HTML. A means of extending the usefulness
and versatility of the Web enabling the display of dynamic content.
Client
An application or computer that receives
and interprets data sent by a matching server computer/application.
Client-server
Two computer systems linked by a network or modem connection where
the client computer uses resources by sending requests to the server
computer.
Client-side Imagemaps
A graphic with sub-areas that are linked
to different URLs. The MAP that relates parts of the image to different
URLs is stored in the current file. This saves a round trip to the
server, and should display pages faster. Destination URLs can be
displayed in the browser status line as the mouse selects portions
of the imagemap.
Cookie
A message from a WEB SERVER computer,
sent to and stored by your browser on your computer. When your computer
consults the originating server computer, the cookie is sent back
to the server, allowing it to respond to you according to the cookie's
contents. The main use for cookies is to provide customized Web
pages according to a profile of your interests. When you log onto
a "customize" type of invitation on a Web page and fill
in your name and other information, this may result in a cookie
on your computer which that Web page will access to appear to "know"
you and provide what you want. If you fill out these forms, you
may also receive e-mail and other solicitation independent of cookies.

Database
A database is a collection of information
stored oftentimes in a computerized format. A web browser can access
a public database by Perl scripts. There are many ways for a user
to find information in a database. Examples: library catalogs, search
engines, financial data, etc.
Design
The look, feel, and structure of a web site. It is the the synergy
and synthesis of three aspects: sensory, conceptual, and reactive.
Dial-up service
A common method of connecting to the Internet.
A user's modem dials up to a service provider, through which an
Internet connection is established.
DNS
Abbreviation for Domain Name System. A distributed client-server
database system which links domain names with their numerical IP
adresses.
DNS ENTRY
Domain Name Server entry :: frequently appears a browser error message
when you try to enter a URL. It refers to the initial part of a
URL, down to the first /, where the domain and name of the host
or SERVER computer are listed (most often in reversed order, name
first, then domain). This is translated in huge tables standardized
across the Internet into a numeric IP address unique the host computer
sought. These tables are maintained on computers called "Domain
Name Servers." Whenever you ask the browser to find a URL,
the browser must consult the table on the domain name server that
particular computer is networked to consult. If this look-up fails
for any reason, the "lacks DNS entry" error occurs. The
most common remedy is simply to try the URL again, when the domain
name server is less busy, and it will find the entry (the corresponding
numeric IP address). For more information, see "All About Domain
Names."
Domain
Hierarchical scheme for indicating logical and sometimes geographical
venue of a web-page from the network. In the US, common domains
are .edu (education), .gov (government agency), .net (network related),
.com (commercial), .org (non-profit and research organizations).
Outside the US, domains indicate country: ca (Canada), uk (United
Kingdom), au (Australia), jp (Japan), fr (France), etc. Neither
of these lists is exhaustive. See also DNS entry. To find out who
might own or be behind a domain, do a domaine look-up here
by doing a domaine name search.
Domain name
The name of a computer or server on the Internet in the form of
a string of names or numbers, separated by periods.
Example: www.adeptmultimedia.com
A domain name locates an organization or other entity
on the Internet and must be registered by an organization or entity.
For example the domaine name www.adeptmultimedia.com
is located at an Internet address at Internet point 201.0.5.2 and
a particular host server named "www". The "com"
part of the domain name reflects the purpose of the organization
(in this example, .com = "commercial") and is called the
top-level domain name. The "adeptmultimedia" part of the
domain name defines the organization or entity and together with
the top-level is called the second-level domain name. The second-level
domain name maps to and can be thought of as the "readable"
version of the Internet address.
A third level can be defined to identify a particular host server
at the Internet address. In our example, "www" is the
name of the server that handles Internet requests. (A second server
might be called "www2".) A third level of domain name
is not required. For example, the fully-qualified domain name could
have been "adeptmultimedia.com" and the server assumed.
Download
The transfer a file or files from a remote computer to the user's
computer.
DSL
Digital Subscriber Line - A family of digital telecommunications
protocols designed to allow high speed data communication over the
existing copper telephone lines between end-users (the consumer)
and telephone companies.
Dynamic HTML - DHTML
Allows a Web page to change after it's loaded into the browser --there
doesn't have to be any communication with the Web server for an
update. You can think of it as 'animated' HTML.
