Glossary of Internet Terms and Phrases
WAIS (Wide Area Information Servers)
- A distributed information retrieval system. WAIS is supported by Apple
Computer, Thinking Machines and Dow Jones. Clients are able to retrieve
documents using keywords. The search returns a list of documents, ranked
according to the frequency of occurrence of the keyword(s) used in the
search. The client can retrieve text or multimedia documents stored on the
server. WAIS offers simple natural language input, indexed searching for
fast retrieval, and a "relevance feedback" mechanism which allows the
results of initial searches to influence future searches. It uses the ANSI
Z39.50 service. Public domain implementations are available.
Other information retrieval systems include archie, Gopher, Prospero, and
WAN (Wide Area Network)
- A communications
network that uses such devices as telephone lines, satellite dishes, or
radio waves to span a larger geographic area than can be covered by a
- A document on the
World Wide Web, consisting of an
HTML file and any related files for scripts and graphics, and often
hyperlinked to other documents on the Web.

Web Server Logs
- A file that lists actions that have occurred. For example,
Web servers maintain log files listing every request made to the server.
With log file analysis tools, it's possible to get a good idea of where
visitors are coming from, how often they return, and how they navigate
through a site. Using
cookies enables Webmasters to log even more detailed information about
how individual users are accessing site.
HTTP Server. A server process running at a
web site which sends out web pages in response to HTTP requests from
If one site runs more than one server they must use different port numbers.
Alternatively, several hostnames may be mapped to the same computer in which
case they are known as "virtual servers".
HTTPd are two popular web servers. There are many others including some
for practically every
platform. Servers differ mostly in the "server-side" features they offer
server-side include, and in their authentication and access control
mechanisms. All decent servers support
and most have some binary API as well.
Services by Light Speed Networks
- A family of standards promoted by the W3C for working with other
business, developers and programs through open
languages and APIs, including
Simple Object Access Protocol, WSDL and UDDI.
- A set of interconnected
webpages, usually including a
homepage, generally located on the same
server, and prepared and maintained as a collection of information by a
person, group, or organization.

- (Windows New Technology, NT) Microsoft's 32-bit
operating system developed from what was originally intended to be OS/2
3.0 before Microsoft and IBM ceased joint development of OS/2. NT was
designed for high end workstations (Windows NT 3.1),
servers (Windows NT 3.1 Advanced Server), and corporate
networks (NT 4.0 Enterprise Server). The first release was Windows NT
Unlike Windows 3.1, which was a graphical environment that ran on top of
MS-DOS, Windows NT is a complete operating system. To the user it looks like
Windows 3.1, but it has true multi-threading, built in networking, security,
and memory protection.
It is based on a microkernel, with 32-bit addressing for up to 4Gb of RAM,
virtualised hardware access to fully protect applications, installable file
systems, such as FAT, HPFS and NTFS, built-in networking, multi-processor
support, and C2 security.
NT is also designed to be hardware independent. Once the machine specific
part - the Hardware Abstraction Layer (HAL) - has been ported to a
particular machine, the rest of the operating system should theorertically
compile without alteration. A version of NT for DEC's Alpha machines was
planned (September 1993).
NT needs a fast 386 or equivalent, at least 12MB of RAM (preferably 16MB)
and at least 75MB of free disk space.
NT 4.0 was followed by Windows 2000.
- The defined series of tasks within an organization to produce a final
outcome. Sophisticated workgroup computing applications allow you to define
different workflows for different types of jobs. At each stage in the
workflow, one individual or group is responsible for a specific task. Once
the task is complete, the workflow software ensures that the individuals
responsible for the next task are notified and receive the data they need to
execute their stage of the process. Workflow is built into most
document management and
content management systems so that content is approved before being
posted to the

World Wide Web
- The complete set of documents or collection of internet sites residing
Internet servers that use the
HTTP protocol, accessible to users via a simple point-and-click system.
- Describes a user interface under which "What You See Is What You Get",
as opposed to one that uses more-or-less obscure commands that do not result
in immediate visual feedback. True WYSIWYG in environments supporting
multiple fonts or graphics is a a rarely-attained ideal; there are variants
of this term to express real-world manifestations including WYSIAWYG (What
You See Is _Almost_ What You Get) and WYSIMOLWYG (What You See Is More or
Less What You Get). All these can be mildly derogatory, as they are often
used to refer to dumbed-down user-friendly interfaces targeted at
non-programmers; a hacker has no fear of obscure commands (compare WYSIAYG).
On the other hand, EMACS was one of the very first WYSIWYG editors,
replacing (actually, at first overlaying) the extremely obscure,
