A/S/L:
Age/Sex/Location. An acronym used in online chat, e-mail, and newsgroup postings. ACM:
Association for Computing Machinery .An international scientific and educational
organization dedicated to advancing the art, science, engineering, and application
of information technology. The ACM serves both professional and public interests
by fostering the open interchange of information and by promoting professional
and ethical standards.
ADC:
analog-to-digital converter .A hardware device that converts information from
analog to digital.
ADN:
Advanced Digital Network .Usually refers to a 56Kbps leased-line or dedicated
line.
ADO:
ADO stands for ActiveX Data Objects.
ADSL:
Asymmetric Digital Subscriber Line. A technology that allows more data to
be sent over existing copper telephone lines (POTS). ADSL supports data rates
of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and
from 16 to 640 Kbps when sending data (known as the upstream rate). ADSL requires
a special ADSL modem.
ASCII:
American Standard Code for Information Interchange.The world-wide standard
for the code numbers used by computers to represent all the upper and lower-case
Latin letters, numbers, punctuation, etc. There are 128 standard ASCII codes,
each of which can be represented by a 7 digit binary number: 0000000 through
1111111. This is also used to describe files that are stored in clear text
format.
APNIC:
APNIC is one of three Regional Internet Registries currently operating in
the world. It provides allocation and registration services which support the
operation of the Internet globally. It is a not-for-profit, membership-based
organisation whose members include Internet Service Providers, National Internet
Registries, and similar organisations. APNIC represents the Asia Pacific region,
comprising 62 economies.
AUP:
Short for acceptable use policy. Also known as TOS (Terms of Service). A contract
specifying what a subscriber can and cannot do while using an ISP's service.
Contains things like liability disclaimers, lists of actions or behavior that
will result in the termination of a customers account, definition of terms
such as "unlimited use," billing policies, SPAM clauses, etc.
BBS:
(Bulletin Board System) -- A computerized meeting and announcement system
that allows people to carry on discussions, upload and download files, and
make announcements without the people being connected to the computer at the
same time. There are many thousands (millions?) of BBS’s around the world, most
are very small, running on a single IBM clone PC with 1 or 2 phone lines.
Some are very large and the line between a BBS and a system like CompuServe
gets crossed at some point, but it is not clearly drawn.
BIT:
The basic unit of information in a binary numbering system. The electronic
circuitry in computers detect the difference between two states (high current
and low current) and represents these two states as one of two numbers 1 or
0. This basic high/low, either/or, yes/no units of information are called
bits. Eight bits comprise what is called an octet, sometimes referred to as
a byte. The word bit derives from the phrase Binary digit.
BMP:
A Microsoft Windows image format. The images you see when Windows starts
up and closes, and the wallpaper that adorns your desktop, are all in BMP
or bitmap format.
BPS:
(Bits-Per-Second) -- A measurement of how fast data is moved from one place
to another. A 28.8 modem can move 28,800 bits per second.
BTW:
(By The Way) -- A shorthand appended to a comment written in an online forum.
BYTE:
A set of Bits that represent a single character. Usually there are 8 Bits in a
Byte, sometimes more, depending on how the measurement is being made
CBT:
Computer Based Training. CDF:
Short for channel definition format, a specification developed by Microsoft that
allows Web publishers to push content at users. The Channel Definition Format
is an open specification that permits a web publisher to offer frequently
updated collections of information, or channels, from any web server for automatic
delivery to compatible receiver programs on PCs or other information appliances.
.
CERN:
CERN is the European Organization for Nuclear Research, the world's largest
particle physics centre. Founded in 1954, the laboratory was one of Europe's
first joint ventures, and has become a shining example of international collaboration.
From the original 12 signatories of the CERN convention, membership has grown
to the present 20 Member States.CERN explores what matter is made of, and
what forces hold it together.The Laboratory provides state-of-the-art scientific
facilities for researchers to use. These are accelerators which accelerate
tiny particles to a fraction under the speed of light, and detectors to make
the particles visible. CLEC:
In the United States, a CLEC (competitive local exchange carrier) is a company
that competes with the already established local telephone business by providing
its own network and switching. The term distinguishes new or potential competitors
from established local exchange carriers (LEC) and arises from the Telecommunications
Act of 1996, which was intended to promote competition among both long-distance
and local phone service providers.
CRM:
Acronym for Customer Relationship Management. CRM entails all aspects of interaction
a company has with its customer, whether it be sales or service related. Computerization
has changed the way companies are approaching their CRM strategies because
it has also changed consumer buying behavior. With each new advance in technology,
especially the proliferation of self-service channels like the Web and WAP phones,
more of the relationship is being managed electronically. Organizations are
therefore looking for ways to personalize online experiences (a process also referred
to as mass customization) through tools such as help-desk software, e-mail
organizers and Web development apps.
C++:
A programming language designed by Dennis Ritchie at AT&T Bell Labs ca. 1972
for systems programming on the PDP-11 and immediately used to reimplement
UNIX. It was called "C" because many features derived from an earlier compiler
named "B" in commemoration of *its* parent, BCPL. In fact, C was briefly named
"NB". Before Bjarne Stroustrup settled the question by designing C++, there was
a humorous debate over whether C’s successor should be named "D" or "P" (following
B and C in "BCPL").
CFML:
Cold Fusion Markup Language. An extension of HTML. A proprietary markup language
developed by the Allaire Corporation and for use with Allaire’s Cold Fusion Application
Server. CFML tags link HTML pages to database servers. CFML goes beyond database
management to fill some important gaps in HTML, including session variables,
branching logic, loops, and other constructs that programmers are accustomed to
using, such as error trapping and debugging tools.
CGI:
Common Gateway Interface .An HTTP server is often used as a gateway to a legacy
information system; for example, an existing body of documents or an existing
database application. The Common Gateway Interface is an agreement between HTTP
server implementors about how to integrate such gateway scripts and programs.It
is typically used in conjunction with HTML forms to build database applications.
COM:
Although it’s in all capital letters, COM is not an acronym. It’s a contraction
of communications, and it’s used to describe the serial port on a PC. COM
is generally used in conjunction with a number, as in COM1, COM2, COM3, or
COM4 (for exampe, a printer port).
CPU:
Abbreviation for Central Processing Unit. The main component in a computer's microprocessor
which performs calculations and executes instructions.
CRC:
Cyclical Redundancy Check. A mathematical technique used to check for errors when
sending data by modem. Because some phone lines are notoriously crackly and can
cause breaks in transmission, this is a crucial step. If the CRC fails to add
up, the receiving end of a data transmission sends a NAK (negative acknowledgement
or "say that again") signal until it does add up. CRCs are also used in tape
backups and other streaming communications.
CTS:
Clear To Send. One of the nine wires in a serial port used in modem communications,
CTS carries a signal from the modem to the computer saying, "I’m ready to
start when you are."
DHTML:
dynamic HTML.The W3C may not have an official definition for it, but dynamic
HTML combines HTML, style sheets, and scripts to make Web pages more interactive.
It sounds great. But while both Microsoft Internet Explorer 4.0 and Netscape Communicator
4.0 support dynamic HTML features, they do so in different--and incompatible--ways.
The companies say they will work to make their browsers compatible with whatever
specification the W3C finally decides upon. However, the browsers may be in
their fifth generation before users see a concrete standard.
DLL:
Dynamic Link Library.A Windows platform file that is actually an executable mini-program
itself that is NOT executed directly by a user but by a running program or
application.
DPI:
Dots Per Inch. Metrics used to measure print and screen resolution.
DSS:
Digital Signature Standard. Digital signature technology is used to confirm
the identity of a sender of electronic information and to verify that the data
has not been altered. The National Institute of Standards and Technology recently
ended a 10-year battle between the federal government and commercial digital
signature makers when it announced that agencies may begin using the most
popular commercial digital signature technology on the market.
DNS:
The Domain Name System (DNS) is a distributed Internet directory service. DNS
is used mostly to translate between domain names and IP addresses, and to
control Internet email delivery. Most Internet services rely on DNS to work, and
if DNS fails, web sites cannot be located and email delivery stalls. DOM:
The Document Object Model is a platform- and language-neutral interface that
will allow programs and scripts to dynamically access and update the content,
structure and style of documents. The document can be further processed and
the results of that processing can be incorporated back into the presented
page.
EBPP:
On the Internet, electronic bill presentment and payment (EBPP) is a process that
enables bills to be created, delivered, and paid over the Internet. The service
has applications for many industries, from financial service providers to
telecommunications companies and utilities. Although buying products over
the Internet with a credit card has become a common occurrence, viewing the
credit card bill itself - and making payments to settle the bill electronically
- has not. This is expected to dramatically change as new EBPP products are
introduced that include features such as secure e-mail delivery, and also
as EBPP technology becomes more common in business-to-business e-commerce.
FTP:
File Transfer Protocol.The common procedure used for downloading and uploading
files over the Internet. With FTP you can login to another Internet site and
transfer (meaning, send or receive) files. Some sites have public file archives
that you can access by using FTP with the account name "anonymous" and your
e-mail address as the password.
FAQ:
Pronounced as separate letters or as fak, and short for frequently asked questions,
a FAQ is a document that answers questions about some technical topic. Frequently,
FAQs are formatted as help files or hypertext documents
GIF:
Graphics Interchange Format. Most color images and backgrounds on the Web are
GIF files. This compact file format is ideal for graphics that use only a few
colors, and it was once the most popular format for online color photos. However,
GIF has lost ground to the JPEG format when it comes to photos. GIF images
are limited to 256 colors, but JPEGs can contain up to 16 million colors--and
they can look almost as good as a photograph.CompuServe developed GIF in 1987,
calling it GIF87, and two years later added new features such as interlacing,
transparency, and animation to create the format known as GIF89a. People don't
usually distinguish between the two GIF versions, so if someone refers to
an image as a "GIF89" rather than simply a "GIF," it's probably animated.
HTML:
Hypertext Markup Language. As its name suggests, HTML is a collection of formatting
commands that create hypertext documents--Web pages, to be exact. When you
point your Web browser to a URL, the browser interprets the HTML commands
embedded in the page and uses them to format the page's text and graphic elements.
HTML commands cover many types of text formatting (bold and italic text, lists,
headline fonts in various sizes, and so on), and also have the ability to
include graphics and other nontext elements.
HTTP:
Hypertext Transfer Protocol .The protocol used to transmit and receive all data
over the World Wide Web. When you type a URL into your browser, you're actually
sending an HTTP request to a Web server for a page of information (that's
why URLs all begin with "http://"). HTTP1.1, the latest version, is currently
undergoing revisions to make it work more efficiently with TCP/IP.
ICANN:
The Internet Corporation for Assigned Names and Numbers (ICANN) is a technical
coordination body for the Internet. Created in October 1998 by a broad coalition
of the Internet's business, technical, academic, and user communities, ICANN
is assuming responsibility for a set of technical functions previously performed
under U.S. government contract by IANA and other groups.
ICQ:
I Seek You. A user-friendly Internet program that tells you who's online at all
times. No longer will you search in vain for friends and associates on the Net.
ICQ does the searching for you, alerting you in real time when friends or
colleagues sign on. With ICQ, you can chat, send messages and files, play
games, or just hang out with your fellow citizens as you surf the Net.
ILEC:
An ILEC (incumbent local exchange carrier) is a telephone company in the
U.S. that was providing local service when the Telecommunications Act of 1996
was enacted. ILECs include the former Bell operating companies (BOCs) which were
grouped into holding companies known collectively as the regional Bell operating
companies (RBOCs) when the Bell System was broken up by a 1983 consent decree.
ILECs are in contradistinction to CLEC (competitive local exchange carriers).
IRC:
Internet Relay Chat .IRC is a way of hooking up with other Net users to exchange
written comments--live and in real time. To do this, you need an IRC client
and an IRC server. Once connected to the server, you join a channel, or discussion
group, which can include people from all over the world. IRC channels may
hold discussions about anything under the sun (and some topics that shouldn't
see the light of day).
ISDN:
Integrated Services Digital Network (ISDN) is comprised of digital telephony
and data-transport services offered by regional telephone carriers. ISDN involves
the digitalization of the telephone network, which permits voice, data, text,
graphics, music, video, and other source material to be transmitted over existing
telephone. The emergence of ISDN represents an effort to standardize subscriber
services, user/network interfaces, and network and internetwork capabilities.
ISDN applications include high-speed image applications (such as Group IV
facsimile), additional telephone lines in homes to serve the telecommuting
industry, high-speed file transfer, and video conferencing.
JPEG:
JPEG (pronounced "jay-peg") is a standardized image compression mechanism. JPEG
stands for Joint Photographic Experts Group, the original name of the committee
that wrote the standard.JPEG is designed for compressing either full-color or
gray-scale images of natural, real-world scenes. It works well on photographs,
naturalistic artwork, and similar material; not so well on lettering, simple
cartoons, or line drawings. JPEG handles only still images.
LAN:
A local area network (LAN) is a group of computers and associated devices
that share a common communications line and typically share the resources
of a single processor or server within a small geographic area (for example,
within an office building). Usually, the server has applications and data
storage that are shared in common by multiple computer users. A local area
network may serve as few as two or three users (for example, in a home network)
or many as thousands of users (for example, in an FDDI network).
