MAPI:
Messaging Application Programming Interface. A messaging architecture and
a client interface component for applications such as electronic mail, scheduling,
calendaring and document management. As a messaging architecture, MAPI provides
a consistent interface for multiple application programs to interact with
multiple messaging systems across a variety of hardware platforms. MIDI:
Musical Instrument Digital Interface. MIDI is a method of communication between
digital instruments, usually synthesizers. It allows one synthesizer to send
performance information to the synthesis engine of the other. It stands for
Musical Instrument Digital Interface, and was created in 1982.
MISF:
The Microsoft Internet Security Framework provides a comprehensive set of
public key security technologies that meet the needs of business, developers,
and users for secure exchange of information across public networks, access
control to resources and information, and electronic commerce.
MMX:
A technology developed by the Intel Corporation which is the next step after the
famed Pentium Proccessor. This new CPU chip will enable greater handling of multimedia
such as video and audio on the desktop as well as over the Internet.
MP3:
MP3 is short for MPEG Audio Layer 3, a compression method that allows for CD
quality sound and a very small file size. When people say "MP3s", they are
referring to sound files compressed in the MP3 format - usually music. MP3 generally
gets a bad rap because it is most often associated with people who have abused
this technology by recording CD tracks and posting them on web sites or trading
them on FTPs.
MPEG:
MPEG (Moving Pictures Experts Group) is a group of people that meet under
ISO (the International Standards Organization) to generate standards for digital
video (sequences of images in time) and audio compression. In particular,
they define a compressed bit stream, which implicitly defines a decompressor.
However, the compression algorithms are up to the individual manufacturers, and
that is where proprietary advantage is obtained within the scope of a publicly
available international standard.
MIME:
MIME means Multipurpose Internet Mail Extensions, and refers to an official
Internet standard that specifies how messages must be formatted so that they can
be exchanged between different email systems. MIME is a very flexible format,
permitting one to include virtually any type of file or document in an email
message. Specifically, MIME messages can contain text, images, audio, video,
or other application-specific data. MGCP:
The Media Gateway Control Protocol, developed by Telcordia and Level 3 Communications,
is one of a few proposed control and signal standards to compete with the
older H.323 standard for the conversion of audio signals carried on telephone
circuits (PSTN ) to data packets carried over the Internet or other packet networks.
NCSA:
The National Center for Supercomputing Applications (NCSA) at the University of
Illinois at Urbana- Champaign is the leading-edge site for the National Computational
Science Alliance (Alliance). In this capacity, NCSA anchors all Alliance teams
and oversees the administration of all Alliance programs. NCSA leads the Alliance
in its mission to maintain American preeminence in science and technology.
NNTP:
Network News Transfer Protocol. A protocol for the distribution, inquiry, retrieval,
and posting of news articles. To configure your Web browser or newsgroup reader
software to connect to a news server you need to specify the NNTP server. NOC:
Network Operations Center. Responsible for the day-to-day operations of the
Internet's component networks.
NTFS:
NT File System.One of the file systems for the Windows NT operating system
(Windows NT also supports the FAT file system). NTFS has features to improve
reliability, such as transaction logs to help recover from disk failures. To
control access to files, you can set permissions for directories and/or individual
files. NTFS files are not accessible from other operating systems such as DOS.
OS:
Operating System. The low-level software which schedules tasks, allocates storage,
handles the interface to peripheral hardware and presents a default interface
to the user when no application program is running.
OSP:
Online Service Provider. A company that provides customer only content to
subscribers of their service. Most OSPs now offer Internet access, but their main
feature is the privately maintained network that is only accessible to their customers.
This network is not part of the Internet, although some OSPs are currently
making some content available on the Web. Because OSPs control the structure
and content of their networks, they are more logical and user-friendly environments
especially for beginners. The most popular OSPs are: AOL (America Online),
CompuServe, MSN, and Prodigy.
P3P:
P3P is the "Platform for Privacy Preferences," a new Internet protocol being developed
by the World Wide Web Consortium (W3C). Protocols are the rules around which
Internet software is developed. This means that the P3P functions will be
implemented as part of the functioning of the World Wide Web, and most likely
it will be intergrated into Web browsers like Netscape and Internet Explorer.
P3P defines a standard way that the privacy practices of Web sites can be defined
and that a consumer's personal data can be requested.
PNG:
PNG is an extensible file format for the lossless, portable, well-compressed
storage of raster images. PNG provides a patent-free replacement for GIF and can
also replace many common uses of TIFF. Indexed-color, grayscale, and truecolor
images are supported, plus an optional alpha channel for transparency.
Sample depths range from 1 to 16 bits. PURL:
A PURL is a Persistent Uniform Resource Locator. Functionally, a PURL is a
URL. However, instead of pointing directly to the location of an Internet
resource, a PURL points to an intermediate resolution service. The PURL resolution
service associates the PURL with the actual URL and returns that URL to the client.
The client can then complete the URL transaction in the normal fashion. In
Web parlance, this is a standard HTTP redirect.
RTSP:
The Realtime Transport Protocol (RTP) is both an IETF Proposed Standard (RFC
1889) and an International Telecommuncations Union (ITU) Standard (H.225.0).
It is a packet format for multimedia data streams. RTP is used by both RTSP and
H.323 for the data portion of these protocols.
PCI:
Peripheral Component Interconnect (PCI) Local Bus. Currently by far the most
popular local I/O bus, the Peripheral Component Interconnect (PCI) bus was
developed by Intel and introduced in 1993. It is geared specifically to fifth-
and sixth-generation systems, although the latest generation 486 motherboards
use PCI as well.
PDF:
Adobe Portable Document Format (PDF) is the open de facto standard for electronic
document distribution worldwide. Adobe PDF is a universal file format that
preserves all the fonts, formatting, graphics, and color of any source document,
regardless of the application and platform used to create it. Adobe PDF files
are compact and can be shared, viewed, navigated, and printed exactly as intended
by anyone with free Adobe Acrobat Reader software.
PGP:
Pretty Good Privacy. A freeware program developed by Philip Zimmermann that
allows a user to send e-mail messages to anyone in the world, in complete
privacy. In addition you can send authentication with your messages so that
the recipient can verify that the message really came from you. You can encrypt
sensitive files on your computer so that the files remain private even if your
computer and disks are stolen.
PING:
Packet INnternet Groper. An Internet program used to determine whether a specific
IP address is accessible. It works by sending a packet to the specified address
and waiting for a reply. PING is used primarily to troubleshoot Internet connections.
In addition, PING reports how many hops are required to connect two Internet
hosts. There are many freeware and shareware PING utilities available for
personal computers.
POP:
Post Office Protocol. Basically, POP3 is intended to permit a workstation
(client) to dynamically access a mailbox on a server and download mail messages.
It's among the most simplistic Internet protocols around.
PPP:
Point-to-Point Protocol. Communication protocol used over serial lines to
support Internet connectivity.
RAM:
One of the most important components in a computer is the memory. Every time
a computer is started up, programs are loaded into memory. The memory into
where these programs are loaded is called RAM. RAM is an acronym for Random
Access Memory. It is from the RAM that most programs perform their functions
and operate to give the user the required results. Most RAM memory is housed
in chips or integrated circuits (ICs) that are either soldered or mounted
onto the motherboard of the computer.
RFC:
Request For Comments. The name of the result and the process for creating
a standard on the Internet. New standards are proposed and published on line,
as a "Request For Comments". The Internet Engineering Task Force is a consensus-building
body that facilitates discussion, and eventually a new standard is established,
but the reference number/name for the standard retains the acronym "RFC",
e.g. the official standard for e-mail is RFC 822.
RIPE
NCC: Short for the Réseaux IP Européens Network Coordination Centre. RIPE
NCC is one of three regional Internet registries that supply and administer
IP addresses. Founded in 1989, RIPE NCC is a non-profit organization run by volunteers.
RIPE NCC provides IP numbers to Europe, the Middle East and parts of Africa
and Asia.
RGB:
Red, Green, Blue. The three colors that create all other colors on a computer
screen.
S/MIME:
S/MIME (Secure/Multipurpose Internet Mail Extensions), described in [SMIME-MSG],
provides a method to send and receive secure MIME messages. In order to validate
the keys of a message sent to it, an S/MIME agent needs to certify that the
key is valid.
S-HTTP:
An extension to the HTTP protocol to support sending data securely over the
World Wide Web. Not all Web browsers and servers support S-HTTP. Another technology
for transmitting secure communications over the World Wide Web -- Secure Sockets
Layer (SSL) -- is more prevalent. However, SSL and S-HTTP have very different
designs and goals so it is possible to use the two protocols together. Whereas
SSL is designed to establish a secure connection between two computers, S-HTTP
is designed to send individual messages securely.
SDK:
Software Developer's Kit. Specific software "tools" and specifications provided
by a software's manufacturer. This "kit" enables computer application developers
to create their own programs or "plugins" that will work with or as an add
on enhancement of a certtain piece of software. SDRAM:
Synchronous DRAM. A new type of DRAM that can run at much higher clock speeds
than conventional memory. SDRAM actually synchronizes itself with the CPU's
bus and is capable of running at 100 MHz, about three times faster than conventional
FPM RAM, and about twice as fast EDO DRAM and BEDO DRAM. SDRAM is replacing
EDO DRAM in many newer computers.
SGI:
Silicon Graphics Incorporated . A company based in Mountain View, California
that provides computer hardware and software. SGI was founded by Dr. James
Clark in 1982 and had its initial public offering in 1986. It is best known
for products used to develop computer graphics such as those used to create special
effects and animation in motion pictures.
SGML:
Standard Generalized Markup Language .SGML is an international standard for
the publication and delivery of electronic information.
SIG:
Special Interest Group. People with a common interest who meet or exchange e-mail
messages on a particular topic in an organized way. Not to be confused with
a signature file or .sigfile.
SLIP:
Serial Line Internet Protocol. Communication protocol used over serial lines to
support Internet connectivity.
SMDS:
Switched Multimegabit Data Service (SMDS) is a high-speed, packet-switched,
datagram-based WAN networking technology used for communication over public
data networks (PDNs). SMDS can use fiber- or copper-based media and supports
speeds of 1.544 Mbps over Digital Signal level 1 (DS-1) transmission facilities,
or 44.736 Mbps over Digital Signal level 3 (DS-3) transmission facilities.
SMTP:
The objective of Simple Mail Transfer Protocol (SMTP) is to transfer mail
reliably and efficiently.
SQL:
Structured Query Language (SQL) was created to shield the database programmer
from understanding the specifics of how data is physically stored in each
database management system and also to provide a universal foundation for
updating, creating and extracting data from database systems that support
an SQL interface.
SSI:
SSI (Server Side Includes) are directives that are placed in HTML pages, and
evaluated on the server while the pages are being served. They let you add dynamically
generated content to an existing HTML page, without having to serve the entire
page via a CGI program, or other dynamic technology.
SSL:
The Secure Sockets Layer (SSL) security protocol provides data encryption,
server authentication, message integrity, and optional client authentication.
Because SSL is built into all major browsers and web servers, simply installing
a digital certificate turns on their SSL capabilities. Digital certificates
encrypt data using SSL technology, the industry-standard method for protecting
web communications.
T-1:
A leased-line connection capable of carrying data at 1,544,000 bits-per-second.
At maximum theoretical capacity, a T-1 line could move a megabyte in less
than 10 seconds. That is still not fast enough for full-screen, full-motion
video, for which you need at least 10,000,000 bits-per-second. T-1 is the
fastest speed commonly used to connect networks to the Internet.
T-3:
A leased-line connection capable of carrying data at 44,736,000 bits-per-second.
This is more than enough to do full-screen, full-motion video.
TCP/IP:
Transmission Control Protocol/Internet Protocol. A very popular data communications
protocol, since it is available for most operating systems and hardware platforms--so
these computers (UNIX workstations; PCs running MS-DOS, Windows, or OS/2;
Apple Macintoshes, IBM Mainframes; DEC Minicomputers; etc.) can all communicate.
TWAIN:
Technology (or Toolkit) Without an Interesting Name. The de facto interface
standard for scanners. Nearly all scanners come with a TWAIN driver, which
makes them compatible with any TWAIN-supporting software. Unfortunately, not
all scanner software is TWAIN-compatible.
UCE:
Unsolicited Commercial E-mail. Commonly referred to as spam.
UDP:
(User Datagram Protocol) -- One of the protocols for data transfer that is part
of the TCP/IP suite of protocols. UDP is a stateless protocol in that UDP makes
no provision for acknowledgement of packets received.
URI:
Short for Uniform Resource Identifier, the generic term for all types of names
and addresses that refer to objects on the World Wide Web. A URL is one kind
of URI.
UNIX:
A computer operating system (the basic software running on a computer, underneath
things like word processors and spreadsheets). UNIX is designed to be used
by many people at the same time (it is multi-user) and has TCP/IP built-in.
It is the most common operating system for servers on the Internet.
URL:
(Uniform Resource Locator) -- The standard way to give the address of any
resource on the Internet that is part of the World Wide Web (WWW). A URL looks
like this:
UUNET:
(UNIX to UNIX Network) The first commercial Internet service provider, headquartered
in Fairfax, VA. The company (www.us.uu.net) was founded in 1987 by Rick Adams,
one of the original developers of ARPAnet, the precursor to the Internet.
In 1996, UUNET merged with MFS Communications, Inc., and later that year,
WorldCom acquired both MFS and UUNET. In 1998, WorldCom acquired Advanced
Network Services and CompuServe Network Services. UUNET is now a full-service
provider.
USENET:
A world-wide system of discussion groups, with comments passed among hundreds
of thousands of machines. Not all USENET machines are on the Internet, maybe
half. USENET is completely decentralized, with over 10,000 discussion areas,
called newsgroups.
UUENCODE:
(Unix to Unix Encoding) -- A method for converting files from Binary to ASCII
(text) so that they can be sent across the Internet via e-mail.
VPN:
(Virtual Private Network) -- Usually refers to a network in which some of
the parts are connected using the public Internet, but the data sent across
the Internet is encrypted, so the entire network is "virtually" private.
VERONICA:
(Very Easy Rodent Oriented Net-wide Index to Computerized Archives) -- Developed
at the University of Nevada, Veronica is a constantly updated database of
the names of almost every menu item on thousands of gopher servers. The Veronica
database can be searched from most major
gopher menus.
WAIS:
((Wide Area Information Servers) -- A commercial software package that allows
the indexing of huge quantities of information, and thenmaking those indices
searchable across networks such as the Internet. A prominent feature of WAIS
is that the search results are ranked(scored) according to how relevant the
hits are, and that subsequent searches can find more stuff like that last
batch and thus refine the search process.
WAN:
(Wide Area Network) -- Any internet or network that covers an area larger
than a single building or campus.
WWW:
(World Wide Web) -- Frequently used (incorrectly) when referring to "The Internet",
WWW has two major meanings - First, loosely used: the whole constellation
of resources that can be accessed using Gopher, FTP, HTTP, telnet, USENET,
WAIS and some other tools. Second, the universe of hypertext servers (HTTP
servers) which are the servers that allow text, graphics, sound files, etc.
to be mixed together. W3C:
Short for World Wide Web Consortium, an international consortium of companies
involved with the Internet and the Web. The W3C was founded in 1994 by Tim
Berners-Lee, the original architect of the World Wide Web. The organization's
purpose is to develop open standards so that the Web evolves in a single direction
rather than being splintered among competing factions. The W3C is the chief
standards body for HTTP and HTML
XML:
XML is the Extensible Markup Language. It is designed to improve the functionality
of the Web by providing more flexible and adaptable information identification.It
is called extensible because it is not a fixed format like HTML (a single,
predefined markup language). Instead, XML is actually a `metalanguage' --
a language for describing other languages -- which lets you design your own
customized markup languages for limitless different types of documents. XML
can do this because it's written in SGML, the international standard metalanguage
for text markup systems (ISO 8879). |
