-
- 10BaseT
- 10 Megabit per second base-band
Ethernet specification using two pairs of
twisted-pair cabling (Category 3, 4 or 5): one
pair for transmitting data and the other for
receiving data. 10BaseT has a distance limit of
approximately 100 meters per segment.
- 100BaseT
- 100 Megabit per second base-band
Fast Ethernet specification using UTP wiring. Like
the 10BaseT technology on which it is based,
100BaseT sends link pulses over the network
segment when no traffic is present. However, these
link pulses contain more information than those
used in 10BaseT.
- A Record
- An A record is part of the zone
file. It is used to point Internet traffic to an
IP address. For example, you can use an "A
record" to designate abc.yourdomain.com to
send traffic to your web site at IP address
209.15.32.135. You can also designate
xyz.yourdomain.com to go to a separate IP address.
- Access
[Microsoft®]
- MS Access® published by
Microsoft is an easy to use and highly integrated
database creation and maintenance software.
Capable of online databases, the software is
supported with the NT® hosting platform.
- ADSL
- (Asymmetric Digital Subscriber
Line) -- A method for moving data over regular
phone lines. An ADSL circuit is much faster than a
regular phone connection, and the wires coming
into the subscriber's premises are the same
(copper) wires used for regular phone service. An
ADSL circuit must be configured to connect two
specific locations, similar to a leased line.
A commonly discussed
configuration of ADSL would allow a subscriber to
receive data (download) at speeds of up to 1.544
Megabits per second, and to send (upload) data at
speeds of 128 kilobits per second. Thus the
'Asymmetric' part of the acronym.
Another commonly discussed
configuration would be symmetrical: 384 kilobits
per second in both directions. In theory ADSL
allows download speeds of up to 9 megabits per
second and upload speeds of up to 640 kilobits per
second.
ADSL is often discussed as an
alternative to ISDN, allowing higher speeds
in cases where the connection is always to the
same place.
- Anonymous
FTP
- Anonymous File Transfer Protocol
allows the public to log into an FTP server with a
common login (usually "ftp" or
"anonymous" and any password (usually
the person's e-mail address is used as the
password). Anonymous FTP is beneficial for the
distribution of large files to the public,
avoiding the need to assign large numbers of login
and password combinations for FTP access.
- Applet
- A small Java program that
can be embedded in an HTML page. Applets
differ from full-fledged Java applications in that
they are not allowed to access certain resources
on the local computer, such as files and serial
devices (modems, printers, etc.), and are
prohibited from communicating with most other
computers across a network. The current rule is
that an applet can only make an Internet
connection to the computer from which the applet
was sent.
- Archie
- A tool (software) for finding
files stored on anonymous FTP sites. You
need to know the exact file name or a sub-string
of it.
- ARPANet
- (Advanced Research Projects
Agency Network) -- The precursor to the Internet.
Landmark packet-switching network established in
1969 by the US Department of Defense as an
experiment in wide-area-networking that would
survive a nuclear war.
- ASP
- ASP - Active Server Pages (ASP).
ASP files, which provide Web developers with an
easier, faster, and more powerful way to build Web
applications, are regular HTML pages with embedded
scripts. These scripts can be written in any
language and processed by the server when the
file's URL is requested.
Source: http://www.microsoft.com/ntserver/nts/exec/overview/changed.asp
- ATM
- ATM -- Asynchronous Transfer
Mode. International standard for cell relay in
which multiple service types (such as voice,
video, or data) are conveyed in fixed-length
(53-byte) cells. Fixed-length cells allow cell
processing to occur in hardware, thereby reducing
transit delays. ATM is designed to take advantage
of high-speed transmission media such as E3, SONET,
and T3.
- ASCII
- (American Standard Code for
Information Interchange) -- This is the de facto
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, plus parity.
- Backbone
- A high-speed line or series of
connections that forms a major pathway within a
network. The term is relative, as a backbone in a
small network will likely be much smaller
than many non-backbone lines in a large network.
- Bandwidth
- The difference between the
highest and lowest frequencies available for
network signals. The term is also used to describe
the rated throughput capacity of a given network
medium or protocol. In short, bandwidth is a loose
term used to describe the throughput capacity
(measured in Kilobits or Megabits per second) of a
specific circuit.
- Baud
- Unit of signaling speed equal to
the number of discrete signal elements transmitted
per second. Baud is synonymous with bits per
second (bps). In common usage the baud rate of a modem
is how many bits it can send or receive per
second. Technically, baud is the number of times
per second that the carrier signal shifts value -
for example a 1200 bit-per-second modem actually
runs at 300 baud, but it moves 4 bits per baud (4
x 300 = 1200 bits per second).
- 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.
- Binhex
- (BINary HEXadecimal) -- A method
for converting non-text files (non-ASCII) into ASCII.
This is needed because Internet e-mail can only
handle ASCII.
- Bit
- (Binary DigIT) -- A single digit
number in base-2, in other words, either a 1 or a
zero. The smallest unit of computerized data. Bandwidth
is usually measured in bits-per-second.
- BITNET
- (Because It's Time NETwork (or
Because It's There NETwork)) -- A network
of educational sites separate from the Internet,
but e-mail is freely exchanged between BITNET
and the Internet. Listservs, the most
popular form of e-mail discussion groups,
originated on BITNET. BITNET machines are usually
mainframes running the VMS operating system, and
the network is probably the only international
network that is shrinking.
- 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.
- Browser
- Client software that is used to
look at various kinds of Internet resources.
Examples include Microsoft's Internet Explorer and
Netscape's Navigator.
- 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. See Also: Bit
- Certificate
Authority
- An issuer of Security
Certificates used in SSL connections.
- CGI
- (Common Gateway Interface) -- A
set of rules that describe how a Web Server
communicates with another piece of software on the
same machine, and how the other piece of software
(the 'CGI program') talks to the web server. Any
piece of software can be a CGI program if it
handles input and output according to the CGI
standard.
Usually a CGI program is a small
program that takes data from a web server and does
something with it, like putting the content of a
form into an e-mail message, or turning the data
into a database query.
CGI "scripts" are just
scripts which use CGI. CGI is often confused with
Perl, which is a programming language, while CGI
is an interface to the server from a particular
program. Perl is an application of CGI, as well as
MIVA, Python, PHP3, and other scripting languages.
- cgi-bin
- The most common name of a
directory on a web server in which CGI
programs are stored. The 'bin' part of 'cgi-bin'
is a shorthand version of 'binary', because once
upon a time, most programs were referred to as
'binaries'. In real life, most programs found in
cgi-bin directories are text files -- scripts that
are executed by binaries located elsewhere on the
server. While most programs using CGI are stored
in this directory, it is not a requirement for
using CGI.
- Client
- A software program that is used
to contact and obtain data from a server software
program on another computer, often across a great
distance. Each client program is designed to work
with one or more specific kinds of server
programs, and each server requires a specific kind
of client. A web browser and an FTP program are
specific kinds of clients. See
Also: Browser, Server
- Co-Location
- Network Operations Centers such
as Apexisp.net's offer the opportunity for
customers to place their web servers and other
network equipment in their NOC which are connected
via high speed fiber data lines to the backbone of
the Internet. Administration is done remotely so
that a customer far away can configure and control
their network equipment.
- Cold
Fusion
- Cold Fusion is a scripting
language for web designers that want wish to do
advanced development and/or database interfacing.
Cold Fusion supports MS Access, dBASE, FoxPro, and
Paradox databases.
- Contact
Record
- In the case of many registries,
contact information for technical, billing and
administrative purposes are maintained in their
database. It is important to keep your contact
records updated to ensure that billing and renewal
can proceed without problems.
- Cookie
- The most common meaning of
'Cookie' on the Internet refers to a piece of
information sent by a Web Server to a Web Browser
that the Browser software is expected to save and
to send back to the Server whenever the browser
makes additional requests from the Server.
Depending on the type of Cookie
used, and the Browser's settings, the Browser may
accept or not accept the Cookie, and may save the
Cookie for either a short time or a long time.
Cookies might contain
information such as login or registration
information, online 'shopping cart' information,
user preferences, etc.
When a Server receives a request
from a Browser that includes a Cookie, the Server
is able to use the information stored in the
Cookie. For example, the Server might customize
what is sent back to the user, or keep a log of
particular user's requests.
Cookies are usually set to
expire after a predetermined amount of time and
are usually saved in memory until the Browser
software is closed down, at which time they may be
saved to disk if their 'expire time' has not been
reached.
Cookies do not
read your hard drive and send your life story to
the CIA, but they can be used to gather more
information about a user than would be possible
without them.
- Cyberpunk
- Cyberpunk was originally a
cultural sub-genre of science fiction taking place
in a not-so-distant, dystopian,
over-industrialized society. The term grew out of
the work of William Gibson and Bruce Sterling and
has evolved into a cultural label encompassing
many different kinds of human, machine, and punk
attitudes. It includes clothing and lifestyle
choices as well.
- Cyberspace
- Term originated by author William
Gibson in his novel Neuromancer the word
Cyberspace is currently used to describe the whole
range of information resources available through
computer networks.
- DNS: Domain
Naming System
- The DNS is a distributed,
replicated that allows name-servers to map easily
remembered domain names to an IP number.
- Dedicated
Server
- For those customers that want the
advantages of co-location without the hassles of
purchasing their own server. See co-location.
- Digerati
- The digital version of literati,
it is a reference to a vague cloud of people seen
to be knowledgeable, hip, or otherwise in-the-know
in regards to the digital revolution.
- Domain
Name
- The unique name that identifies
an Internet site. Domain Names always have 2 or
more parts, separated by dots. The part on the
left is the most specific, and the part on the
right is the most general. A given machine may
have more than one Domain Name but a given Domain
Name points to only one machine. For example, the
domain names: Apexisp.net, ftp.apexisp.net,
whatever.apexisp.net can all refer to the same
machine, but each domain name can refer to no more
than one machine.
Usually, all of the machines on
a given Network will have the same thing as the
right-hand portion of their Domain Names in the
examples above. It is also possible for a Domain
Name to exist but not be connected to an actual
machine. This is often done so that a group or
business can have an Internet e-mail address
without having to establish a real Internet site.
In these cases, some real Internet machine must
handle the mail on behalf of the listed Domain
Name.
- E-Commerce
- Electronic Commerce. Refers to
the general exchange of goods and services via the
Internet.
- E-mail
- (Electronic Mail) -- Messages,
usually text, sent from one person to another via
computer. E-mail can also be sent automatically to
a large number of addresses (Mailing List).
- Ethernet
- A very common method of
networking computers in a LAN. Ethernet
will handle about 10,000,000 bits-per-second and
can be used with almost any kind of computer.
- FAQ
- (Frequently Asked Questions) --
FAQs are documents that list and answer the most
common questions on a particular subject. There
are hundreds of FAQs on subjects as diverse as Pet
Grooming and Cryptography. FAQs are usually
written by people who have tired of answering the
same question over and over.
- FDDI
- (Fiber Distributed Data
Interface) -- A standard for transmitting data on
optical fiber cables at a rate of around
100,000,000 bits-per-second (10 times as fast as Ethernet,
about twice as fast as T-3). See Also:
Bandwidth, Ethernet, T-1 , T-3
- Finger
- An Internet software tool for
locating people on other Internet sites. Finger is
also sometimes used to give access to non-personal
information, but the most common use is to see if
a person has an account at a particular Internet
site. Many sites do not allow incoming Finger
requests, but many do.
- Fire
Wall
- A combination of hardware and
software that separates a LAN into two or
more parts for security purposes.
- Flame
- Originally, flame meant to carry
forth in a passionate manner in the spirit of
honorable debate. Flames most often involved the
use of flowery language and flaming well was an
art form. More recently flame has come to refer to
any kind of derogatory comment no matter how
witless or crude.
- Flame
War
- When an online discussion
degenerates into a series of personal attacks
against the debaters, rather than discussion of
their positions. A heated exchange.
- FrontPage
- Microsoft® FrontPage® is a site
creation and management software tool. One of the
most popular website creation software packages
the software, both FrontPage® 98 and FrontPage ®2000
is widely supported by the hosting community.
- FTP
- (File Transfer Protocol) -- A
very common method of moving files between two
Internet sites. FTP is a special way to login
to another Internet site for the purposes of
retrieving and/or sending files. There are many
Internet sites that have established publicly
accessible repositories of material that can be
obtained using FTP, by logging in using the
account name anonymous, thus these sites are
called anonymous FTP servers.
- Gateway
- The technical meaning is a
hardware or software set-up that translates
between two dissimilar protocols, for example
Prodigy has a gateway that translates between its
internal, proprietary e-mail format and Internet
e-mail format. Another, sloppier meaning of
gateway is to describe any mechanism for providing
access to another system, e.g. AOL might be called
a gateway to the Internet.
- Gigabyte
- 1024 Megabytes
- Gopher
- A widely successful method of
making menus of material available over the
Internet. Gopher is a Client and Server
style program, which requires that the user have a
Gopher Client program. Although Gopher
spread rapidly across the globe in only a couple
of years, it has been largely supplanted by
Hypertext, also known as WWW (World Wide Web).
There are still thousands of Gopher Servers
on the Internet and we can expect they will remain
for a while.
- hit
- As used in reference to the World
Wide Web, 'hit' means a single request from a web browser
for a single item from a web server; thus
in order for a web browser to display a page that
contains 3 graphics, 4 'hits' would occur at the
server: 1 for the HTML page, and one for
each of the 3 graphics.
'hits' are often used as a very
rough measure of load on a server, e.g. 'Our
server has been getting 300,000 hits per month.'
Because each 'hit' can represent anything from a
request for a tiny document (or even a request for
a missing document) all the way to a request that
requires some significant extra processing (such
as a complex search request), the actual load on a
machine from 1 hit is almost impossible to define.
- Home
Page (or Homepage)
- Several meanings. Originally, the
web page that your browser is set to
use when it starts up. The more common meaning
refers to the main web page for a business,
organization, person or simply the main page out
of a collection of web pages, e.g. 'Check out
so-and-so's new Home Page.'
Another sloppier use of the term
refers to practically any web page as a
'homepage,' e.g. 'That web site has 65 homepages
and none of them are interesting.'
- Host
- Any computer on a network
that is a repository for services available to
other computers on the network. It is quite
common to have one host machine provide several
services, such as WWW and USENET.
- Hosting
- This term can be used to refer to
the housing of a web site, email or a domain. See
Email hosting and Web Site hosting for more
details.
- HTML
- (Hypertext Markup Language) --
The coding language used to create Hypertext
documents for use on the World Wide Web.
HTML looks a lot like old-fashioned typesetting
code, where you surround a block of text with
codes that indicate how it should appear,
additionally, in HTML you can specify that a block
of text, or a word, is linked to another file on
the Internet. HTML files are meant to be viewed
using a World Wide Web Client Program, such
as Netscape or Mosaic.
- HTTP
- (Hypertext Transport Protocol) --
The protocol for moving hypertext files
across the Internet. Requires a HTTP client
program on one end, and an HTTP server
program on the other end. HTTP is the most
important protocol used in the World Wide Web
(WWW).
- Hypertext
- Generally, any text that contains
links to other documents - words or phrases in the
document that can be chosen by a reader and which
cause another document to be retrieved and
displayed.
- IMHO
- (In My Humble Opinion) -- A
shorthand appended to a comment written in an
online forum, IMHO indicates that the writer is
aware that they are expressing a debatable view,
probably on a subject already under discussion.
One of may such short-hand's in common use online,
especially in discussion forums.
- Index
Server
- Index Server indexes the contents
and properties of documents on an Internet or
intranet Web site served by IIS 4.0. Index Server
enables Web clients with any browser to search a
Web site by filling in the fields of an HTML query
form.

- Internet
- (Upper case I) The vast
collection of inter-connected networks that all
use the TCP/IP protocols and that evolved from the
ARPANET of the late 60's and early 70's.
The Internet now (July 1995) connects roughly
60,000 independent networks into a vast global internet.
- internet
- (Lower case i) Any time
you connect 2 or more networks together,
you have an internet - as in inter-national or
inter-state.
- InterNIC
- InterNIC (now known as Network
Solutions) currently holds an exclusive contract
with the U.S. government to assign domain names
for .COM, .NET and .ORG. The contract is scheduled
to expire September 30, 1998. Network Solutions is
the company that runs the InterNIC registry.
- Intranet
- A private network inside a
company or organization that uses the same kinds
of software that you would find on the public Internet,
but that is only for internal use.
As the Internet has become more
popular many of the tools used on the Internet are
being used in private networks, for example, many
companies have web servers that are available only
to employees.
Note that an Intranet may not
actually be an internet -- it may simply be a
network.
- IP
Number
- (Internet Protocol Number) --
Sometimes called a dotted quad. A unique number
consisting of 4 parts separated by dots,
e.g.165.113.245.2
Every machine that is on the
Internet has a unique IP number - if a machine
does not have an IP number, it is not really on
the Internet. Most machines also have one or more Domain
Names that are easier for people to remember.
- IRC
- (Internet Relay Chat) --
Basically a huge multi-user live chat facility.
There are a number of major IRC servers
around the world which are linked to each other.
Anyone can create a channel and anything that
anyone types in a given channel is seen by all
others in the channel. Private channels can (and
are) created for multi-person conference calls.
- ISDN
- (Integrated Services Digital
Network) -- Basically a way to move more data over
existing regular phone lines. ISDN is rapidly
becoming available to much of the USA and in most
markets it is priced very comparably to standard
analog phone circuits. It can provide speeds of
roughly 128,000 bits-per-second over regular phone
lines. In practice, most people will be limited to
56,000 or 64,000 bits-per-second.
- ISP
- (Internet Service Provider) -- An
institution that provides access to the Internet
in some form, usually for money.
- Java
- Java is a network-oriented
programming language invented by Sun Microsystems
that is specifically designed for writing programs
that can be safely downloaded to your computer
through the Internet and immediately run without
fear of viruses or other harm to your computer or
files. Using small Java programs (called "Applets"),
Web pages can include functions such as
animations, calculators, and other fancy tricks.
We can expect to see a huge
variety of features added to the Web using Java,
since you can write a Java program to do almost
anything a regular computer program can do, and
then include that Java program in a Web page.
- JDK
- (Java Development Kit) -- A
software development package from Sun Microsystems
that implements the basic set of tools needed to
write, test and debug Java applications and
applets
- Kilobyte
- A thousand bytes. Actually,
usually 1024 (210) bytes.
- LAN
- (Local Area Network) -- A
computer network limited to the immediate area,
usually the same building or floor of a building.
- Leased-line
- Refers to a phone line that is
rented for exclusive 24-hour, 7 -days-a-week use
from your location to another location. The
highest speed data connections require a leased
line.
- Listserv
- The most common kind of maillist,
Listservs originated on BITNET but they are
now common on the Internet.
- Local
Registry Fees
- Most TLDs require initial
registration fees as well as annual or bi-annual
renewal fees. Prices vary from cost-free to
thousands of dollars per domain depending on the
TLD chosen. For example, .COM domains cost which
covers the first two years. Renewal fees for .COM
are annually after the first two years expire.
- Login
- Noun or a verb. Noun: The account
name used to gain access to a computer system. Not
a secret (contrast with Password). Verb:
The act of entering into a computer system, e.g. Login
to the WELL and then go to the GBN conference.
- Maillist
- (or Mailing List) A
(usually automated) system that allows people to
send e-mail to one address, whereupon their
message is copied and sent to all of the other
subscribers to the maillist. In this way, people
who have many different kinds of e-mail access can
participate in discussions together.
- Megabyte
- A million bytes. A
thousand kilobytes.
- MIDI
- Musical Instrument Digital
Interface -- A network and accompanying protocol
developed in the 1970's for tranmitting various
information between musical and other devices
including keyboards, samplers, lights,
controllers, etc.
- MIME
- (Multipurpose Internet Mail
Extensions) -- The standard for attaching non-text
files to standard Internet mail messages. Non-text
files include graphics, spreadsheets, formatted
word-processor documents, sound files, etc.
An email program is said to be
MIME Compliant if it can both send and receive
files using the MIME standard.
When non-text files are sent
using the MIME standard they are converted
(encoded) into text - although the resulting text
is not really readable.
Generally speaking the MIME
standard is a way of specifying both the type of
file being sent (e.g. a QuicktimeÅ video file),
and the method that should be used to turn it back
into its original form.
Besides email software, the MIME
standard is also universally used by Web Servers
to identify the files they are sending to Web Clients,
in this way new file formats can be accommodated
simply by updating the Browsers' list of pairs of
MIME-Types and appropriate software for handling
each type.
- Mirror
- Generally speaking, 'to mirror'
is to maintain an exact copy of something.
Probably the most common use of the term on the
Internet refers to 'mirror sites' which are web
sites, or FTP sites that maintain exact
copies of material originated at another location,
usually in order to provide more widespread access
to the resource.
Another common use of the term
'mirror' refers to an arrangement where
information is written to more than one hard disk
simultaneously, so that if one disk fails, the
computer keeps on working without losing anything.
- Modem
- (MOdulator, DEModulator) -- A
device that you connect to your computer and to a
phone line, that allows the computer to talk to
other computers through the phone system.
Basically, modems do for computers what a
telephone does for humans.
- Modify
(Domain Name)
- The database that the TLD
registries maintain need to be accurate in order
for name resolution, billing, renewal notices and
public records to be processed correctly.
Typically modifications are required when
name-servers need to change or the contacts change
email or postal address or phone number. The
procedures for modifying records will depend on
the registry.
- MOO
- (Mud, Object Oriented) -- One of
several kinds of multi-user role-playing
environments, so far only text-based.
- Mosaic
- The first WWW browser that
was available for the Macintosh, Windows, and UNIX
all with the same interface. Mosaic really started
the popularity of the Web. The source-code to
Mosaic has been licensed by several companies and
there are several other pieces of software as good
or better than Mosaic, most notably, Netscape.
- MUD
- (Multi-User Dungeon or Dimension)
-- A (usually text-based) multi-user simulation
environment. Some are purely for fun and flirting,
others are used for serious software development,
or education purposes and all that lies in
between. A significant feature of most MUDs is
that users can create things that stay after they
leave and which other users can interact with in
their absence, thus allowing a world to be built
gradually and collectively.
- MUSE
- (Multi-User Simulated
Environment) -- One kind of MUD - usually with
little or no violence.
- MX
Record: Mail Exchange
- Mail Exchange record is part of
the zone file and is used to designate which mail
server machine should process email for a specific
domain.
- NT
- Windows NT® is 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. Used by web hosting companies in the network
environment to offer customers support for
Microsoft base products such as MS Access®, MS
SQL® 7.0, and FrontPage® 2000.
- Name
Servers
- A computer that performs the
mapping of easily remembered domain names to IP
addresses. Sometimes referred to as a host server.
- Netiquette
- The etiquette on the Internet.
See Also: Internet
- Netizen
- Derived from the term citizen,
referring to a citizen of the Internet, or
someone who uses networked resources. The term
connotes civic responsibility and participation.
See Also: Internet
- Netscape®
- A WWW Browser and the name
of a company. The Netscape (tm) browser was
originally based on the Mosaic program
developed at the National Center for
Supercomputing Applications (NCSA).
Netscape has grown in features
rapidly and is widely recognized as the best and
most popular web browser. Netscape corporation
also produces web server software.
Netscape provided major
improvements in speed and interface over other
browsers, and has also engendered debate by
creating new elements for the HTML language
used by Web pages -- but the Netscape extensions
to HTML are not universally supported.
The main author of Netscape,
Mark Andreessen, was hired away from the NCSA by
Jim Clark, and they founded a company called
Mosaic Communications and soon changed the name to
Netscape Communications Corporation.
- Network
- Any time you connect 2 or more
computers together so that they can share
resources, you have a computer network. Connect 2
or more networks together and you have an internet.
- Newsgroup
- The name for discussion groups on
USENET. See Also: USENET
- NIC
- (Networked Information Center) --
Generally, any office that handles information for
a network. The most famous of these on the
Internet is Network Solutions, which is where new
domain names are registered. Another definition:
NIC also refers to Network Interface Card which
plugs into a computer and adapts the network
interface to the appropriate standard. ISA, PCI,
and PCMCIA cards are all examples of NICs.
- NNTP
- (Network News Transport Protocol)
-- The protocol used by client and server
software to carry USENET postings back and
forth over a TCP/IP network. If you
are using any of the more common software such as Netscape,
Nuntius, Internet Explorer, etc. to participate in
newsgroups then you are benefiting from an
NNTP connection.
- Node
- Any single computer connected to
a network.
- OC-3
- Refers to a circuit that
transmits 155,000,000 bits per second. This is the
size of the largest Internet backbone providers
networks.
- Packet
Switching
- The method used to move data
around on the Internet. In packet
switching, all the data coming out of a machine is
broken up into chunks, each chunk has the address
of where it came from and where it is going. This
enables chunks of data from many different sources
to co-mingle on the same lines, and be sorted and
directed to different routes by special machines
along the way. This way many people can use the
same lines at the same time.
- Parking
(Domain Name)
- Registries require the use of
name servers or hosts for every domain registered.
Parking is the process by which someone selects a
domain name, and "parks" it by
registering the domain name under someone's name
servers. Parking can be done by anyone, to anyone
else who has active name servers. However, parking
a domain name alone will result in no service (web
hosting, e-mail) for that particular domain name.
- Password
- A code used to gain access to a
locked system. Good passwords contain letters and
non-letters and are not simple combinations such
as virtue7. A good password might be: Hot-6
- Plug-in
- A (usually small) piece of
software that adds features to a larger piece of
software. Common examples are plug-ins for the
Netscape® browser and web server.
Adobe Photoshop® also uses plug-ins.
The idea behind plug-in's is
that a small piece of software is loaded into
memory by the larger program, adding a new
feature, and that users need only install the few
plug-ins that they need, out of a much larger pool
of possibilities. Plug-ins are usually developed
by a third party.
- POP
- (Point of Presence, also Post
Office Protocol) -- Two commonly used meanings:
Point of Presence and Post Office Protocol. A
Point of Presence usually means a city or location
where a network can be connected to, often with
dial up phone lines. So if an Internet company
says they will soon have a POP in Belgrade, it
means that they will soon have a local phone
number in Belgrade and/or a place where leased
lines can connect to their network. A second
meaning, Post Office Protocol refers to the way
e-mail software such as Eudora gets mail from a
mail server. When you obtain a SLIP, PPP, or shell
account you almost always get a POP account with
it, and it is this POP account that you tell your
e-mail software to use to get your mail.
- Port
- 3 meanings. First and most
generally, a place where information goes into or
out of a computer, or both. E.g. the serial port
on a personal computer is where a modem
would be connected.
On the Internet port often
refers to a number that is part of a URL,
appearing after a colon (:) right after the domain
name. Every service on an Internet server
listens on a particular port number on that
server. Most services have standard port numbers,
e.g. Web servers normally listen on port 80.
Services can also listen on non-standard ports, in
which case the port number must be specified in a
URL when accessing the server, so you might see a
URL of the form:
gopher://peg.cwis.uci.edu:7000/
shows a gopher server running on
a non-standard port (the standard gopher port is
70). Finally, port also refers to translating a
piece of software to bring it from one type of
computer system to another, e.g. to translate a
Windows program so that is will run on a
Macintosh.
- Posting
- A single message entered into a
network communications system. E.g. A single
message posted to a newsgroup or message
board. See Also: Newsgroup
- PPP
- (Point to Point Protocol) -- Most
well known as a protocol that allows a computer to
use a regular telephone line and a modem to
make TCP/IP connections and thus be really
and truly on the Internet.
- Propagation
- The process whereby the
name-servers throughout the world have updated
their records for a specific domain. For example,
if you move your domain from one host to another,
it will take around 24 hours or so for the new
address to broadcast everywhere. During that 24
hour period, the traffic is decreasing at the old
location and increasing at the new location.
- PSTN
- (Public Switched Telephone
Network) -- The regular old-fashioned telephone
system.
- Real
Audio / Real Video
- Real Audio/Real Video enables
users of personal computers and other consumer
electronic devices to send and receive audio,
video and other multimedia services using the Web.
enable users of personal
computers and other consumer electronic devices to
send and receive audio, video and other multimedia
services using the Web.
- Register
(Domain Name)
- Since every domain is unique,
registries have been set up to assign domains to
individuals and organizations. When a domain is
registered with the appropriate registry, that
domain is assigned and becomes no longer available
for anyone else to use. Typically, there are
registration and renewal fees (local registry
fees) associated with the right to use a domain.
However, there are some TLDs that are provided at
no charge.
- Registrant
(Domain Name)
- The entity, organization or
individual that will be using the domain name.
- Registrar
(Domain Name)
- Some registries don't provide the
ability for end users to register domains with
them directly. They might require end users to
purchase the domain through an internet provider
that is acting as the registrar.
- Registry
(Domain Name)
- An organization responsible for
assigning domain names for the TLD that they
manage. Furthermore, it is their responsibility to
update the global DNS tables that all name-servers
use to resolve domain names. For example, InterNIC
is the registry for .COM, .NET and .ORG domain
names.
- Renewal
(Domain Name)
- Most TLDs need to be renewed at
some scheduled yearly interval. This is an
opportunity for both the registrant and the
registry to update their records as well as
collect any applicable renewal fees.
- Resolution
(Domain Name)
- The conversion of an internet
address or domain name into the corresponding
physical location.
- 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.
- Router
- A special-purpose computer (or
software package) that handles the connection
between 2 or more networks. Routers spend
all their time looking at the destination
addresses of the packets passing through
them and deciding which route to send them on.
- Security
Certificate
- A chunk of information (often
stored as a text file) that is used by the SSL
protocol to establish a secure connection.
Security Certificates contain
information about who it belongs to, who it was
issued by, a unique serial number or other unique
identification, valid dates, and an encrypted
'fingerprint' that can be used to verify the
contents of the certificate.
In order for an SSL connection
to be created both sides must have a valid
Security Certificate.
- Server
- A computer, or a software
package, that provides a specific kind of service
to client software running on other
computers. The term can refer to a particular
piece of software, such as a WWW server, or
to the machine on which the software is running,
e.g. Our mail server is down today, that's why
e-mail isn't getting out. A single server machine
could have several different server software
packages running on it, thus providing many
different servers to clients on the network.
- Shockwave
- Shockwave, produced by
Macromedia, allows you to view new forms of
entertainment on the Web, such as games, music,
rich-media chat, interactive product demos, and
e-merchandising applications
- SLIP
- (Serial Line Internet Protocol)
-- A standard for using a regular telephone line
(a serial line) and a modem to connect a
computer as a real Internet site. SLIP is
gradually being replaced by PPP.
- SMDS
- (Switched Multimegabit Data
Service) -- A new standard for very high-speed
data transfer.
- SMTP
- (Simple Mail Transport Protocol)
-- The main protocol used to send electronic mail
on the Internet.
SMTP consists of a set of rules
for how a program sending mail and a program
receiving mail should interact.
Almost all Internet email is
sent and received by clients and servers
using SMTP, thus if one wanted to set up an email
server on the Internet one would look for email
server software that supports SMTP.
- SNMP
- (Simple Network Management
Protocol) -- A set of standards for communication
with devices connected to a TCP/IP network.
Examples of these devices include routers,
hubs, and switches.
A device is said to be 'SNMP
compatible' if it can be monitored and/or
controlled using SNMP messages. SNMP messages are
known as 'PDU's' - Protocol Data Units.
Devices that are SNMP compatible
contain SNMP 'agent' software to receive, send,
and act upon SNMP messages.
Software for managing devices
via SNMP are available for every kind of commonly
used computer and are often bundled along with the
device they are designed to manage. Some SNMP
software is designed to handle a wide variety of
devices.
- Spam
(or Spamming)
- An inappropriate attempt to use a
mailing list, or USENET or other
networked communications facility as if it was a
broadcast medium (which it is not) by sending the
same message to a large number of people who
didn't ask for it. The term probably comes from a
famous Monty Python skit which featured the word
spam repeated over and over. The term may also
have come from someone's low opinion of the food
product with the same name, which is generally
perceived as a generic content-free waste of
resources. (Spam is a registered trademark of
Hormel Corporation, for its processed meat
product.)
E.g. Mary spammed 50 USENET
groups by posting the same message to each.
- SQL
- (Structured Query Language) -- A
specialized programming language for sending
queries to databases. Most industrial-strength and
many smaller database applications can be
addressed using SQL. Each specific application
will have its own version of SQL implementing
features unique to that application, but all
SQL-capable databases support a common subset of
SQL.
- SSL
- (Secure Sockets Layer) -- A
protocol designed by Netscape Communications to
enable encrypted, authenticated communications
across the Internet.
SSL used mostly (but not
exclusively) in communications between web browsers
and web servers. URL's that begin
with 'https' indicate that an SSL connection will
be used.
SSL provides 3 important things:
Privacy, Authentication, and Message Integrity.
In an SSL connection each side
of the connection must have a Security
Certificate, which each side's software sends
to the other. Each side then encrypts what it
sends using information from both its own and the
other side's Certificate, ensuring that only the
intended recipient can de-crypt it, and that the
other side can be sure the data came from the
place it claims to have come from, and that the
message has not been tampered with.
- Sysop
- (System Operator) -- Anyone
responsible for the physical operations of a
computer system or network resource. A System
Administrator decides how often backups and
maintenance should be performed and the System
Operator performs those tasks.
- 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) -- This is the suite
of protocols that defines the Internet.
Originally designed for the UNIX operating
system, TCP/IP software is now available for every
major kind of computer operating system. To be
truly on the Internet, your computer must
have TCP/IP software.
- Telnet
- The command and program used to login
from one Internet site to another. The
telnet command/program gets you to the login:
prompt of another host.
- Terabyte
- 1024 gigabytes.
- Terminal
- A device that allows you to send
commands to a computer somewhere else. At a
minimum, this usually means a keyboard and a
display screen and some simple circuitry. Usually
you will use terminal software in a personal
computer - the software pretends to be (emulates)
a physical terminal and allows you to type
commands to a computer somewhere else.
- Terminal
Server
- A special purpose computer that
has places to plug in many modems on one
side, and a connection to a LAN or host
machine on the other side. Thus the terminal
server does the work of answering the calls and
passes the connections on to the appropriate node.
Most terminal servers can provide PPP or SLIP
services if connected to the Internet.
- Top Level
Domain: (TLD)
- A Top Level Domain (TLD) is the
uppermost in the hierarchy of domain names. For
example, apexisp.net is our domain name. The
"com" is considered the TLD and the
"apexisp.net" is considered the second
level domain. Together they form a domain name
which is unique. There are two types of TLDs. The
most common type is the Generic or Global TLDs
which include .COM, .NET, .ORG, .MIL, .INT and
.EDU. There is a possibility that new gTLDs will
be introduced in the near future. National or
ccTLDs are two letter country code domains that
are managed by a registry designated and
controlled by each specific country. Each registry
might have differing prices, residency
requirements and structure.
- Trademark
- As it relates to domain names...
a word, phrase or slogan used to identify and
distinguish the source of the goods or services.
Trademark law may be different worldwide. If
someone registers a domain name such as
microsoft.to then Microsoft would need to go to
the courts in Tonga to fight to get the name back.
Expensive international litigation is one reason
why it is important to protect your trademarks
before someone else registers the names.
- Transfer
(Domain Name)
- On occasion, domains are sold to
another organization or sometimes the name of a
company might change. Most registries require a
letter of permission from the old owner to hand
over control to the new owner. The procedures for
Transfer of ownership will depend on the registry.
- TTFN
- (Ta Ta For Now) -- A shorthand
appended to a comment written in an online forum.
See Also: IMHO, BTW
- 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: http://webhosting.apexisp.net/glossary.html
or telnet://anywhere.you.want or
news:new.newusers.questions etc.
The most common way to use a URL
is to enter into a WWW browser program, such as
Netscape, or Lynx.
- 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. See
Also: Newsgroup
- 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.
- 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. See Also:
Gopher
- VB
Script
- The Microsoft® Visual Basic®
programming language, is a fast, portable,
lightweight interpreter for use in World Wide Web
browsers and other applications that use Microsoft®
ActiveX® Controls, Automation servers, and Java
applets Source: http://msdn.microsoft.com/scripting/default.htm
- WAIS
- (Wide Area Information Servers)
-- A commercial software package that allows the
indexing of huge quantities of information, and
then making 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.
- Web
- See: WWW
- Whois
- Most registries maintain a
database of domain names and their associated
contact information. Users can query these
databases through a program called Whois.
-
- WWW
- (World Wide Web) -- Two 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.
- Zone file
- The group of files that reside on
the domain host or name-server. The zone file
designates a domain, its sub-domains and mail
server.
