- 10BaseT
- 10 Megabit per second baseband Ethernet
specification using two paris 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 Mebabit per second baseband Fast
Ehternet 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 benefitial 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 substring 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.

- ATM
- ATM -- Asynchronous Transfer Mode.
International sandard 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 transmited 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
MyWebSiteTool.Net offer the ability for customers to place their
webservers and other network equipment in thier 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 nameservers to map easily remembered domain names to
an IP number.
- Dedicated
Server
- For those customers that want the
advantages of colocation without the hassles of purchasing their
own server. See colocation.
- 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:
mywebsitetool.com, ftp.mywebsitetool.com,
whatever.mywebsitetool.com 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 shorthands 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 nameservers
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 (webhosting, 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 nameservers
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
organziations. 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 nameservers 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,
mywebsitetool.com is our domain name. The "com" is
considered the TLD and the "mywebsitetool.com" 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://www.mywebsitetool.com/cheapwebhosting/ 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 Souce: 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 nameserver. The zone file designates a domain,
its subdomains and mail server.
