The web doesn't have to be
confusing. Here are a few terms to help you understand the basics
of what you need to know for dealing with the internet.
- Bit
- Binary Digit—a single digit number in base-2,
i.e. either a 1 or a zero. The smallest unit of computerized Bandwidth
is usually measured in bits-per-second.
- Bps
- Bits-Per-Second— measurement of how fast data is
moved from one place to another. A 28.8 modem can move 28,800
bits per second.
- Browser
- Software that is used to look at various kinds of
Internet resources. The most common are Microsoft's Internet
Explorer and Netscape's Navigator. It’s what is surrounding the
web page you are now viewing.
- Byte
- Think of this as the smallest unit of measurement
for electronic data. Technically, it is 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.
- 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
- cgi-bin
- The most common name of a directory on a web server
in which CGI programs are stored.
- Client
- A software program that is used to contact and
obtain data from a server software program on another computer.
- Cookie
- Information sent by a site you visit that is stored
on your computer which sends information back to the site the next
time you visit it. This is how some sites keep track of your
preferences. In some cases, you may not like cookies. In some cases,
a site will not function properly unless cookies are enabled on your
computer.
- Cyberspace
- This refers to the universe of electronic
connections.
- Design
- Web design. This refers to the theme: the overall
look of the website. A web design should be consistent so that
visitors know that they are on the same site. It should also be
interesting without having too many fancy, moving effects which
become boring quickly. A good web design makes the information
easily obtained and doesn’t focus too much on the effects.
- DNS
- Domain Naming System—Links domain names to an IP
number.
- Domain Name
- The names you use to find a site:
auroraartisans.com: 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 short while ago, the names were primarily
.com, .net, .org., .gov, and .edu. The .edu extensions are reserved
for educational institutions, .gov for government sites, .com
originally was for commerce sites, .net for either business or other
internet sites, and .org for organizations, often charitable ones.
Now, however, .com is by far the most popular for any internet site,
mostly because users often forget to put on the ending extension and
have an easier time finding .com sites.
- E-Commerce
- Electronic Commerce—buying and selling by way of
the Internet.
- E-mail
- Electronic Mail—mail sent over the internet
electronically.
- Ethernet
- A common method of networking computers in a LAN.
- FAQ
- Frequently Asked Questions—usually a good place
to find answers you have about a site.
- Fire Wall
- A protection against computer invasion through a
combination of hardware and software.
- Flash
- Software developed by Macromedia which makes a kind
of movie on the site. This can make the site look very high
tech. The problem is that although site owners love the
effects, most visitors hate them, and most Flash is done so poorly,
that it looks as though it were developed by a third grader.
Done well, flash adds to the site, but also adds complication and
expense.
- Frames Page
- Frames pages make a neat design. If this were
a frames page, the text would appear to slide under the border on
top. The trouble with frames is that (1) not all browsers can
display them, so some visitors can't see them, and (2) search
engines [with the possible exception of one] don't index them.
This means that unless you have an established clientele and don't
want additional internet traffic, a frames page set up will not work
for you.
- Gigabyte
- 1024 Megabytes
- hit
- A single request from a web browser for a
single item from a web server. In order for a web browser to
display a page that contains 4 graphics, 5 'hits' would occur at the
server: 1 for the HTML page, and one for each of the 4
graphics.

- Usually this refers to the index page, the first,
or main page of a website. It also refers to the page to which one’s
computer opens the browser upon starting.
- Host
- Any computer on a network that is a
repository for services available to other computers on the network.
- Hosting
- Typically this refers to a service provided by a
company that uses servers to store and make websites available.
Usually there is a regular fee for this.

- .jpg or .jpeg file
- These are picture, or image, files. Picture files
can be stored in various files such as .tif, .gif, .mic, .bmp, and
so on. Most picture files for the internet or for e-mail should be .jpg
files since these files are compressed enough in terms of the
kilobyte size that they can be sent. .gif files are also useful for
the internet and are used for pictures with motion or in which one
doesn’t want the background to show.
- Kilobyte
- A thousand bytes [More specifically, 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.

- Login
- The account name used to gain access to a computer
system or the act of entering such a system.
- Maillist
- or Mailing List

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. This allows many people to participate in discussions.- Megabyte
- A million bytes. A thousand kilobytes.
- 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.

can both send and receive files using the MIME standard.
- Mirror
- An exact copy—typically refers to sites that have
two names, but identical material.

- Name Servers
- A computer that performs the mapping of easily
remembered domain names to IP addresses. Sometimes referred to as a
host server.
- Network
- Any time two or more computers are connected so
that they can share resources, it is a computer network. Two or more

by client and server software to carry USENET
postings back and forth over a TCP/IP network
- Parking
(Domain Name)
- A domain name which has been registered, but is not
being used for a website is referred to as "parked." Some
companies put up pages for such parked names that say "for
sale," or "under construction." Without that, a name
that is registered but not being used will result in a "page
cannot be displayed" page.
- 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 clue7. A good password would be:
sTrong-9
- Plug-in
- A piece of software that adds features to a larger
piece of software.
- 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
- First and generally, a place where information goes
into and/or out of a computer, e.g. a serial port or usb port on a
personal computer.
- 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.
- 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
- As a noun—single message entered into a network
communications system such as a message posted to a message board.
- As a verb—putting a message on the web.
- 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 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
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.
- Register
(Domain Name)
- This is the process of buying a domain name that
reserves the name for that individual or organization for a
specified length of time. Once a name is registered, it can’t be
used by anyone else.
- Registrant
(Domain Name)
- The person or organization who has register the
name.

- Most domain names need to be renewed at some
scheduled yearly interval. Names that expire, are not renewed,
become available to someone else.
- Resolution
(domain Name)
- The conversion of an internet address or domain
name into the corresponding physical location.
- Router
- A special-purpose computer (or software package)
that handles the connection between two or more networks.
- Search Engine
- Companies that list websites by keywords or search
words so that people looking for information can find the sites with
that information. With many millions of sites to list, it is
difficult getting listed by search engines. The most popular ones,
such as Yahoo and Google, have a reputation for being the most
comprehensive for listing sites and for yielding the best results.
- 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.
- Server
- A computer, or a software package, that provides a
specific kind of service to client software running on other
computers. Typically, this refers to large computers that host
numerous websites.
- 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.
- 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 e-mail 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.
- Spam (or Spamming)
- Repeated posting of a message. This is considered
inappropriate use of the internet and is grounds for host companies
to take away someone’s website without reimbursement of fees. A
site that tries to get listed by a search engine by submitting
numerous times is considered to be spamming, and will not be listed
at all. Sending out messages to lists of e-mail addresses of people
who don’t wish to receive the message and have not contacted the
sender is considered spamming, and is grounds for losing one’s
e-mail.
- SQL
- Structured Query Language—A specialized
programming language for sending queries to databases.
- 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.
- 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.
- 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.
- Template
- A set design into which your site information is
plugged. This allows only minor variation and makes your site
look amateurish.
- 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.
- 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.
- Top Level Domain: (TLD)
- The Top Level Domain refers to the extension such
as .com, .net, .org, .gov, .edu, and so on. The second level is the
unique name before the .com.
- Trademark
- If a domain name which is a trademarked name, it is
possible that the name can be taken away. Therefore, it’s a good
idea to check before registering a name to be sure that it is not
someone’s trademark. The process for getting a name back is
expensive, and trademark law differs from country to country.
- 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), such as http://www.yahoo.com.
- 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
- WAN
- Wide Area Network—Any internet or network
that covers an area larger than a single building or campus.
- Web
- WWW or World Wide Web
- 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)— 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.
