to be run from Microsoft Explorer browser.


An alternative name for an object, such as a variable, file, or

Anonymous FTP (UNIX only)

Allows for users to access your web site with standard File Transfer
Protocol (FTP) client software in order to upload/download files
without supplying a unique username and password (anonymous). With
the advent of the current HTTP specifications and browsers, however,
this is fairly moot, since the same can be done through your browser.


A high-level program that can be included in an HTML page, most
often an image. The program’s code is then executed by the browser.
Note: Many older browsers cannot interpret Java applets and disregard


Applications software (also called end-user programs) includes database
programs, word processors, and spreadsheets. Figuratively speaking,
applications software sits on top of systems software because it
is unable to run without the operating system and system utilities.


A program that enables you to search for files anywhere on the Internet
by filename.


The precursor to the Internet, ARPANET was a large wide-area network
created in 1969 by the United States Defense Advanced Research Project
Agency (ARPA).


a standard character set.


The process of identifying an individual, usually based on a username
and password.

Backbone (Internet Backbone)

A backbone is a large transmission line that carries data gathered
from smaller lines that interconnect with it. On the Internet or
other wide area network, a backbone is a set of paths that local
or regional networks connect to for long-distance interconnection.

Backup Generator

A alternative source of power, in the event that the standard electrical
services are interupted. Normally, these devices deliver power on
a temporary basis, and run on natural gas or desiel fuel.


The process of copying files so that they are preserved in the case
of equipment failure or catastrophe. If files are damaged on the
server, we resort to the backup copy to restore the files back to
the machine.


The amount of data that can be transmitted in a fixed amount of
time. For digital devices, the bandwidth is usually expressed in
bits per second(bps) or bytes per second. Web hosting accounts usually
offer bandwidth amounts in gigabytes per month.

Thus, the click through rate would be 10% if one in ten people who
viewed the advertisement clicked on it, and landed on the advertisers’

Client/Server Architecture

A network architecture in which each computer or process on the
network is either a client or a server. Servers are powerful computers
dedicated to managing disk drives (file servers), printers (print
servers), or network traffic (network servers). Clients are PCs
or workstations on which users run applications. Clients rely on
servers for resources, such as files, devices, and even processing

Some companies own a server, but want to locate it in the secure
environment of a web hosting provider. That way they can take advantage
of the fastest possible connections to the Internet while handing
over day-to-day management of the site.


A computer buzzword that refers to a program or device’s ability
to link with other programs and devices.


A message given to a web browser by a web server. The browser stores
the message in a text file called cookie.txt. The message is then
sent back to the server each time the browser requests a page from
the server.


Pronounced demon or damon, a process that runs in the background
and performs a specified operation at predefined times or in response
to certain events. The term daemon is a UNIX term, though many other
operating systems provide support for daemons, though they’re sometimes
called other names. Windows, for example, refers to daemons and
system agents and services. Typical daemon processes include print
spoolers, e-mail handlers, and other programs that perform administrative
tasks for the operating system.


A database is a structured set of records, such as a mailing list.
A web browser can access a public database by Perl Scripts. There
are many ways for a user to find information in a database. When
the data is structured as a table in a single file, a user need
only browse the page and use the browser’s “find” feature.
However, to search a relational database spread over many files,
a sophisticated CGI script is required to access the data.

Data Transfer

e-mail. Any HTML, graphic, audio or video file that is accessed
by someone viewing your site is included. High rates of data transfer
indicate a heavily trafficked site.

Dedicated Line

A permanently connected telephone line between two computer systems.
Dedicated lines make up the bulk of the Internet.

Dedicated Server

A dedicated server is a single computer in a network reserved for
serving the needs of the network. For example, some networks require

A major division on a hard drive or server used to divide and organize


A directory is a web site that focuses on listing web sites by individual
topics. A search engine lists pages, where as a directory lists
web sites. On the World Wide Web, a directory is a subject guide,
usually organized by major topics and subtopics. The best-known
directory is Yahoo! Many other sites now use a Yahoo!-like directory
including major portal sites like Excite, Netscape, Lycos, CNET,
MSN, and Niche portals like (for gardeners), (for investors), (for Windows NT administrators),
etc. are also considered directories.

Disk Storage Space

In a shared hosting environment, the amount of server disk storage
allocated to your account. This space can be used to store HTML

Short for Digital Linear Tape, a type of magnetic tape storage device.
DLTs are half an inch wide and the cartridges come in several sizes
ranging from 20 to over 40 GB. DLT drives are faster than most other
types of tape drives, achieving transfer rates of 2.5 MBps.


Short for Domain Name System (or Service), an Internet service that
translates domain names into IP addresses. Because domain names
are alphabetic, they’re easier to remember. The Internet however,
is really based on IP addresses. Every time you use a domain name,
therefore, a DNS service must translate the name into the corresponding
IP address. For example, the domain name might translate

to decrypt it. Unencrypted data is called plain text; encrypted
data is referred to as cipher text. Most e-commerce software applications
utilize encryption technology.


A local-area network (LAN) protocol developed by Xerox Corporation
in cooperation with DEC and Intel in 1976. Ethernet uses a bus or
star topology and supports data transfer rates of 10 Mbps. It is
one of the most widely implemented LAN standards. A newer version

Just like a telephone call, you dial the number of the computer
you are calling and establish a digital connection. It takes only
a few milliseconds and the cost is the same as a normal telephone

ISP (Internet Service Provider)

A company that provides access to the Internet. For a monthly fee,
the service provider gives you a software package, username, password
and access phone number. Equipped with a modem, you can then log
on to the Internet and browse the World Wide Web and USENET, and
send and receive e-mail. In addition to serving individuals, ISPs

maintain log files listing every request made to the server. With
log file analysis tools like WebTrends, it’s possible to get a good
idea of where visitors are coming from, how often they return, and
how they navigate through a site. Using cookies enables Webmasters
to gather even more detailed information about how individual users
are navigating through a site.

search robots to use in adding your pages to their search indexes.
In the absence of any other information, some search engines will
index all words in your document (except for comments), and will
use the first few words (e.g. 250 characters) as a short abstract
to serve back. But meta tags can be used to specify additional keywords
and a short description, which can be used to index the web page
and therefore control the indexing of the web site.

MHz (Megahertz)

A million cycles of electromagnetic currency alternation per second
and is used as a unit of measure for the “clock speed”
of computer microprocessors.

Microsoft FrontPage Extensions

Parked Domains

A parked domain is a reserved domain name that does not load any
web site. It sits in wait on a name server to be used by its owner
at a later date.

Payment Gateway

As it applies to e-commerce, a payment gateway is software that
is hosted on a server that links an online store to a process that
verifies that a customer, who is placing a credit card order, has
the credit available and that the order should be accepted. Later,

Server Side Include (SSI)

A server-side include (SSI) can either be a variable value that
you want to appear on a web page (like the date and time that the
page was loaded on the visitor’s browser – in which case
it must pull this information from the server) or it can be static
information that you want included on several pages.

For instance, you might have 50 pages on
your site and want to use the same navigational bar on each one
of these pages. Without including the same information on all the
pages or using frames, you can make one file that contains the navigation
bar and call to the SSI file on the 50 pages. This way if the navigation
or URLs in the navigation change, then you only have to update the
one file and not the same information on all 50 pages.

Server-Side Scripting and Programming

A variety of scripting and programming languages is available to
you in order to give greater function to your web site. Some of
the primary examples are: Unix, Perl, shell script, Server-Side
Includes (SSI), PHP, Miva (formerly HTMLScript), NT, ColdFusion,
and Active Server Pages (ASP).

Shared Server

Shared web servers are a very popular way of providing low-cost
web hosting services. Instead of requiring a separate computer for
each site, dozens of sites can co-reside on the same computer. In
most cases, performance is not affected and each web site behaves
as if it is being served by a dedicated server.


Software that is distributed at no cost to the user (the author
maintains the copyright).

Shell Access

Access to an interactive user interface where the user can connect
with a Unix operating system. The shell is the layer of programming
that understands and executes the commands a user enters.

Shopping Cart

Shopping cart software acts as an online store’s catalog and ordering
process. Typically, it allows a consumer to browse the web site,
select items for purchase as they browse, review what they have
selected; make necessary modifications or additions, and purchase
the merchandise.


Short for Simple Mail Transfer Protocol, a protocol for sending
e-mail messages between servers. Most e-mail systems that send mail
over the Internet use SMTP to send messages from one server to another;
the messages can then be retrieved with an e-mail client using either


In UNIX and some other operating systems, a software object that
connects an application to a network protocol. In UNIX, for example,
a program can send and receive TCP/IP messages by opening a socket
and reading and writing data to and from the socket. This simplifies
program development because the programmer need only worry about
manipulating the socket and can rely on the operating system to
actually transport messages across the network correctly.

Spider or Robots

It is a program that most of the major search engines on the web
use. Spiders visit web sites and read their pages and other information
in order to create entries for a search engine index. Spiders are
typically programmed to visit sites that have been submitted by
their owners as new or updated. Entire sites or specific pages can
be selectively visited and indexed. Spiders usually visit many sites
in parallel at the same time, their “legs” spanning a
large area of the “web.” Spiders can crawl through a site’s
pages in several ways. One way is to follow all the hypertext links
in each page until all the pages have been read.

SSL Support

Secure Sockets Layer, or SSL, support allows the transfer of data
in a secure environment.
