internetworking products, such as routers, bridges, and switches.
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 or processes 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
power.
Co-located Server
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.
Connectivity
A computer buzzword that refers to a program or device's ability to link with other
programs and devices.
Cookies

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, email handlers, and other programs that perform administrative tasks for the
operating system.
Database
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.

developed by DEC and now marketed by several companies. 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.
DNS
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 www.example.com
might translate to 198.105.232.4.
Document

well as attractive volume discounts.
Encryption
The translation of data into a secret code. Encryption is the most effective way to
achieve data security. To read an encrypted file, you must have access to a secret
key or password that enables you to decrypt it. Unencrypted data is called plain
text; encrypted data is referred to as cipher text.
Ethernet
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 of Ethernet, called 100Base-T (or Fast Ethernet), supports data transfer rates of 100 Mbps. And the newest version, Gigabit Ethernet supports data
rates of 1 gigabit (1,000 megabits) per second.

A packet-switching protocol for connecting devices on a Wide Area Network (WAN).
Frame Relay networks in the U.S. support data transfer rates at T-1 (1.544 Mbps)
and T-3 (45 Mbps) speeds. In fact, you can think of Frame Relay as a way of utilizing
existing T-1 and T-3 lines owned by a service provider. Most telephone companies
now provide Frame Relay service for customers who want connections at 56 Kbps to
T-1 speeds.
Freeware

data.
Anonymous FTP (UNIX only)
Allows for users to access your Web site with standard 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,

features of a packet is that it contains the destination address in addition to the
data. In IP networks, packets are often called datagrams.
Parked Domains
A parked domain points to exactly the same HTML files as the primary domain does
since they share the same IP number. The parked domain cannot point directly to a
subdirectory of the primary domain. It is possible to make users refer to subdirectories and have mail be received at the parked domain, but some of the
``virtualness" is lost and is more technical than can be discussed here.
PERL

send messages from one server to another; the messages can then be retrieved with
an email client using either POP or IMAP.
Sockets
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.
SSL Support
Secure Socket Layer, or SSL, support allows the transfer of data in a secure
environment.

VPN
Short for virtual private network, a network that is constructed by using public wires
to connect nodes. For example, there are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These
systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
VRML
Pronounced ver-mal, and short for Virtual Reality Modeling Language, VRML is a
specification for displaying 3-dimensional objects on the World Wide Web. You can
think of it as the 3-D equivalent of HTML. Files written in VRML have a .wrl extension
(short for world). To view these files, you need a VRML browser or a VRML plug-in to
a Web browser.
W
WAN
A computer network that spans a relatively large geographical area. Typically, a WAN
consists of two or more local-area networks (LANs). Computers connected to a wide-area network are often connected through public networks, such as the

and updating Web pages, Replying to user feedback, Creating CGI scripts, Monitoring
traffic through the site.
Web Server
A computer that delivers (serves up) Web pages. Every Web server has an IP
address and possibly a domain name. For example, if you enter the URL http://webhosting.vds.com/index.html in your browser, this sends a request to
the server whose domain name is vdswebhosting.com. The server then fetches the page named index.html and sends it to your browser.
Whois
